You pay only if you hire.
You are hiring someone to stand next to a coolant distribution unit and decide whether it is ready to carry load, and a title that says liquid cooling will not tell you whether they have actually done that.
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.

- Liquid Cooling Field Service Engineer (CDU)
What does this hire really come down to?
This seat sits between the factory and the white space. The engineer services the CDU itself: pumps, heat exchangers, valves, sensors and controls. They do not own the facility water plant upstream or the rack manifolds downstream, and the best ones know exactly where their authority stops and who answers the phone on the other side.
The tradeoff is usually fluid handling against controls fluency. Some people have flushed and filled loops for years but cannot read a control sequence. Others tune setpoints well and have never managed water chemistry or a leak at a quick disconnect. Decide which failure your units are more likely to produce before we search.
A field technician follows the manufacturer's procedure. A field service engineer diagnoses when the procedure does not fit, writes up the cause for the manufacturer, and signs off the unit for the commissioning team. If your own engineering group will do the diagnosis, you need a technician, not this title.
What do we check before you see anyone?
Ask what they did the last time a pressure or flow reading disagreed with the design. A real answer names the instruments they distrusted first. Check refrigerant exposure honestly. EPA Section 608 matters only if the unit carries a chiller circuit, and the card is issued by an approved certifying organization, not by EPA.
- Ask them to walk through a fill and flush: what fluid, how it was verified clean, how air was removed, and what they recorded before handing over. Vague answers usually mean they assisted rather than led.

- Ask what they will not touch without the facility's lockout, and who they called to get it. Facility water and electrical isolation belong to other people.
Where do we find these candidates?
We look first at equipment manufacturer service organizations that support pumped liquid loops, because their people have seen units fail in the field rather than on a bench. Industrial process cooling and large chiller service backgrounds convert well when the person has worked glycol or treated water loops.

- Industrial process cooling and large chiller service backgrounds convert well when the person has worked glycol or treated water loops. Pure air-side HVAC people usually need time on fluid chemistry.
- Hospital and semiconductor plant utility technicians sometimes bring excellent loop discipline, though they may be new to customer-facing handover paperwork.
Which hiring mistakes should you avoid?
Do not hire on rack-level liquid cooling familiarity when the work is at the CDU and plant interface. Do not expect one person to cover both service calls and new-unit startups without checking whether they can travel and still answer an outage.

Your search in 3 steps
- Define the boundary
We settle which equipment the engineer owns, which belongs to the facility team, and who authorizes isolation, so the search targets the right history.
- Screen on a real loop
Early conversations center on a specific fill, flush or fault the person handled, with details only someone present would know.
- Test the handover and compare
We ask how they documented work for the next party, because a poor record leaves your commissioning team guessing. You see a short list with the fluids-versus-controls balance of each person stated plainly.
Before you write the offer
Be clear about response duty. If the engineer carries an on-call phone for customers with live liquid loads, say so now, along with who backs them up. Engineers who have lived with that phone will ask, and those who have not usually underestimate it.

Questions
How quickly can you present a shortlist for this seat?
Timing depends on how closely your CDU platform matches what candidates have already serviced. Once we have the equipment and the travel expectation, we can tell you early whether the pool is narrow.
What happens if this engineer receives a counteroffer?
Manufacturer service staff are often counteroffered because their employer knows the cost of losing them. We raise it during screening and ask what would genuinely change their mind, so you hear risk before an offer.
Will candidates relocate for this role?
Field service people often live near an airport rather than near a plant, so relocation may not be necessary. If you need a resident engineer at one campus, say so early because it changes who will consider the role.
How should we frame travel and per diem?
State the expected share of nights away and how per diem is paid before the first conversation. Engineers compare these terms closely, and surprises late in the process cost you the offer.
How do we judge fit with our unit design?
Ask for one failure they diagnosed on a loop similar to yours. Familiarity with your pumps or controls platform helps, but diagnostic habits transfer better than brand names.
Should the engineer's pay reflect pump and controls work or only loop service?
Tell us which tasks sit in the job, because an engineer who also diagnoses control sequences commands a different range than one who flushes and fills. Share your pay range up front and we will say whether it fits the pool for that mix. The fee terms are in the written agreement.
