2026 US Mechanical Engineer Survey Results

550 Upvotes

I would like to thank you everyone for participating in the annual 2026 ME Salary survey. Total respondents was a little over 600, so less than last year, but about 589 US responses.

Past Results Link

Background:

Here are the main results. It took about 2 hours to "clean" the data manually. Afterwards, I basically used Gemini to create the graphs + tables, since last time it literally took me about 7 hours to do everything manually on Excel last time and there were still questions. The key points and takeaways from the data is a combination of AI and editing the information to be more readable (still took 4 hours). In addition, I wouldn't worry about math too much, since Gemini basically just used python code to decipher the edited CSV file.

Industry:

Industry Number of Respondents
Manufacturing 175 (29.7%)
Aerospace/Defense 173 (29.4%)
Technology (FANG, AI, Robotics, etc.) 54 (9.2%)
MEP (HVAC, Construction, etc.) 38 (6.5%)
Utilities (Power, Renewables, etc.) 35 (5.9%)
Pharmaceutical & Medical Devices 31 (5.3%)
Oil and Gas 28 (4.8%)
Consumer Goods 15 (2.5%)
Government 11 (1.9%)
  • There were some other industries like nuclear, logistics, and etc. but the few data points aren't included in the table for brevity. The data was included in the total set though
  • A majority of the mechanical engineers trends will use the Aerospace/Defense and Manufacturing data since there is the most data that is available

Salary and Year of Experience:

*Note: Total Compensation/Salary = Base Salary + Bonus + RSU + Base Salary * 401k Match

If you want to look at one graph and table to explain the progression track here it is:

YOE Range Median Base (Unadj) Median Total (Unadj) Median Base (COL Adj) Median Total (COL Adj) Count
0-1 Year $87,000 $96,036 $81,699 $87,368 43
2 Years $84,000 $91,046 $84,615 $90,909 71
3 Years $94,550 $105,965 $94,082 $102,289 62
4-5 Years $104,000 $119,770 $94,881 $107,762 116
6-8 Years $120,000 $136,800 $112,500 $127,911 119
9-12 Years $125,500 $146,985 $123,444 $142,555 96
13-20 Years $157,290 $181,840 $144,254 $171,731 64
20+ Years $196,500 $211,426 $163,399 $191,042 15

Key Takeaways:

  • The "Benefit Gap": The space between the solid lines (Total Compensation) and the dashed lines (Base Salary) represents the added value from annual bonuses and employer 401k matching. For a mid-career engineer (6-8 years), this extra value is roughly $16,800 on average.
  • Late Career Leverage: As engineers gain seniority (13+ years), the gap between base salary and total compensation grows significantly, suggesting that bonuses and incentive programs make up a larger portion of the package for senior-level and leadership roles.
  • Purchasing Power: The COL Adjusted lines (Orange) consistently track below the un-adjusted lines (Blue), highlighting that high-paying mechanical engineering roles are frequently located in markets where the dollar doesn't stretch as far as the national average.

Education:

  • Majority of the respondents are at max a bachelor degree holder. However, there is still a significant number of master's students

Now about the age old question: does having a Master's degree lead to higher future salary?

Short Answer: In general, the answer is yes if there is a chance to specialize. It is explained in the table below:

Industry Career Stage Education Median Total (Unadj) Median Total (COL Adj) Count
Aerospace & Defense 0-3 Years Bachelors $96,664 $95,201 44
Masters $116,600 $108,316 15
4-7 Years Bachelors $125,410 $110,659 39
Masters $173,000 $148,432 9
8-15 Years Bachelors $161,750 $140,202 33
Masters $154,905 $149,658 16
15+ Years Bachelors $207,080 $187,505 7
Masters $211,426 $207,872 5
Manufacturing 0-3 Years Bachelors $88,220 $93,452 52
Masters $93,740 $91,850 6
4-7 Years Bachelors $108,992 $106,701 45
Masters $129,800 $128,407 12
8-15 Years Bachelors $135,425 $142,440 44
Masters $136,298 $129,984 8
15+ Years Bachelors $182,650 $187,127 5
  • Now you can see that for manufacturing, the benefits is not as prominent, while it is evident in aerospace. This makes sense, since Aerospace have very high specialization salary, for instance: hypersonic or eVtol which pays a ton for total compensation based on years of experience.
    • Answer: if your company pays for your masters, do it, but it doesn't seem that beneficial near the end of your career.

Internships & Coops:

Key Insights:

  • The "Experienced" Majority: A combined 85% of respondents completed at least one internship or co-op. This underscores how critical early-career work experience has become for landing a full-time role in mechanical engineering.
  • Co-op Advantage: The 20% of respondents with "3+ Internships" often represent those in formal co-op programs (where students rotate between school and work over several years). These candidates typically command higher starting salaries shown in the table below:
Industry 0-1 Internship 2+ Internships New Grad Premium
Aerospace & Defense $82,000 $91,500 +$9,500
Manufacturing $74,000 $82,000 +$8,000
MedTech $80,500 $89,000 +$8,500

Certifications:

Here is the graph of a major certifications from the survey:

We always see a question on whether certifications are worth it:

Aerospace & Defense: Certification vs. Total Compensation

Experience Education Has Cert? Median Unadj. Total Median Adj. Total Count
0-3 Years Bachelors No $97,900 $95,426 41
Yes $95,040 $64,653 3
4-7 Years Bachelors No $125,315 $106,672 36
Yes $128,580 $138,258 3
8-15 Years Bachelors No $159,660 $139,839 31
Yes $280,425 $177,895 2
Masters No $151,410 $142,043 13
Yes $209,658 $216,142 3

Manufacturing: Certification vs. Total Compensation

Experience Education Has Cert? Median Unadj. Total Median Adj. Total Count
0-3 Years Bachelors No $88,020 $91,944 43
Yes $90,450 $99,746 9
4-7 Years Bachelors No $108,805 $106,615 36
Yes $108,992 $106,701 9
8-15 Years Bachelors No $135,000 $136,541 31
Yes $136,000 $151,111 13
Masters No $152,212 $122,728 6
Yes $134,815 $141,636 2

Key Findings:

  1. High-Experience Premium in Aerospace: The most dramatic impact of certification appears in the mid-to-late career in Aerospace & Defense (8–15 years). Engineers with a Bachelors and a certification earn a median total compensation significantly higher than those without. Even among Masters holders in this range, certified engineers have a median total comp of $209k vs $151k for non-certified.
  2. Manufacturing Stability: In the Manufacturing industry, certifications (often Six Sigma or FE/PE) lead to a very modest increase in un-adjusted base pay, but a more noticeable improvement in COL-adjusted pay. This suggests that certified engineers in Manufacturing may have more flexibility to find high-paying roles in lower-cost-of-living areas.
  3. The "Entry-Level Paradox": For junior engineers (0–3 years), having a certification (likely the FE) does not immediately result in a salary premium. In fact, in Aerospace, the un-adjusted median for those with certifications was slightly lower, possibly because those engineers are still in entry-level rotation programs where pay is standardized regardless of credentials.
  4. Masters + Certification: For those who already have a Masters, adding a certification provides a significant late-career boost (as seen in the 8–15 year group in Aerospace).

Answer: Certification can be worth it for select industries. PE is known for civil to open doors and increase pay.

Job Titles:

Job Role Category Number of Respondents Percentage
Mechanical Engineer (General) 229 38.9%
Design Engineer 97 16.5%
Project & Systems Engineer 59 10.0%
Management & Leadership 55 9.3%
Manufacturing & Process Engineer 54 9.2%
Specialized (Thermal, Stress, R&D) 34 5.8%
Other / Misc 61 10.4%

Key Insights:

  • General vs. Specialized: Nearly 40% of respondents identify with the broad title of "Mechanical Engineer," which often includes generalists or those in mid-level positions.
  • The Design Dominance: Design Engineering is the second largest single group, reflecting the high demand for CAD-based design and product development across aerospace, tech, and manufacturing industries.
  • Transition to Leadership: About 9% of respondents hold titles in Management & Leadership (Manager, Director, VP), which led to a higher salary
  • Project and Systems focus: 1 in 10 engineers focuses on Project or Systems Engineering, highlighting the importance of multidisciplinary coordination and technical management in modern engineering projects.
  • The Specialty Niche: The "Specialized" category includes highly technical roles like Thermal Analysis, FEA, Simulation, and Research & Development, which often require higher educational levels or deep domain expertise.

Salary Grade vs. Salary:

Grade Level Industry Median Annual Salary Typical Experience (YOE) Sample Count
Level 1 (Entry) Aerospace & Defense $88,400 1.0 year 39
Manufacturing $80,250 2.0 years 39
Level 2 (Mid) Aerospace & Defense $102,273 3.8 years 48
Manufacturing $95,000 5.0 years 71
Level 3 (Senior) Aerospace & Defense $130,000 8.0 years 57
Manufacturing $119,600 9.0 years 50
Level 4 (Lead/Manager) Aerospace & Defense $170,500 11.0 years 22
Manufacturing $136,000 11.0 years 11
Level 5+ (Principal/Director) Aerospace & Defense $206,000 20.0 years 9
Manufacturing $136,500 14.0 years 4
  • Efficiency of Experience: In Aerospace, engineers tend to reach Level 2 and Level 3 roughly 1–1.2 years faster than those in Manufacturing, while also earning more.
  • The Level 4 Ceiling: In Manufacturing, the salary jump from Grade 3 to Grade 4 is roughly $16k, whereas in Aerospace, that same promotion yields a massive $40k jump in median base salary.

Which Industry Pays the Most?

Major Caveat: at 16+ YOE, the data points are only a couple, which skews the data upward.

Based on the comprehensive US survey data, the Technology (FANG, Robotics, AI, Consumer Electronics) industry emerges as the highest-paying sector for mechanical engineers when considering total compensation (Base Salary + Annual Bonus + 401k Match).

Tech Compensation Package:

Years of Experience Avg. Total Comp (Unadjusted) Avg. Total Comp (Adjusted for COL) Number of Respondents
0-2 YOE (Entry) $117,316 $100,292 7
3-5 YOE (Junior) $180,854 $138,040 17
6-10 YOE (Mid-Level) $182,773 $134,543 14
11-15 YOE (Senior) $259,993 $220,256 11
16+ YOE (Principal) $244,775 $177,043 5

The Oil and Gas industry stands out as the second most lucrative sectors for mechanical engineers, particularly as they reach senior and principal levels. While Tech offers the highest overall unadjusted compensation, Oil and Gas actually offers the highest Cost of Living (COL) Adjusted compensation, meaning your real purchasing power in this industry is the highest among all major sectors.

Years of Experience Avg. Total Comp (Unadjusted) Avg. Total Comp (COL Adjusted) Number of Respondents
0-2 YOE $95,864 $83,178 5
3-5 YOE $117,289 $111,155 7
6-10 YOE $138,959 $139,773 7
11-15 YOE $204,097 $219,757 6
16+ YOE $408,040 $399,276 3

Overtime Pay:

Industry Trends: Overtime pay is slightly more common in Manufacturing (where production deadlines are rigid) and Consulting/EPC (where hours are billable to clients) compared to R&D or Aerospace.

Work Hours:

Work Hours Category Number of Respondents Percentage
Exactly 40 Hours 337 57.2%
41-45 Hours 146 24.8%
46-50 Hours 49 8.3%
<40 Hours 50 8.5%
>50 Hours 7 1.2%

Key Observations:

  • The "40-Hour" Standard: Over half of the engineers surveyed manage to stick to a strict 40-hour week, which is a positive sign for work-life balance in the profession.
  • Moderate Overtime: Roughly a quarter of engineers work an extra 1 to 5 hours a week (41-45 hours total), often representing "straight time" or expected professional dedication without formal overtime pay.
  • The High-Hours Exception: Only a small fraction (under 10%) report working more than 45 hours consistently. This is significantly lower than in fields like investment banking or high-tier management consulting, suggesting a relatively stable lifestyle for most US mechanical engineers.
  • Flexibility: About 8.5% of respondents work fewer than 40 hours, which often aligns with part-time roles, senior consultants, or companies with flexible "9/80" schedules where some weeks are shorter.

401k Summary:

Match Rate Range Count of Responses Percentage
4% - 5% 211 35.8%
1% - 3% 125 21.2%
6% - 7% 120 20.4%
8% - 10% 65 11.0%
No Match (0%) 56 9.5%
> 10% / Other 12 2.0%

Key Takeaways:

  • The Industry Standard: A 4–5% match is clearly the most common benefit, covering over a third of the surveyed population.
  • High-Tier Benefits: Roughly 13% of engineers receive a match of 8% or higher, which often indicates highly competitive benefit packages in specialized industries.
  • Retirement Security: The low percentage of "No Match" responses (under 10%) highlights that retirement contributions are a standard and expected part of total compensation in the US mechanical engineering market.

Remote Work Distribution:

Remote Category Number of Respondents Percentage
Fully In-Person (0%) 248 42.1%
Mostly In-Person (1-39%) 163 27.7%
Hybrid (40-60%) 118 20.0%
Fully Remote (100%) 38 6.5%
Mostly Remote (61-99%) 22 3.7%

Key Insights:

  • The "Hands-On" Requirement: Over 40% of mechanical engineers are required to be in the office or on-site 100% of the time. This is significantly higher than other engineering fields like Software or Data Science.
  • The Hybrid Standard: Roughly 48% of the workforce has some form of hybrid flexibility (ranging from 1% to 60% remote). Many companies now allow 1–2 days of remote work for documentation, CAD modeling, or administrative tasks.
  • Fully Remote is Rare: Only 6.5% of mechanical engineers work fully remotely. These roles are typically in specialized areas like pure Simulation/FEA, Project Management, or Sales Engineering where physical hardware access is not required daily.
  • The Hybrid Middle Ground: The 40–60% range (often 2–3 days per week) is a common "sweet spot" for engineering firms trying to balance teamwork/lab time with employee flexibility.

Paid Time Off (Days):

*Note: one issue is many jobs had unlimited sick time, which I just added 10 days. Next time I will edit the form to separate the sick days so it makes more sense.

PTO Category (Includes Sick Days) Number of Respondents Percentage
0–10 days 30 5.2%
11–15 days 112 19.5%
16–20 days 160 27.9%
21–25 days 100 17.4%
26–30 days 61 10.6%
31+ days 32 5.6%
Unlimited 78 13.6%

Key Insights:

  • The " 3 - 5 Week" Benchmark: The majority of mechanical engineers (over 45%) receive between 16 and 25 days of PTO.
  • The Rise of Unlimited PTO: About 13.6% of respondents now have "Unlimited" PTO.
  • Generous Packages: Roughly 16% of engineers receive more than 30 days of PTO, which is often a hallmark of high-seniority roles, government/defense positions, or companies that reward long tenure.
  • The Lean End: Only about 5% of respondents are on the low end with 10 days or fewer, suggesting that a minimum of two weeks of PTO is a standard baseline for the industry.

Now some of you might have questions regarding years of experience and PTO:

Average PTO by Experience (Fixed PTO)

Experience Level Average PTO Days (per year) Typical Range (25th-75th Percentile)
0–2 Years 16.9 10–15 days
3–5 Years 19.6 15–20 days
6–10 Years 21.1 20 days
11–15 Years 24.5 20–25 days
16+ Years 26.5 25–30+ days

Analysis of the Trend:

  • The "Standard Jump": Many engineers start with 15 days (3 weeks) and see their first significant "tenure bump" to 20 days (4 weeks) after reaching the 5-year mark.
  • Senior Perks: By the time an engineer hits 15+ years of experience, a 5-week (25-day) or 6-week (30-day) PTO package becomes the new baseline.
  • Job Hopping Factor: The data suggests that while tenure within a single company increases PTO, "job hopping" every 3–5 years also allows engineers to negotiate higher starting PTO tiers at their new employers, effectively "skipping" the long wait for tenure-based increases.

Health Insurance:

Satisfaction Level Number of Respondents Percentage
Free / Excellent 38 6.5%
Good (Low Premium/High Coverage) 211 36.3%
Average 288 49.5%
Poor (High Premium/Low Coverage) 41 7.0%
Other / Misc 4 0.7%

Key Insights:

  • The "Standard" Plan: Almost 50% of engineers describe their insurance as "Average," highlighting that standard employer-sponsored health insurance is common but not particularly outstanding in terms of premiums or coverage levels.
  • Competitive Benefits: Over 42% of respondents fall into the "Good" or "Free" categories. The 6.5% who receive "Free/Excellent" coverage likely work for highly competitive tech firms, established defense contractors, or companies that use premium benefits as a retention tool.
  • Under-Served Minority: Roughly 7% of the engineering workforce feels their health insurance is "Poor," usually characterized by high out-of-pocket costs and high monthly premiums.

Biggest Cons for Mechanical Engineering:

Category Typical Concerns Mentioned
Workload & Hours (112 mentions) High pressure, tight deadlines, long hours, and poor work-life balance. Many mentioned "start-up energy" even in established firms.
Salary & Compensation (73 mentions) Low raises (2–3%), "salary plateauing" early in the career, and the absence of stock options or significant bonuses compared to tech.
Remote Work Limits (47 mentions) Frequent requirements to be in the office or on the manufacturing floor with "no remote option" or "No WFH" (Work From Home) policies.
Career Growth (35 mentions) Concerns about "pigeon-holing," slow internal promotion tracks, and becoming "stagnant" in one technical area.
Red Tape & Bureaucracy (26 mentions) Excessive paperwork, slow corporate processes, "red tape," and inefficient management systems.

Biggest Pros for Mechanical Engineering:

Category Typical Benefits Mentioned
Salary & Comp (86 mentions) Competitive base pay, annual bonuses, and strong 401k matching programs.
Work-Life Balance (75 mentions) Flexible schedules, reasonable working hours (standard 40h), and generous PTO.
Culture & People (70 mentions) Great teammates, supportive management, and a collaborative "team-first" environment.
Interesting Work (65 mentions) Designing "cool" products, working on challenging technical problems, and having a clear mission.
Job Stability (28 mentions) Long-term security, consistent demand for the role, and the stability of established firms.
Remote/Hybrid (27 mentions) The ability to work from home part-time or have flexible geographic location.

Direct Insights from Engineers:

  • On Work Quality: "The actual work we do is really interesting, fun, and rewarding. Getting to see a design go from CAD to a physical product is the best part."
  • On Culture: "Great coworkers and a team environment where people actually mentor you instead of just giving you tasks."
  • On Flexibility: "Remote flexibility and a management team that trusts you to get your work done without micromanaging your hours."
  • On Compensation: "The total compensation package—including the 401k match and the annual bonus—makes the technical pressure worth it."

Now for Improvements on Suggestions on the Survey:

  1. Regarding the COL instructions: totally my fault, sorry for not catching it. All of you were able to figure it out, but changed instructions from 0 - 2, so it makes a lot more sense now.
  2. Adding a column for manager and IC: totally good suggestion, already added to new survey for 2027
  3. Regarding adding gender or age: I will not add this into the survey just to make it more anonymous. I really do not see the value in this data, and I recommend just using government data to find the data.
  4. Regarding the health insurance question: I have implemented the change on making it have three questions: annual premium, annual deductible, person coverage. I really did not want to make this part too complicated with max out of pocket and copay and etc. I think the premium, coverage and deductible is acceptable amount.
  5. Edited the salary section to organize the % 401k match, salary, bonus, RSU to be in the same section making it easier, but separated the questions.

Comparison from the 2024, 2025 and 2026 Reddit Survey Results will be in another post, since this post is getting insanely long. Again, any other improvements or suggestions, please just comment below.

Post Grad - Rural Life

44 Upvotes

Hi everyone!

Recently graduated in May of 2026 with a Bachelor in Mechanical Engineering. Finally landed my first offer for a very great position around 100k that includes sign-on and relocation assistance. As for the location, it is in a rural area about 1hr 20min from deep in Chicago, around 45 miles west of Joliet. I’ve always wanted to live on the west coast but that is likely not the case. Any new grad engineers or people that have been out in the field for a while enjoy working far away from the big city? I just wish to be surrounded by youth and activities to do when i’m not so bored outside of work. I get Chicago is about an hour drive so very close, but I still want to hear your opinions.

Edit:

Also working at a Nuclear Power Plant and my title is "Mechanical Engineer", maybe if the plant is down, could be 12 hour shifts, but benefits are competitive.

How important is gpa really?

8 Upvotes

I’m a junior in mechanical engineering. I’ve had two internships so far in construction and I’m looking for a third. I’ve taken a lot of credit hours this semester and I have admittedly fallen behind on my classes and I think my overall gpa after this semester will be just above a 2.5. Are my career prospects in things outside of construction shot? Like realistically how hard is life going to be post grad.

are techs not humans?

166 Upvotes

this is a RANT, please read only if you are interested. i have a bachelors in MechE and a recent grad. I am genuinely disturbed/maybe even disgusted? about how some engineers treat techs.

Did a technician role at a manufacturing place and full time tech at an industrial automation place currently. Both places same situation, any process improvement suggestions or DFM feedback instantly gets put down and ignored. I have witnessed this and also have personally experienced these situations multiple times. To me most of these suggestions were more than valid and would not come at any additional effort/expense while yielding much better outcomes.

Above all else, it’s just the whole demeanor most engineers have towards techs is what i dislike. In this short time in experience I have already seen so much oversight from these experienced engineers on design choices, poor planning and execution.

Constantly up-revving to make their designs work and impress others. While the first ones to blame always comes down to production where the techs have to suffer even though 90% of the time the causes are design flaws.

unfortunately this is a bit steep but I don’t like engineers anymore, most of them that I have encountered are way too full of themselves.

Good technicians are the backbone of the entire manufacturing operation and more companies should realize that if not already.

I personally am doing tech roles because i like hands on work and being on the shop floor. Also as a new grad with no internships I can’t get no engineer roles which I will absolutely admit. But gaining exposure in technician roles has made me a lot more aware of what to do and not to do when on the other side.

Feel free to downvote and if you read till the end, thank you for reading this blabber post

Any recommendations for CAD courses about parts design, mechanical drawings and 3D modelling (automotive field if possible)? (Like youtube channels or Udemy/Coursera courses)

2 Upvotes

Hey guys, I already have a few years of experience with 2D CAD and 3D modeling in Autocad and Solidworks.

But for the past 5 years I've been out of the technical field and I want to get back into it, and transition into the automotive field as my previous experience was with mining.

I'm looking for stuff that goes more into advanced parts design/modeling and drawings, "industry level" stuff, if that makes sense.

Most of what I'm finding goes more into the software tools itself (where commands and tools are and what they do), and it doesn't seem to have more complex parts design/assemblies and industry level parts design and production.

Even though my reading comprehension of 2D mechanical drawings and ability of making 3D models after them is still ok, but my ability of designing something and then making it 2D for example for actual production level, making detailed specifications etc., is what have gotten quite poor.

So I'm looking for more professional parts design 2D and 3D also for production, especially on the automotive engineering industry.

Thanks guys!

I developed an open-source 3D preliminary design and CAD tool for Kaplan and Deriaz hydraulic turbines (Python/MATLAB) [OC]

Thumbnail

15 Upvotes

Hi everyone! As part of my Master's thesis in Industrial Engineering, I noticed a major gap in the engineering software landscape: while there are great open-source tools for wind turbines (like QBlade) and propellers, finding free, open-source software for preliminary design in hydraulic turbomachinery (especially for reversible pump-turbines like the Deriaz turbine) is surprisingly difficult.

To solve this, I built KaplanDeriaz3D, a fully open-source Python and MATLAB application designed to parameterize, compute, and model the 3D geometry of Kaplan and Deriaz turbine blades from fundamental fluid mechanics and Euler’s turbine equation.

Key features:

Hydrofoil Generation: Custom options including standard NACA profiles, anti-cavitating profiles, and reversible hydrofoils for pump-turbine operation.

3D Parametric Export: You can adjust rotational speed, net head, volumetric flow, and mesh resolution, then instantly export the full solid runner geometry as an STL file. (Fun fact: I 3D printed a working physical scale model of the Deriaz runner with rolling bearings, it acts almost like a functional fidget spinner!)

Fully Documented: Includes my complete 100-page master's thesis explaining all mathematical models and equations.

If you are into fluid dynamics, clean energy systems, or want to check out the source code, everything is available on GitHub. I also recorded a full video walkthrough explaining the theory, the UI, and how to export STLs for prototyping:

🔗 Video Walkthrough: https://youtu.be/9rINCHj3ucU

Bachelor's in Bioengineering to Master's in Mechanical Engineering?

• Upvotes

I graduated with a bachelor's degree in bioengineering 3 years ago and have been working as a field engineer for an OEM doing install, maintenance, and qualification/validation for the pharma industry.

As a lot of people who get BioE degrees I thought it would be more... mechanical. Right now I am considering going back to get my MS in mechanical engineering to get a mechanical design role at an OEM of scientific instrumentation and pharma equipment.

What are my chances of getting into MS programs? Would mechanical design roles take my degree combo?

What can I expect my field engineering experience to count for if anything?

I am not rolling in it but I make decent money plus a bit of overtime and sales lead incentives. I would be fine with a lateral move in compensation and an entry level job title but it if its too far of a setback I'll probably consider other options.

Any input is really appreciated.

Starting school soon, what do I focus on to be able to work for some of the top golf companies?

My dream would be to work for titleist callaway taylormade or any of the other golf brands designing and testing clubs. How should I focus my school? I already have a bachelors in chemistry with 10 years manufacturing/analytical/process improvement experience so I hope those help my case.

Measure Small Parts with Phone Camera (Metrology)

Post image
0 Upvotes

I thought it might help you in projects. I have created a free web tool to measure small parts with just a phone camera.

  1. Place the part beside a reference ( for example: a scale ruler). Click a photo.
  2. Select 2 points to specify a reference line. Input the length of the reference line into the "Reference Length Line".
  3. Zoom in/out for accuracy. Move around. Select points on the part to measure Length, Radius or Angles.

It works on desktop and phone. Please let me know your user experience, I will improve it. Or you can improve it yourself on Github.

Cal Poly SLO MechE or Civil?

2 Upvotes

In my heart, I think MechE is the better fit. But I know how hard it can be to get into mechanical. I initially went down the civil path since my college doesn’t offer some of the major required courses for MechE, but the new Fall 2027 required courses align better with me.

I still need to take the applied programming (required course), which would be completed spring 2027. I could also bang out a couple of the desired courses for MechE. But would that be too risky or decrease my chances since I’m taking the classes after I submit my application?

Would it be safer for me to apply as civil engineering? I am applying as mechanical engineering for every other college I’m applying to.

what do you think are genuine signs that someone isn’t cut out for engineering, versus simply being in the wrong environment or struggling with burnout?

Did you also ever reach a point in your career where you almost gave up on engineering? If so what happened? Where are you today?

ASME B31.3 pressure design: How do you handle corrosion allowance & mill tolerance in your quick check routines?

2 Upvotes

Hey everyone,

Quick design question for the piping / pressure vessel engineers here working with ASME B31.3.

When doing quick sanity checks on required pipe wall thickness (t_{req}) for high-pressure lines, I’ve noticed a lot of variation in how different engineering teams handle c (corrosion/erosion allowance) and T_{mill} (mill tolerance, usually 12.5%) during early design stages.

Specifically:

  1. Do you usually factor in the 12.5% mill undertolerance directly into the nominal thickness selection right away, or do you run the exact calculated t_m value through a standardized lookup routine first?
  2. For temperature-dependent S (allowable stress) values, how often do you rely on quick digital lookup sheets vs manually cross-referencing Table A-1 in the code book when double-checking vendor design packages?

I've been scripting a lightweight internal lookup utility to automate these repetitive B31.3 / B16.5 checks for field/site reviews, but I want to make sure the calculation flow and output breakdown reflect standard industry practices.

Curious to hear how your teams streamline these code verification routines or if there are specific edge cases that usually cause headache in field checks.

(Happy to share the test script/tool privately via DM if anyone wants to look at the math logic, but mainly looking for design workflow thoughts here.)

Thanks!

Personal project documentation

1 Upvotes

I'm an incoming Mechanical Engineering student working on a rocket flight simulation and telemetry system. The software side uses MATLAB to simulate rocket flight, and I'm planning to build the hardware side using an Arduino, sensors and an SD card for data logging.

I eventually want to showcase the project on GitHub and in my engineering portfolio for internship applications.

What's the usual process after completing a project? What should I upload to GitHub, document in a test report, and include as screenshots, graphs and hardware photos? How do I make the whole thing portfolio-ready?

Would appreciate advice from anyone who's done this before!

How many prototypes is too many? I hit 41 on a small mechanism

I'm a mechanical engineer and recently went through 41 iterations on a small print-in-place mechanism: a free-spinning drum with a button brake. Part of it was learning print tolerances, but I also spent weeks on a feature (printed bearings) that I ended up cutting.

For those of you in product development, how do you decide when to stop iterating on a feature versus cutting it?

Is delaying graduation for an aerospace internship worth it?

15 Upvotes

I’m a senior in mechanical engineering graduating in May and I recently received an offer for a Spring 2027 mechanical engineering internship at a launch provider on a team working on satellites. Taking it would delay my graduation until at least Fall 2027. I’ve already completed two internships, one in manufacturing engineering and another in product development at an automotive supplier, and I have significant structural design and FEA experience through my university’s rocketry team. My goal is to work in aerospace mechanical design, ideally on structures, mechanisms, or flight hardware, but I don’t have any professional aerospace experience yet. I honestly don’t care much about delaying graduation, my main concern is whether taking this internship would meaningfully improve my chances of landing the kind of full-time engineering role I want, or whether I’d be better off graduating on time and applying with my current experience. Has anyone been in a similar position, and was delaying graduation worth it?

Heavier oil or grease might be more suitable in many applications but this is just a silly thing to say

I am in my 2nd year of university and my university requires us to get a work placement in 2nd, 3rd or 4th year and I wanted to ask about intresting feilds that pay well and don't feel like slavery (am located in the middle east)

I can picture myself writing the code of a mechatronics/robotics system or working with the modern predictive maintenance protocols. What are job titles I should aim for and what is a good advice for someone in my position.

Is it still possible to find competitive jobs after graduating without experience?

16 Upvotes

Hey everyone. Just wanted to ask this to everyone here. Is it still possible to find high-brow jobs such as Lockheed Martin even after graduating without anything but a degree? I was doomscrolling on LinkedIn (and also on here), and all I see is people accepting these roles at great companies such as Boeing and so on. I’ve never been at their level of success and it does make me sad but realistically is it still possible to achieve something great like them? I dont mean immediately, but perhaps in the span of 1-10 years of working less competitive jobs. I have an immense amount of ambition to do great things and would like to work one of those jobs one day
