Project Engineer, Data Center for AI / HPC high-density and liquid cooling builds
Data Center Headhunters recruits critical facilities, data center operations, construction and delivery, commissioning, power and cooling, and executive talent for colocation, hyperscale and enterprise sites. We research the market, contact working people and qualify a shortlist for your opening. No upfront fee. You pay only if you hire.
High-density AI and HPC halls change what a project engineer must track. Rack loads are heavier, cooling often involves liquid loops, and power and piping meet at the rack. The hire needs enough technical vocabulary to chase the right submittals and spot interface gaps between trades.
This is what we do all day: recruit data center professionals.
No postings. No stacks of resumes. No chasing. You interview a short list.
No upfront fee. You pay only if you hire.
No upfront fee. You pay only if you hire.
We offer a candidate replacement guarantee on standard search agreements. The applicable period and exact terms are set out in the signed client recruiting agreement.

What does this hire really come down to?
Decide how much liquid cooling exposure you need. A project engineer who coordinated direct-to-chip piping, coolant distribution units and flushing is rare. One who coordinated conventional chilled water may learn quickly if you pair them with a mechanical lead. Probe the power side.
Higher density means larger busway, heavier distribution and tighter tolerances. Ask what they know about how that changes submittal review and delivery sequencing.
Consider owner involvement. AI deployments often come with an owner who is still defining equipment, so expect late changes. The engineer must be comfortable running change logs against moving requirements.
What do we check before you see anyone?
Ask them to describe the piping interfaces between facility water and the cooling distribution at the rack, and who owned each side of the handoff. Have them explain how flushing, pressure testing and cleanliness records were tracked before coolant was introduced.

- Check how they dealt with owner-supplied compute hardware arriving on a schedule that did not match completion of the room.
Where do we find these candidates?
Search project engineers from conventional data center builds who have moved onto liquid or high-density halls, plus engineers from semiconductor and pharmaceutical process piping jobs. Mechanical contractor project engineers who handled clean piping systems and hydronic commissioning bring a useful base.

Which hiring mistakes should you avoid?
Do not accept a claim of liquid cooling experience without asking what part of the loop they handled. Do not overlook weight and structural coordination. Dense racks stress floors and routing. Do not assume the owner's design is final.

Your search in 3 steps
- Fix the technical floor
List the systems the person must understand, then decide which are essential and which can be learned.
- Ask for specifics and test change handling
Request details on a piping or power interface they personally tracked. Present a late owner change and ask how they would log, price and communicate it.
- Involve the mechanical lead
Have your mechanical lead judge whether the vocabulary is real.
Where power and water meet
Traditional halls keep mechanical and electrical largely separate until commissioning. High-density rooms bring them to the same rack, so a delay in one trade blocks another.
A good project engineer will draw that dependency map without being asked. Listen for whether they talk about trades colliding or only about documents.
Questions to put to the mechanical lead
Before the final round, give your mechanical lead the candidate's description of a liquid loop and ask whether it holds together. Check for correct order: fill, flush, pressure test, then commissioning with load.
Also ask the candidate what they would refuse to sign off. A project engineer who can name a cleanliness record or a pressure test report that must exist before coolant moves has watched real work, not brochures.
Adjacent experience worth a second look
Pharmaceutical and semiconductor piping teams treat cleanliness and documentation as law. If their project engineers can learn rack-level power quickly, they may serve you better than a conventional air-cooled hall veteran who has never seen a flushing record.

Questions
When might I see project engineers with real liquid cooling exposure?
We will not promise a date. The group who tracked coolant distribution units, flushing and pressure tests is small, so we will tell you early whether adjacent piping backgrounds could work. A realistic view comes after the first conversations.
Will a candidate stay after a counteroffer in this segment?
Demand is high, so employers counter fast. We ask whether the reason for listening, such as scope or a stalled project, is something their company can actually fix. Candidates leaving for scope are less likely to reverse.
Is relocation realistic for AI build sites in new regions?
Many sites are outside established markets, so relocation or rotation is common. Some candidates prefer short assignments. Tell us what support you offer.
How should I describe per diem when sites are remote?
Name the rotation, lodging, and per diem plainly in the first conversation. Candidates compare these closely, and surprises late in the process cost you the hire.
What makes a project engineer a fit for a design that keeps changing?
Calm under late owner change and willingness to keep a clean change log. Ask what they learned most recently about rack-level power or cooling. Someone who cannot name anything recent may not keep pace.
Who should see the fee terms before we start?
Whoever approves the engagement. We set terms out before work begins and can share the written version for review.
