Lead Mechanical Engineer, Deployment Engineering

About the role

The Deployment Engineering Team at Fluidstack is responsible for leading end-to-end deployment and commissioning of mechanical and cooling systems across concurrent sites. This role involves owning the operational reliability of cooling infrastructure at scale, diagnosing and resolving thermal performance issues, and setting and enforcing mechanical reliability standards.

Responsibilities

• 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

• You hold a bachelor's degree in Mechanical Engineering or a related field.
• You've owned field deployment and commissioning of mechanical systems on data centers or high-density mission-critical facilities.
• You've commissioned and troubleshot cooling systems (chillers, CDUs, or direct liquid cooling) on live or commissioning-phase infrastructure.
• You've built commissioning standards, acceptance test procedures, and maintenance runbooks that hold up at a portfolio level.
• You've diagnosed and resolved mechanical failures and thermal performance issues on live infrastructure under time pressure.
• You've mentored mechanical engineers in the field and built their ability to commission independently.
• You can travel to deployment and operations sites up to 50 percent of the time.

Qualifications

• Bonus: 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.

Skills

• Strong understanding of mechanical and cooling systems in data center environments.
• Experience with commissioning and troubleshooting of chillers, CDUs, and direct liquid cooling systems.
• Ability to set and enforce mechanical reliability standards at scale.
• Knowledge of CMMS platforms, predictive maintenance tools, and thermal monitoring systems.
• Proficiency in CFD tools for operational troubleshooting and thermal validation.

Benefits

• Competitive compensation range of $300,000 - $340,000 per year, depending on experience, skills, qualifications, and location.
• Offers equity in the form of stock options.
• Fluidstack is an Equal Employment Opportunity Employer.
• We are committed to pay equity and transparency.
• Fluidstack will consider for employment qualified applicants with arrest and conviction records pursuant to applicable law.
