POSITION SUMMARY:
The Mechanical Field Engineer supports data center operations by providing hands-on mechanical expertise across Fluidstack's growing portfolio of AI infrastructure sites. You will be the on-site subject matter expert for mechanical systems, ensuring high availability and reliability of cooling and related infrastructure.
Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
Velocity. We drive everything forward as fast as possible.
First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
Examples of key problems the team is working on
Engineer gigawatts from drawing to energized, in months not years. Capacity Delivery owns technical execution across every build: the drawings, the field questions, and the engineering calls that keep multiple concurrent gigawatt sites moving.
Engineer data centers that go up in months, not years. At that pace rework is not an option: problems get caught on paper or they cost a data hall.
Design it once, build it a hundred times. Every site's lessons roll into the reference design on the way to 10s to 100s of GWs, so each build starts ahead of the last.
Own mechanical engineering for assigned sites: review, field support, and closeout of cooling and piping scope.
Review mechanical packages against the reference design and flag deviations with impact stated, not just difference.
Answer field mechanical RFIs in hours and turn recurring ones into design fixes.
Support startup and commissioning with engineering: flushing, filling, and balancing questions answered fast.
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've done mechanical engineering for data center or industrial plants.
You read P&IDs, hydraulic calculations, and equipment schedules fluently.
You've supported construction and commissioning in the field.
Your RFI answers are fast and right, in that order and both.
Bonus: Liquid cooling systems. PE track. Pipe stress analysis. Modular skid design.
