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.

- Energy Efficiency Engineer (PUE)
What does this hire really come down to?
An energy efficiency engineer analyzes where power goes between the utility meter and the IT load. They study cooling plant performance, airflow management, UPS losses, setpoints and metering quality, then propose and test changes. They do not own the operating procedures or approve changes on live systems unless the facility assigns that authority.
The key judgment is operating conditions. Some engineers have worked on a live facility and know that any change must pass change management, vendor review and customer notice. Others have worked in design, where efficiency is a modeling exercise. Both are useful, but the first can implement and the second can recommend.
Adjacent seats include the critical facilities engineer, who runs the plant, and the mechanical engineer, who designs it. The efficiency engineer sits between them and needs credibility with both. Ask whether their recommendations were adopted and what happened afterward.
What do we check before you see anyone?
Ask how they measured PUE and what meter points they used. Poor metering gives misleading results, and good candidates know it. Ask for one change they made and the risk they managed. Look for rollback plans and customer communication. Ask how they separated seasonal effects from real improvements.

- Ask how they separated seasonal effects from real improvements. Weather swings can fake a gain.
- Ask what they did when operations pushed back. Efficiency work fails when the operators do not trust it.
Where do we find these candidates?
We look at critical facilities engineers who have taken on optimization projects, because they understand live risk. Mechanical consulting engineers who specialize in cooling and energy modeling bring analytic depth. Energy service companies and building performance teams supply engineers experienced in measurement and verification, though some need time to adapt to uptime constraints.

Which hiring mistakes should you avoid?
Do not hire a modeler to run live changes. Models do not carry the same consequences as a cooling event. Do not chase a PUE figure without checking how it is defined. Different sites measure at different points. Do not overlook water use.

Your search in 3 steps
- Define the target
We confirm whether you want a measurement lead, an implementer, or a designer for new builds.
- Check live exposure
We screen for experience making changes in running facilities under change control.
- Probe the evidence and present options
Candidates explain how they measured results and how they dealt with disagreement. You receive a small slate with notes on analytic and operational strengths.
Interview questions
Ask them to describe a measurement they distrusted and how they corrected it. This reveals method, not just results.
Ask what change they would refuse to make on a live floor. Good engineers know their limits.
Ask how they would split a cooling plant improvement into stages so each can be reversed. Staged changes with clear measurement points are far safer than one large adjustment during a heat wave.
Ask how they treat partial load. Many facilities run well below design capacity for years, and efficiency at low load is a different problem from efficiency at full load.
Ask which of their recommendations went unused and why. Candidates who can name one and describe the reason show humility and judgment, and tend to work better with operators.
Ask how they would present a saving to a finance team that wants it in dollars. A careful engineer states the assumptions behind the estimate and what could shrink it.
Where the role fits in the team
Decide who the engineer reports to. Under operations they will implement more and study less. Under engineering they will study more, and changes will depend on persuading the operators.
Also settle who owns the meters. If the engineer must ask three departments to fix a sensor, progress will stall, whatever their talent.

Questions
How quickly can we meet engineers with live PUE improvement experience?
Candidates who changed settings on running plants are fewer than modelers, so we say which side is thinner after scoping, without quoting a number. Asking for live change-control experience narrows it further.
Will an engineer whose savings are credited to them get a counter?
They might, since visible savings give leadership a reason to keep someone. We ask what the person wants next and share that.
Does PUE work require being on the floor?
Walking the chillers and checking meters on site matters. A remote analyst can handle some of the work but not the plant changes.
Who pays for visits across multiple halls or sites?
Multi-site efficiency work requires repeated trips. State lodging and daily allowance in the offer.
Should the engineer come from design or from operations?
A designer fits a new hall where efficiency is built in. An operator fits a running hall where change control constrains each step.
If we also want chilled water and electrical loss work, does the search change?
Spanning cooling and power losses needs broader experience than either alone, so tell us whether one person must cover both. One person rarely excels at both, so a pair of roles may serve you better.
