About the role

Key responsibilities & impact

Deploy and commission cooling and mechanical systems at data center sites, running equipment startup, functional testing, performance verification, and acceptance testing through to live handover.
Support operational reliability of deployed cooling infrastructure, responding to thermal events and equipment failures on live sites and implementing fixes that prevent recurrence.
Resolve field conflicts between installation conditions and mechanical system requirements during commissioning, keeping deployments on schedule.
Monitor and validate thermal performance of cooling systems under live AI compute load, flagging degradation and driving corrective action before it affects availability.
Contribute to mechanical commissioning checklists, startup procedures, and maintenance run books that improve consistency across future deployments.

Requirements

What you’ll need

You hold a bachelor's degree in Mechanical Engineering or a related field.
You've supported or led mechanical commissioning on data centers or high-density facilities, with hands-on accountability through equipment startup and live acceptance.
You can identify installation errors, diagnose performance shortfalls, and support corrective action on chilled water, CDU, or direct liquid cooling systems at the operational level.
You've worked effectively alongside contractors and commissioning agents on active sites while holding the line on quality.
You can travel to deployment and operations sites up to 50 percent of the time.
Bonus: Professional Engineer (PE) license, or active pursuit of licensure. Direct liquid cooling or CDU commissioning and operational experience at AI-class rack densities. Familiarity with thermal monitoring systems, CMMS platforms, and predictive maintenance practices. Proficiency in CFD tools used for operational troubleshooting and thermal validation.
