What does this hire really come down to?
These desks sit at the line between facilities and technology. The network engineer designs and operates the connections. The IT operations lead runs what is installed in the room. The cloud infrastructure engineer builds the software defined layer. The AI infrastructure engineer deals with dense compute, accelerator clusters, and the fabric tying them together.
A single title in a job post can mean any of those. The central hiring question is who owns what at the edge of the rack. Power and cooling usually belong to critical facilities. Cabling often belongs to a contractor. The IT team owns configuration, inventory, and change. If your posting hides that, you will attract candidates who assume a different split.
AI builds add another variable. Racks draw far more power and may use liquid cooling, so IT staff need to work comfortably alongside facilities engineers and respect their lockout rules. Ask whether the person has worked with that constraint or only with ordinary enterprise racks.
What do we check before you see anyone?
- Request one real incident from each candidate and have them name who else was involved. People who describe only their own heroics often did not coordinate well.
- Confirm what the candidate personally configured versus what they supervised or reviewed.
- Check credentials for what they prove: BICSI covers cabling work and RCDD is design, Uptime AOS covers operations management, and CDCP is foundational training. None replaces role evidence.
Where do we find these candidates?
Network seats draw from carriers, internet exchanges, enterprise networking, and service provider backbones. IT operations seats draw from colocation floors, managed hosting, and large enterprise server rooms. AI infrastructure candidates come from high performance computing, research clusters, and cloud GPU teams.
Contractors moving to direct roles are a legitimate source, provided you ask who owned the outcomes on their last assignment.
Which hiring mistakes should you avoid?
Do not write one posting for a role that mixes network design, floor operations, and automation. The market cannot offer all three in one person at your price. Do not overvalue brand names and undervaluing the scale and conditions of the work.

How the search runs
Clarify the seat
Write down the owned systems, the boundaries with facilities, and the pager obligations before posting.
Choose the right desk
Match the opening to the nearest of network, operations, cloud, or AI infrastructure, and keep adjacent titles out of the job text.
Screen on scenarios
Use real failures and change problems so candidates reveal habits rather than recite tools.
Decide offers with the facts
Compare candidates on scope and conditions, then discuss compensation and start dates openly.
Interview questions
Network: How would you isolate a fault between two sites when monitoring says both ends are healthy? A strong answer starts with what changed, names the tests in order, and says who else gets pulled in. A weak one jumps to replacing hardware.
Floor operations: What do you do when a customer demands an urgent change outside your window? Good answers describe an approval path and a refusal that was explained, not a heroic exception.
Cloud: How would you recover from a deleted network route in production? Listen for state files, review history, and a rollback they have actually used.
AI infrastructure: What changes in a rack design when power density rises, and how do you work with the mechanical team? Look for respect for lockout rules and a specific example of a mistake.
What the answers show
Strong candidates admit uncertainty, name collaborators, and describe the failure first. Weak ones recite tool names and describe outcomes without cause.
Questions
How should we think about shortlist timing across these desks?
Timing follows how precisely you define the seat and how many candidates will accept your location. AI cluster and network design pools are narrower than general floor operations. We report on market response and do not commit to a date.
How do we handle counteroffers for people who know our network or cluster?
Employers tend to counter strongly for them. Ask candidates early what would keep them, and respond quickly once an offer is out.
Will these candidates move?
Network and cloud staff often want hybrid or remote terms, while floor operations and cluster builds usually need local presence. Decide what is truly required on site and say so.
Does travel apply to these roles?
Some, especially during site turn-ups, migrations, or cluster deployments. State expected frequency and per diem rules upfront so candidates compare fairly.
What if a candidate fits two of these desks?
Choose by which responsibilities you need first and note what you would give up. A strong network person who wants floor work may need support and a defined growth path.
How do search fees work?
The terms are in the agreement signed before work begins. Our team can explain how they apply to the seat you have in mind.
