Fluidstack is building civilization-scale AI compute infrastructure, acquiring power, designing and operating data centers at unprecedented speed and scale. The Modular team designs and manufactures factory-built data center modules that support the largest AI compute buildout in history. In this role, you will engineer the structural systems of modular data center products—frames, enclosures, lifting and transport structures—from concept through released fabrication drawings. You own the structural calculations and load paths, ensuring modules survive fabrication, shipping, rigging, and stacking without redesign. A critical part of the job is solving integration problems where structure meets MEP (mechanical, electrical, plumbing): managing penetrations, attachment points, and tolerances where disciplines collide in tight envelopes. You will run structural support for both factory and field operations, answering RFIs same-day and engineering fixes into the next design revision. You'll drive prototyping and validation through mockups, fit checks, and first-article reviews, attending these in person to ensure designs are production-ready before scaling. The ideal candidate has hands-on experience engineering structures for complex physical products—modular construction, heavy fabrication, modules, trailers, skids, or container conversions. You've taken steel or sheet metal products from concept through fabrication (not just analyzed someone else's design) and supported production launches of your own designs, staying accountable through first articles. You treat transport loads, lifting points, and stacking as first-class design constraints, not afterthoughts. Your drawings are clean: fabricators rarely call, and when they do, you fix the drawing. You work across disciplines, iterate fast without losing configuration control, and have strong DFM (design for manufacturability) instincts. Bonus qualifications include PE license, deep expertise in steel and sheet metal design, knowledge of structural detailing standards (AISC, AWS), mastery of 3D CAD tools (SolidWorks, Inventor, Revit), and proven DFM instincts. Fluidstack operates on extreme ownership, full autonomy, velocity, first-principles thinking, and a deep love of the game. You'll own things end-to-end, often taking on scope outside your core role to get things done.
