Full Job Description
Mechanical Engineer, Deployment Engineering

The Deployment Engineering Team

Examples of key problems the team is working on
  • Turn 50GW+ of design into 50GW+ of built, running infrastructure. The Design team sets the blueprint. This team is where it survives contact with a live construction schedule and becomes a real site.
  • Close the gap between engineering-complete and operations-ready. A design that passes review still has to survive commissioning, integration, and energization, and that gap is where deployment work lives.
  • Make the tenth site faster and cleaner than the first. Every deployment feeds field learnings back into the standards, so a one-off fight at one site becomes a repeatable playbook at the next.
  • Hand off infrastructure that's reliable from the moment it goes live. AI compute workloads don't tolerate a shaky handover, so what this team commissions has to run right the day operations takes over.


Role Scope
  • 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.


What We're Looking For

The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
  • 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.


Compensation: $200,000 - $250,000 per year, depending on experience, skills, qualifications, and location. Offers equity in the form of stock options.

We are committed to pay equity and transparency.
