About the role

Structural Engineer role focused on thermofluids within Fluidstack's R&D team, owning structural analysis and pressure-containing designs for high-scale compute cooling systems and associated test infrastructure.

Responsibilities

  • Own the structural analysis of the machine: impeller and rotor stress, casing and pressure containment, and the load paths through the packaged unit.
  • Design the pressure-containing structures, and carry them from first calculation to hardware people are willing to stand next to.
  • Run the rotordynamic and modal work alongside the turbomachinery engineer, covering critical speeds, whirl and the magnetic bearing interface.
  • Design the containment case, so an energetic failure at speed stays inside the machine.
  • Design the test cell structures and fixturing that carry the article, the drive and the loop under load.

Qualifications

  • You’ve taken a pressure-containing design from calculation through to a fabricated article, and it held.
  • You’ve run FEA on rotating hardware and correlated it against strain gauge, spin-pit or test data rather than trusting the model.
  • You’ve owned a containment or burst case and made the argument for why it holds to people whose safety depended on it.
  • You’ve worked the modal and critical-speed problem jointly with whoever designed the aerodynamics, early enough to change both.
  • You’ve signed off a structure that got built, and you were there when it was first loaded.
  • Bonus: Flight and propulsion structures (spin pit testing, burst margin, containment). Rotordynamics and bearing dynamics. High-cycle fatigue and fracture on rotating hardware. Pressure vessel and containment design. Professional Engineer license.
