Own the aerodynamic and mechanical design work for centrifugal compressors in FluidStack’s thermofluids R&D team. Drive concepts from mean-line and 1D modeling through CFD to released impeller, diffuser, and return-channel geometry, then connect design decisions to test-stand performance maps. Also develop turbine expansion stages, rotordynamics, magnetic bearing integration, and guide architecture tradeoffs using incomplete data to deliver built, running machines.

Location: Austin, New York, San Francisco, Los Angeles, Seattle
Workplace: Hybrid
Employment Type: Full time
Job Function: Research & Scientific (R&D)

Key Responsibilities

  • •Own the aerodynamic design of the centrifugal compressor from mean-line/1D through CFD to released impeller, diffuser, and return-channel geometry.
  • •Set machine architecture (stage count, shaft speed, and diameter) while working fluid decisions are still in flux.
  • •Design the expansion turbine to recover shaft work from the high-side pressure drop, sharing shaft work with compressor and motor.
  • •Carry the rotor through rotordynamics, magnetic bearing integration, and structural/mechanical stress at high compact machine speeds.
  • •Test on the test stand and close the loop from measured performance maps back into aerodynamic design.

Pay and Benefits

Salary: USD 210,000 - 260,000 annually

Key Requirements

  • •Designed a radial or axial turbomachine that was built, ran, and you were present for it.
  • •Taken a machine stage from mean-line/1D through CFD and back, understanding when CFD assumptions break.
  • •Worked rotordynamics through resolution on a real shaft with real bearings.
  • •Made early architecture calls (stage count, speed, bearing type) with incomplete data and carried the decisions through build and test.
  • •Read test maps and iteratively changed the design rather than explaining discrepancies away.
