Senior Powerpack Engineer

The role

You will own turbopump hardware including design, analysis, fabrication, and testing. You will lead architecture trades and manage the full lifecycle from concept through flight.

What you will do

• Own mechanical design and development of turbopump hardware from concept through flight
• Lead architecture trades on the pump and turbine
• Integrate hydro, aero, structures, rotordynamics, secondary flow, thermal, and bearing constraints
• Perform and direct analysis including FEA, rotordynamic models, and life prediction
• Own the verification argument for hardware
• Select materials and manufacturing processes for cryogenic, high-speed, high-stress service
• Generate detailed component and assembly drawings and design definitions
• Drive hardware through fabrication and build
• Define and execute component and engine test campaigns
• Lead root cause investigations on turbopump anomalies

Required qualifications

• Bachelor's degree in Aerospace, Mechanical, or related engineering field
• Strong grounding in turbomachinery fundamentals: hydrodynamic and aerodynamic performance, rotordynamics, secondary flow, and structural life
• Proficiency in 3D CAD and in producing released, manufacturable design definitions with sound GD&T and tolerance stack-ups
• Experience with structural and thermal analysis, both FEA and hand calculations, validated against test data
• Experience selecting materials and manufacturing processes for high-stress, high-cycle applications
• Hands-on experience taking hardware from design through build and test
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum

Nice to have

• 8+ years of turbomachinery or turbopump experience
• Master's degree or Ph.D. in Aerospace, Mechanical, or related engineering field
• Experience with liquid rocket engine turbopumps or reusable propulsion systems
• Experience taking a turbopump from a clean sheet through first hot fire
• Experience mentoring early career engineers and reviewing their design releases
• Experience with adjacent rotating machinery
• Experience with detailed design and analysis of fluid components, dynamic seals, and rotor support structures
• Experience with rotordynamics, bearing selection, and axial thrust balance on high-speed rotors
• Experience with cryogenic hardware design and cryogenic material behavior
• Experience leading root cause investigations on hardware you owned
