Commissioning Manager for Brownfield conversions and retrofits
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.
Commissioning a retrofit means proving new equipment inside a building that is already serving load or about to. The commissioning manager here spends as much time on isolation plans, method statements and rollback options as on test scripts, because the existing system is the risk.
This is what we do all day: recruit data center professionals.
No upfront fee. You pay only if you hire.

What does this hire really come down to?
The manager owns the commissioning plan and its interaction with the operating facility. They do not authorise outages or switching, which belong to the owner's operations and the site's switching authority, but they must plan around those decisions.
The team often includes the owner's own technicians, who know the building better than anyone on the project. A manager who ignores that knowledge will find out at the worst moment.
The difference from a new build manager is the baseline problem: nobody may have recorded how the old system actually behaves, so before and after evidence has to be created.
What do we check before you see anyone?
Ask how they establish a baseline on existing equipment that lacks reliable documentation, and what they do when drawings disagree with the field. Have them describe a tie in or cutover they planned, including the fallback if a test failed halfway through.

How a search runs
How does The Six-Step Search work?
We use executive-search discipline for technical, frontline and leadership assignments. That means understanding the work, researching the right market and holding meaningful conversations before recommending an introduction. The questions change with the assignment. A shortlist is an outcome of that judgment, not the whole service.
- 01
Search Calibration
We agree what the person must accomplish and what they will actually own. Construction, commissioning and live operations need different questions. We clarify systems, site type, scale, decision authority, reporting lines and the team around the hire.
- 02
Market Mapping
We research comparable sites, projects and teams, then consider adjacent backgrounds where the experience could transfer. A matching title is a starting point, not evidence that someone has handled the same responsibility.
- 03
Professional Contact Intelligence
Contact research helps us approach relevant people appropriately. It enables the search; it is not the product. Public records can be incomplete or out of date, so employment history and responsibility remain questions to discuss and confirm where appropriate.
- 04
Persistent Personalized Outreach
We explain the actual work and why the opportunity may be relevant, then follow up thoughtfully and respectfully. We listen to whether a move makes sense for that person rather than treating a response as proof of interest or fit.
- 05
Live Candidate Qualification
We ask about work personally owned, decisions made and what happened when a plan went wrong. We discuss motivation and practical terms: compensation, shifts, travel, per diem where relevant, availability and authority. We distinguish the candidate's account from anything independently confirmed.
- 06
Candidate Intelligence and Process Support
You receive a reasoned brief: why the person may fit, supporting examples, uncertainties and useful interview questions. We agree which credentials, references or other checks are appropriate and who will complete them. We stay involved through feedback, offer discussions and the start, rather than stopping at an introduction.
Where do we find these candidates?
- Commissioning leads from retrofit and upgrade programmes in occupied buildings, where windows and rollback matter more than speed.
- Facility engineering managers who have supported upgrades from the owner side and moved into independent commissioning.
- Controls and building automation commissioning backgrounds, who often meet old and new systems side by side.
Which hiring mistakes should you avoid?
Do not hire someone whose experience is all greenfield and who has never had to rescue a failed cutover. Name the switching authority and approval path to candidates, then discovering the manager expected to lead those decisions. Do not underestimate documentation gaps.
- Hiring someone whose experience is all greenfield and who has never had to rescue a failed cutover.
- Failing to name the switching authority and approval path to candidates, then discovering the manager expected to lead those decisions.
- Underestimating documentation gaps. A retrofit with no record of the existing plant needs a discovery phase.
Questions we settle before outreach
- Understand the live constraints
We learn which systems stay online, which windows exist and who approves work.
- Check documentation quality and screen on cutover experience
You tell us what drawings and records exist so we find someone who can cope with gaps. We ask for specific tie ins, rollbacks and surprises, and what changed afterwards.
- Present candidates
You receive notes on live site exposure and any gaps in new build or controls knowledge.
Planning around a facility that is already working
A retrofit manager must treat every test as a possible outage. Ask them to describe how they would verify a replacement chiller or switchboard without losing redundancy on the loads that remain, including which path carries the facility during the test.
Listen for rollback thinking. They should be able to say, without prompting, what they would do if the new equipment failed its first test while the old equipment was already isolated.
Records and the operator relationship
Ask what they did when the building log, the drawings and the operators disagreed. Experienced managers will describe trusting the operator's memory but verifying it, and will have recorded the discrepancy for the next team.
What to tell candidates up front
Say which operator approvals gate each window, how many outages the plan allows and whether the owner's staff will be in the room. People who handle live upgrades will decide quickly whether the constraints suit them.

Questions
How early can we see managers who have handled occupied upgrades?
It depends on how live your site is and how much owner side experience you need. After intake we can give a candid view without quoting a number.
Might the manager's current owner or contractor counter at the time of offer?
They are common for people running live upgrades because their employers depend on them. We explore motivation early and discuss timing around any open cutover.
Will a retrofit manager move for work at an existing site?
Because retrofit work stays tied to one facility, candidates ask how long it lasts before relocating. A defined multi phase programme attracts more movers than open ended support.
Is the retrofit manager expected on site through every cutover?
Cutover nights and early morning windows may require presence beyond ordinary hours. Describe that honestly, and candidates will tell you whether lodging nearby or a short rotation suits them.
How can we judge fit with an operator who knows the building better than the project team?
Look for someone who respects the operator's judgment and asks before touching anything. Ask them how they handled a disagreement with a technician who knew the plant.
What arrangement might need discussion for an interim manager?
We agree the terms in writing before any outreach. If the site might need a short interim hire before a permanent manager starts, mention it so we can explain how that would sit with the fee.
