FluidStack
Structural Engineer, R&D
About this role
Fluidstack is hiring a Structural Engineer for their R&D team to design and analyze pressure-containing structures, rotating machinery, and containment systems for next-generation cooling equipment supporting AI compute infrastructure. You'll own structural analysis from concept through fabrication, ensuring safety at scale for multi-gigawatt thermal management systems.
What you'll do
- Perform structural analysis on impellers, rotors, casings, and pressure-containing components
- Design pressure vessels and containment structures from initial calculations through fabrication sign-off
- Conduct rotordynamic and modal analysis with attention to critical speeds, whirl, and magnetic bearing interfaces
- Design burst containment cases to prevent energetic failures at operational speed
- Design test cell structures and fixturing to support compressor and chiller testing under load
- Correlate FEA models against experimental data from strain gauges and spin-pit testing
What they're looking for
- Finite Element Analysis (FEA) on rotating machinery
- Rotordynamics and critical speed analysis
- Pressure vessel and containment design
- Structural design of turbomachinery components
- Modal analysis and vibration dynamics
- High-cycle fatigue and fracture mechanics
- Technical report writing and safety certification
- CAD and structural modeling software
