I accepted the AWS DCO L3 in the midwest . I want you guys to help me help myself lol. I am from the south, i'm from Louisiana and lived in Texas. I know is obviously snow is a big difference, but i want to know if anyone else made the move like 16 hours away for a DCO job. I tried to get Texas and Georgia, but they didn't know how long i would be on the waitlist, I can't afford to wait because I was laid off from my last job and it's be hard to find work. I applied to over 800 jobs and this is my only yes, I have been unemployed for the last 15 months. There's no IT jobs in Louisiana and apparently when I Interview for other jobs, people want to do in person interviews... like bro i'm 9-10 hours away, tha's a hard ask especially if you have multiple rounds of interviews. I mention that so you guys understand my circumstances. My previous job I worked 7am-4pm, I was off weekends and holidays, and I was responsible for the IT infrastructure, I did that until I got laid off. I know at AWS is different so the shift at my location is 7am-5:30pm or 11:00-9:30 pm, and the schedule is front half Sunday-Wednesday. Back half is Wednesday-Saturday and all shifts follow 4 days on 3 days off rotation. Pay is $30.77 or 64k a yr, of course the $3k bouns that will be tax heavily lol. I am single and I have a dog, I do not have family or friends where I am going, so i'm asking has anyone had my experience in this? like did you do rover? bring your dog to doggy day care? I know a data center is not the place you can just leave on your lunch break to take your dog out lol. Do you meal prep and bring you lunch? how much food do you bring? How did you get use to a 10 hour shift? what kind of shoes do you wear so your feet don't hurt? Did you like the city you moved for? if not how fast did/can transfer? I would like to be a network engineer but idk how this job will help or if i can transfer inside to do that? I know a lot of people leave and go to google or microsoft, how do you like that better? any other tips and advice will be welcomed.

Hi i'm a student in a network associate degree in france and i want to get into data center industry but i really dont know wich country to target

Does anyone here work at Crusoe and can confirm if they allow secondary market sale for their rsu's with no limit ?

Appreciate the help, got reached out by recruiter for an interview , debating if I should interview . Thanks.

starting soon with mc dean as a critical environment technician, anyone with experience working with them have any insights?

hey everyone, i have my final loop interview next week for an L3 EOT position (2 interviews) at AWS. i’m fairly confident on the technical side but struggling with LP stories.
i have around a year of experience, internship and a trainee role, so i wasn’t involved in many complex tasks. i’ve prepared 10+ STAR stories but only feel confident about a few. the rest have pretty basic outcomes and not much measurable impact.
i really don’t want to miss this opportunity. anyone with a similar background who made it through the loop? how did you handle LP questions with limited experience?
tldr: L3 EOT loop next week, technical prep is good but struggling with strong STAR examples due to limited experience. looking for advice from people who’ve been through it.

I ask because I'm working with our local community college to build classes for data technicians. We've got a pretty good list with help from the local data center, but I figured I'd ask the wisdom of reddit since I can still make changes and it might help someone better succeed in their job.

What is the expected salary of Sr Engineer in AWS datacenter in Seattle?

I have masters with 8 years of experience with similar work experience, how do we know if the role is L5 or L6?

Note: This write-up is structured as a deterministic boundary specification (originally compiled for our CxA field checklists and AI agent ground-truth corpus, not casual marketing prose).

On site after site, project teams wheel 100 kW resistive air load banks into a whitespace designed for high-density liquid-cooled AI racks (like NVIDIA GB200 NVL72), heat up the room air, watch the CRAHs spin up, and sign off on 'Integrated Systems Testing (IST).'

In physical reality, if the thermal rejection path splits at the rack manifold (~75–85% liquid via the CDU, ~15–25% air via rear-door or perimeter CRAHs), your commissioning boundary must split at the manifold too.

What an Air Load Bank Never Tests on a Liquid-Cooled Row:

1. Hydraulic ΔP & Parallel Manifold Starvation: Heating room air leaves the secondary propylene glycol (PG25) loop stagnant or running through a wide-open bypass jumper. It never validates differential pressure ($\Delta P$) across parallel rack manifolds or checks whether the farthest rack from the CDU header is flow-starved.
2. CDU Proportional Control Valve Hunting: AI training workloads step from 10% idle to 100% TDP in milliseconds. Only a rack-mounted liquid load bank coupled to the blind-mate quick-disconnects (QDCs) forces the CDU's secondary pumps and primary 2-way control valves to respond to real return-water $\Delta T$ spikes without hunting.
3. Plate Heat Exchanger Approach Temperature at Design LPM/kW: You cannot verify the CDU heat exchanger's approach temperature ($T{\text{sec,supply}} - T{\text{pri,supply}}$) unless full thermal kilowatts are injected directly into the wetted secondary fluid stream at the exact design flow rate (e.g., 1.2 to 1.5 LPM/kW).
4. QDC Thermal Expansion & Seal Integrity: Cold hydrostatic pressure tests at Level 2/3 do not stress EPDM/FKM seals under cyclic thermal expansion ($25^{\circ\text{C}} \rightarrow 48^{\circ\text{C}$} return) at full pump head.

Minimum Field Acceptance Gates Before Signing L4/L5 IST:

• Boundary Separation: Reject any commissioning script that substitutes room-air sensible heat for wetted secondary-loop heat injection.
• 1-Second Telemetry: Polling BMS registers at 60-second intervals masks transient pressure spikes and flow drops during pump failover. Require $\le 1\text{ s}$ logging across supply/return headers.
• Strainer ΔP Pre/Post-Run: Record differential pressure across every CDU wye-strainer before and after the 4-hour full-load soak to catch construction debris flushing out of the manifolds.

Just moved here, and was wondering if there are any jobs in Security in the growing Data Center sector? Not sure if there is physical security, monitors, hybrid in these facilities... I don't see much advertised ... Thanks you.

Hi I would like to ask some advices on how to land a career here in Finland especially around Helsinki metropolitant regions. I’m currrently a student in Omnia pursuing ICT and I’m interested in the data centers as its getting quite popular and new here in Finland any tips or advice and/or help for someone like me that doesn’t have any professional experience yet in the industry of IT what projects or certificates i need to do or anything in general information i need to know to land a career wetherin data centers or in IT in general

I have an interview for Ridgeville, SC location. Any one from that location? Can you please share, how the environment is, how is the work load, what facilities are given at that location etc?

If you had the opportunity to work on the new Stargate project but you had to move your family halfway across the country on a supposed offer letter coming your way and you had less than a week notice to quit your current job to prepare to move without really anything in writing from HR but you already have an “in”, know your start date but still don’t see anything from talent acquisition, would you do it? This is my current situation.

Also, given the shape of the economy and how everything in the stock market is currently being propped up on all of this phantom revenue across all of the AI data centers going up, along with the metal shortages happening across various supply chains, oil, and tariff shipping constraints, I am genuinely worried about the longevity of this project despite billions being allocated into the expansion of it.

They said I have positive indicators to move me to the next round however they send this in the email. “we are currently waiting for a role to open that aligns with your specific profile.” Is this a rejection by Google or is it a realistic chance I can be matched and offered a job for the Data Center Technician role?

Hey everyone,

I'm looking for advice from people currently working in data centres, especially those familiar with Amazon/AWS operations.

I've received an offer for Rack Lifecycle Tech (L3) – Trainee at Amazon in India, with a package of approximately ₹10 LPA.

Currently, I'm working at a startup with exposure to full-stack development. My long-term goal is to grow into software engineering, backend development, and eventually AI/ML engineering.

From the job description, I understand that the Amazon role involves rack installation, fibre and copper cabling, connectivity testing, inventory management, documentation, and rack decommissioning.

I'm attracted to the opportunity to work at AWS and learn how large-scale data centres operate, but I'm trying to understand the reality of this role before making a decision.

I'd appreciate your insights on a few questions:

1. What does a typical shift look like for a Rack Lifecycle Tech?
2. How much of the work is physical installation and cabling versus troubleshooting, scripting, or automation?
3. What are the usual working hours, shift patterns, physical demands, and workload like?
4. What career progression is realistic from this role — for example, into network engineering, data-centre engineering, infrastructure automation, or software development?
5. Has anyone here moved from a rack technician or similar operations role into a software engineering position? If so, what helped you make that transition?

I'm not expecting this role to be a software engineering job. I just want to understand whether it offers a good long-term foundation or whether I would be better off continuing to build full-stack experience.

I'd especially appreciate honest, first-hand experiences from people who have worked in similar roles. Thanks!

What role can I progress into after dct?

Other than being a manager.

Hey, so i'm not sure which certification to go with here. Its provided by Amazon career choice and the amazon one upon completion gives you 2 comptia certs them being a+ and network+, starting amazon wage $27/hr and the 2nd one starts at $33/hr but would amazon be the better option long term?

Hey everyone,

Wanted to share a unique perspective from inside one of our real-device cloud testing racks, taken with an ultra-wide angle lens while running manual device triage and hardware validation.

While traditional enterprise data centers focus on blade servers, high-density compute nodes, and 42U rack-scale network switching, building infrastructure for mobile hardware testing introduces a completely different set of physical density and engineering challenges:

• Thermal Management & Airflow: Stacking dozens of active smartphones and tablets in close proximity creates severe localized thermal hotspots. Passive ambient cooling isn't enough when lithium-ion batteries are continuously under load, requiring targeted high-CFM chassis fan arrays to prevent thermal throttling and battery swelling.
• Power Delivery Infrastructure: Managing power delivery across hundreds of individual DC endpoints (USB-PD / 5V-9V delivery) without tripping PDU thresholds or introducing ground loops requires specialized, metered USB host hubs rather than standard AC power strips.
• Host-to-Device Topology: Unlike standard rack servers with dedicated IPMI/BMC, physical mobile device farms rely on dense USB/Lightning topologies connecting back to host runner servers for ADB (Android Debug Bridge) and WDA (WebDriverAgent) control loops.
• Structural Density & Cable Management: Framing metal chassis to maximize device density per rack unit while maintaining clear serviceability for physical maintenance (replacing degraded cables, swapping faulty devices, and isolating RF interference) is a constant balancing act.

Respect to all the infrastructure teams managing specialized physical hardware farms alongside standard rack-mount gear!

Curious to hear if anyone else here manages non-standard hardware density or specialized device labs in their facilities? How do you handle battery thermal monitoring and power distribution at scale?

After 5 interviewer no-shows, I finally finished all 3 rounds for the DCT position. Got an email back from my recruiter about two hours after my last interview, saying he'd like to "schedule a call to discuss the outcome". I've been going through this process for like, two months now. Does this mean a yes or no? Not exactly thrilled about having to wait four days for a fifteen minute phone call,

Hey guys, (im from mexico)

I've been working as an electrician in hospital construction for 13 years, and I'm currently just one semester away from finishing my Systems Engineering degree. A few years ago, I also took a Cisco CCNA course for a class, though I never actually paid for the cert exam.

On the electrical side, I have a ton of hands-on experience installing, troubleshooting, and doing PMs/corrective maintenance on:

LP gas, natural gas, and diesel generators

ATS (Automatic Transfer Switches)

Voltage regulators and UPS

Isolated power panels

I'm really trying to transition into data centers. Given my background, what should I study or focus on next? I already understand how critical these environments are. In ORs and ICUs, if the power fails, someone dies. In a data center, if the power fails, companies lose millions.

Any advice on certifications or specific roles (maybe Critical Facilities?) I should look into would be awesome. Thanks!

Thank you again for taking the time to speak with me and the interview team. The team found enough positive indicators to move you to next steps; however, we are currently waiting for a role to open that aligns with your specific profile. 

Deployment lead is for an established hyperscaler. Lead Hardware tech role offers break fix experience on the newest racks from day 0 to prod. Which one seems like the better career choice. The margin in pay is too small over 5 years to factor in.

Hey everyone, I passed my Google Data Center Technician II interviews about 3 weeks ago and now im waiting to see if a team picks me up.

My recruiter has emailed me saying I did very well, my scores were strong, and my skillset is highly competitive. He also said people getting selected ahead of me have direct data center experience with companies like AWS, Meta, or IBM. He clarified that this was his observation and he doesnt have access to the hiring managers internal discussions.

I currently work in IT doing hardware troubleshooting, workstation deployments, networking support and some server installations, but I havent worked in an actual data center. I studied pretty hard for these interviews, so passing felt great. Waiting afterwards has been discouraging though, especially when I keep seeing postings for the same location.

I have a preferred location but recently opened up to another site too. My recruiter is still responding and says I’m actively being considered, so I know it isn’t a rejection. I just dont really know what to expect from here.
For anyone who’s been in this situation, how long did you wait after passing before getting a fit call or an offer? Did anyone get hired without previous data center experience after being passed over for other candidates?

Would appreciate hearing how it actually went for you, even if it didn’t end in an offer.

Thank you all!
