How to be a data center technician

4 Upvotes

Hi there! I would like to ask some advice and help on how to be a DCT without any experience at all.

I’m 20 currently studying ICT vocational school in Finland and I want to be a DCT because there will be a data center near our area and i want to grab the opportunity and start my career as early as possible in tech.
I’m also starting studying for CCNA because I heard its the gold standard of certs in the dct field.

What things i should focus first and what kind of projects i can do that can help me understand how a data center works?

And lastly if just if i got an interview in a dct internship position what advice can you give me to prepare for the interview.

Received Amazon AWS Data Centre Linux & HW Engineer Online Assessment – Need Preparation Advice

2 Upvotes

Hi everyone,

I recently received an online assessment invitation from Amazon for the Data Centre Linux & HW Engineer, Data Center Operations role in Hyderabad (Job ID: 10498164).

This is my first Amazon assessment, and I want to prepare properly before starting it. The email says the assessment takes around 40+ minutes and needs to be completed within two weeks.

My background:

  • ~1 year of production IT infrastructure/support experience
  • Linux and Windows troubleshooting
  • RAM replacement and hardware troubleshooting
  • PC/equipment rack installation and router mounting
  • Network cabling and troubleshooting
  • TCP/IP, DNS, DHCP, VLAN basics
  • AWS EC2, VPC, ALB, CloudWatch
  • Bash/PowerShell
  • Active Directory
  • Zabbix monitoring

I'd really appreciate advice from anyone who has recently taken the AWS/Amazon Data Center Operations / Linux & Hardware assessment, especially:

  1. What sections or types of questions should I expect?
  2. Is it mainly technical questions, work scenarios, work-style questions, or a combination?
  3. Which topics should I prioritize — Linux, hardware, networking, troubleshooting, AWS, or Amazon Leadership Principles?
  4. How difficult is the assessment compared with the actual technical interview?
  5. How would you recommend preparing in the few days before taking it?
  6. Are there any common mistakes I should avoid?

I'm not looking for actual assessment questions or answers, just recent candidate experiences and preparation advice.

Thanks in advance to anyone who can share their experience!

How are you actually handling coolant chemistry monitoring on your DLC loops?

0 Upvotes

Curious how people are doing this in practise, because I keep going back and forth on it.

We've got a growing D2C footprint (PG25 secondary loops, fairly standard CDUs) and right now the fluid program is the textbook tiered thing: heavy sampling at commissioning, then weekly, then quarterly pH/conductivity/glycol checks, plus an annual lab panel for inhibitor reserve, metals and bio. It works, but it's episodic, and the gaps between samples make me a little nervous given what's sitting downstream of these loops now.

I'm wondering, is anyone running continuous/inline chemistry monitoring on the secondary loop, or is it still sampling plus scheduled fluid changes for basically everyone?

I originally come from the chemistry inndustry where inline monitoring is a standard and keep wondering:

  • Is inline chemistry monitoring actually a thing people deploy yet, or is it still lab-and-cadence in the real world?
  • If you've had a chemistry-related scare (pH crash, corrosion products, bio), did routine sampling catch it in time, or did you find out the hard way?
  • Is continuous monitoring worth the hassle, or is a sensible replacement cadence genuinely fine for a well-built loop?

Just trying to sanity-check our approach, the industry seems a bit all over at the moment. War stories are welcome ;)

Starting Steps into a Data Center Career

2 Upvotes

My background is in mechanical engineering, with 18 years of experience across building services, systems commissioning, sustainability, and green building. United Arab Emirates.

I’m now looking to transition into the data center sector, ideally leveraging my mechanical, MEP, and commissioning experience rather than positioning myself primarily within sustainability.

What would be the best starting point for making this transition, and which certification would provide the strongest foundation and industry recognition?

I’m aware of the Uptime Institute sustainability-related certifications, but I’m specifically looking to broaden my profile beyond the sustainability label and move toward data center engineering, commissioning, design, or critical infrastructure.

Wait for Google, or take a guaranteed AWS spot?

10 Upvotes

I interviewed with Google for a DCT I position almost a week ago, and have been refreshing my email since. I’ve read that some people get their results back in a couple of days, while others have waited months to hear back.

I currently work as an IT Technician at an Amazon fulfillment center (where your orders are packaged), and my now former manager left our team to go to a new AWS site being built 100 miles away. He has since sent me a DM, asking if I was interested in going over there, and to let him know if I am.

He has already helped others on our team transfer to the new AWS data center, and I guess I could be next. So now I ask, should I go ahead and join AWS, or hold out for Google?

Looking for AWS DCO Recruiter

3 Upvotes

Hey everyone,

I've been working as a DCO green badge at an AWS DC in Ashburn for about 4.5 months now. Bad news is my contract's not getting extended; basically a hiring freeze thing where they're prioritizing new hire blue badges over converting contractors right now.

I've been working on a decent variety of break-fix and networking tickets in that time and some projects, so I've got some solid hands-on experience.

Good news is my manager's actually got my back said he'd vouch for me if I can land an opening at another cluster, and he'd help get me transferred over if something opens up. Already threw in an application for a DCO role in Sterling, but figured I'd ask here too. If anyone's an AWS recruiter in NOVA region, works in DC ops, or knows someone who does, I'd love a point of contact.

Appreciate any help, thanks.

Battery backup vs. flywheel UPS — is anyone actually running flywheels in a small-to-mid DC anymore, or did lithium just win?

10 Upvotes

We are currently refreshing UPS for ~150kW facility; however, despite the vendor’s insistence on using flywheel systems due to the lack of battery room and the absence of the need to replace VRLA every 3-5 years, I have found that the specifications sheet for flywheel systems lists ride-through time of between 15 seconds and 30 seconds, which is something we can only reliably work with if we are positive that our generator always starts and operates without problem. Battery technology, on the other hand, offers ride-through times of 5-10+ minutes and is generally much cheaper.

My question is whether flywheel is obsolete in today’s market or whether it really has advantages over existing technologies that I was not presented with by the vendor.

Anyone working AWS DCEO in Spain? Questions before I take the leap

8 Upvotes

Anyone working at the AWS data centre in Zaragoza, Spain? Questions about EOT life there
I’m in process for an Engineering Operations Technician role at the Zaragoza site and I’d like to hear from people actually working in AWS DCEO, ideally in Spain or elsewhere in EMEA.

Background: 9 years in industrial maintenance at a manufacturing plant, robotics, CNC and PLC, four-shift rotation. No data centre experience yet, so I’m coming in from the outside.
A few things I can’t find reliable answers to:

1. Day to day. How much of the work is planned preventive versus reactive? Is most of the PM done in-house or by vendors with you supervising?

2. Qualification process. How long does it take before you’re signed off to work unsupervised on critical systems, and what does that training actually look like?

3. Shift pattern. I’ve been told it’s an 8-week loop rotating central, days, evenings and nights every two weeks. Is that the standard EMEA pattern? How does the on-call work alongside it?

4. Progression. Realistically, how long from EOT to the next level? Does moving into commissioning or controls from operations actually happen, or is it mostly external hires?

5. Compensation structure. Not asking anyone to post numbers. I’d just like to understand what makes up the package for a technician in Europe: is there an equity component at this level, and how much do shift allowances typically weigh against base?

6. Site-specific. Anyone at Zaragoza or another newly built site: what’s it like working somewhere still expanding? Does that create real internal opportunities or is it just more of the same work?

Happy to hear the bad parts too. I’d rather know now.

I currently work at a commercial hvac company and have been for 3 years. We do work at Microsoft data center and it seems like a cool job to have as a critical environment technician. Apparently Microsoft uses ATS for the job applications. Is it worth my time to keep applying and hope to get in someday or just keep doing commercial hvac? I’ve applied once already and got denied but applied again a few weeks ago. Just waiting to hear back now. Let me know your experience as a critical environment technician! Any responses will be helpful.

Changing shifts as AWS DCT? Guaranteed?

3 Upvotes

Hi all,

On my wife's account, but I'm working with a AWS recruiter for a DCT position, and I was told there aren't any open spots at my local DC, however, their might be some opening up in the next few weeks.

Unfortunately, the recruiter said I'd have to be willing to take any shift if that's what offered, e.g. night shift, but that it's guaranteed I could change shifts after three months.

I'm not so sure it's 'guaranteed' I can do that, but that's what the recruiter said.

For those of you with AWS, what is the truth to this?

Wondering if misusing my engineering degree

0 Upvotes

I’m a mechanical engineer, new grad one year out of college. It was really difficult to get a traditional engineer job. After 6 months I got into Electrical Commissioning but my first job pigeonholed me into Qa/Qc for 8 months at a 140MW DC. I did really well, got a raise few months in but I felt overqualified.

I just took a new job as a real Cx Agent making good six figs and doing well at my job. But constant travel and the specter of working long 12+ hours days is worrying me.

I’m wondering if I’m making a mistake career wise, most Cx agents I meet aren’t degree holders and unsure if I could transfer these skills to a regular engineering office job.

Any advice to young professionals in this industry?

Edit: With 60hrs week I make equivalent to $30ish/hr. It is very good money rn for loans, but afterwards career wise I’m unsure.
