Mechanical Engineer, Deployment Engineering

Fluidstack is hiring a Mechanical Engineer specializing in Deployment Engineering for a full-time remote position based in Austin, TX. You'll transform cooling and mechanical systems from design into reliable, production-ready infrastructure at AI-scale data center sites.

What This Role Involves

You own the critical phase where engineering designs meet real construction schedules and field conditions. The deployment engineering team bridges design completion and operations-ready infrastructure—ensuring systems survive equipment integration, energization, and commissioning, then hand off to operations performing reliably under actual AI compute workloads from day one. Your work feeds field learnings back into standardized processes, so solutions proven at one site become repeatable procedures at the next, continuously improving speed and quality across the deployment pipeline.

Day-to-Day Responsibilities

• Execute startup sequences, functional validation, performance verification, and acceptance testing for cooling and mechanical systems across active data center deployments
• Identify and resolve technical conflicts between installation conditions and mechanical system specifications while keeping project schedules intact
• Monitor thermal performance under live AI compute load, detect degradation, and implement corrective measures before availability is affected
• Provide operational support during handoff to the live operations team and respond to thermal incidents or equipment failures on production sites, implementing permanent fixes that prevent recurrence
• Document commissioning procedures, startup checklists, and maintenance run books to standardize and improve consistency across future deployments

What You Bring

• Bachelor's degree in Mechanical Engineering or related engineering field
• Hands-on experience leading or supporting mechanical commissioning at data centers or high-density facilities, with direct accountability through startup and live acceptance testing
• Practical ability to identify installation errors, diagnose performance gaps in chilled water, CDU, or direct liquid cooling systems, and guide corrective action
• Proven track record working effectively with contractors and commissioning agents on active sites while maintaining quality standards
• Willingness to travel to deployment and operations sites up to 50 percent of the time

Bonus qualifications: Professional Engineer (PE) license or active pursuit of licensure; direct liquid cooling or CDU commissioning experience at AI-class rack densities; working knowledge of thermal monitoring systems, computerized maintenance management platforms, and predictive maintenance frameworks; proficiency with CFD tools for operational troubleshooting and thermal validation.

Compensation: $200,000–$250,000 annually, adjusted for experience, technical qualifications, and background. Equity participation through stock options.

About Fluidstack

Fluidstack is architecting and deploying tens to hundreds of gigawatts of AI compute infrastructure by acquiring power generation capacity, designing data centers, and operating them at scale. The company works across integrated hardware and software teams, competing on speed and scale—moving from blueprint to live operations faster than peers. Fluidstack is built on extreme ownership, relentless execution velocity, first-principles thinking, and the conviction that frontier AI infrastructure should expand human freedom and capability rather than constrain it.
