Lead Mechanical Engineer, Deployment Engineering

Role Scope

• Lead end-to-end deployment and commissioning of mechanical and cooling systems across concurrent sites, from pre-deployment readiness through live handover to operations.
• Own operational reliability of cooling infrastructure across the live fleet, diagnosing thermal performance issues and implementing fixes that hold at scale.
• Build and maintain mechanical commissioning standards, acceptance test procedures, and runbooks for cooling systems (chillers, CDUs, direct liquid cooling) that site teams run independently.
• Serve as the on-site technical authority through equipment startup, performance validation, and load testing, resolving field failures before they delay handover.
• Set and enforce mechanical reliability standards across the portfolio: preventive maintenance thresholds, redundancy validation, and performance benchmarks under live AI load.

Requirements

• Bachelor's degree in Mechanical Engineering or a related field.
• Owned field deployment and commissioning of mechanical systems on data centers or high-density mission-critical facilities.
• Commissioned and troubleshot cooling systems (chilled water, CDUs, or direct liquid cooling) on live or commissioning-phase infrastructure.
• Built commissioning standards, acceptance test procedures, and maintenance runbooks that hold up at a portfolio level.
• Diagnosed and resolved mechanical failures and thermal performance issues on live infrastructure under time pressure.
• Mentored mechanical engineers in the field and built their ability to commission independently.
• Ability to travel to deployment and operations sites up to 50 percent of the time.

Nice-to-Haves

• Professional Engineer (PE) license.
• Direct-to-chip or liquid cooling operational experience at AI-class rack densities.
• Experience building or leading a mechanical commissioning or reliability program across multiple concurrent sites.
• Familiarity with CMMS platforms, predictive maintenance tools, and thermal monitoring systems.
• Proficiency in CFD tools (6SigmaET, Icepak) for operational troubleshooting and thermal validation.
