- Own turbomachinery design (CAD), drawings, and manufacturing plans
- Perform hydrodynamic and aerodynamic sizing and flowpath design and analysis for inducers, impellers, diffusers, nozzles, turbines, and other turbomachinery
- Perform hydrostatic bearing sizing, performance trending, and coatings development for turbopump bearings
- Evaluate axial thrust balance during transients and steady-state operating points
- Perform tolerance stackups, own build books, and ensure as-built pumps meet design intent
- Own test verification activities to ensure tests meet requirements
- Support turbopump testing, data review, inspections, and go/no-go decisions
- Own performance trending of inducers, impellers, turbines, axial and radial bearing capacities, cavitation, and other components
- Own design improvement plans including manufacturing improvements to reduce cost and lead time
- Use and develop high-speed data tools to review turbopump vibration and rotor-dynamics performance
- Resolve hardware build non-conformances through to resolution
- Conduct fault tree investigations and root cause analysis
Qualifications
- Bachelor's degree in mechanical or aerospace engineering, or similar
- 4 or more years of experience in design, build, and testing of rocket engine turbopumps or related turbomachinery
- Demonstrated experience taking extreme ownership of your product
- Demonstrated ability to manage numerous hardware workflows to meet required delivery dates
- Understanding of hydrodynamic and aerodynamic design and fundamentals of turbomachinery
- Extensive experience using CAD tools and configuration management (Siemens NX and Teamcenter preferred)
- Experience with mechanical design including machined parts, additive parts, weldments, fasteners, seals, and rotating assemblies
- Experience in rocket engine turbomachinery axial and radial tolerance stackups and material selection
- Experience in the design, build, and testing of inducers, impellers, volutes, turbines, nozzles, shafts, bearings, and seals
- Experience with secondary flow and axial thrust balance modeling
- Proficiency in heat transfer, compressible and incompressible flow, and cryogenics
- Excellent written and verbal communication
- Willing to relocate to Seattle, Washington
