Turbomachinery Engineer Verified today
About the role
As a Turbomachinery Engineer at Stoke, you will have extreme ownership over all aspects of turbomachinery design, analysis, manufacturing, build, testing, and validation for advanced reusable rocket engines. You will work on the Nova launch vehicle, designed for daily flight to reduce launch costs and increase flight cadence. You will seek out state-of-the-art design and manufacturing techniques, continuously iterate and improve your designs, and stay focused to move fast and learn on the fly.
Responsibilities
- Design, build, and test turbopumps for liquid rocket engines
- 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 accomplished tests meet requirements
- Support turbopump testing, data review, inspections, and go/no-go decisions
- Own performance trending of various components (inducers, impellers, turbines, axial and radial bearing capacities, cavitation)
- Own design improvement plans for turbopump components 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 resolution
- Conduct fault tree investigations and root cause analysis
Requirements
- Bachelor's degree in mechanical or aerospace engineering, or similar
- 4+ years of experience in design, build, and testing of rocket engine turbopumps or related turbomachinery
- 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
- Demonstrated ability to manage numerous hardware workflows to meet required delivery dates
- Demonstrated experience taking extreme ownership of your product
- Willing to relocate to Seattle, WA
