Kent, US · Full-time · $95,550 – $327,810

About this role

At Stoke, we’re building Nova, our fully and rapidly reusable launch vehicle designed for daily flight. It tackles core challenges of space transportation by reducing cost, increasing availability, and improving reliability. As a Turbomachinery Engineer, you will have extreme ownership over all aspects of turbomachinery design, analysis, manufacturing, build, testing, and validation for advanced reusable rocket engines.

You will design, build, and test turbopumps for liquid rocket engines while owning turbomachinery design using CAD, drawings, and manufacturing plans. Perform hydrodynamic and aerodynamic sizing, flowpath design, and analysis for inducers, impellers, diffusers, nozzles, and turbines. Evaluate axial thrust balance during transients and steady-state operating points, and handle tolerance stackups and build books.

Our team is mission-driven, collaborative, and empowered to take ownership of their work. You will work alongside some of the most dedicated and talented people on Earth. Be ready to stay focused, move fast, self-direct, and learn on the fly for rapidly reusable rocket engines meant to be flown daily.

Seek out state-of-the-art design and manufacturing techniques and tools to solve challenging turbomachinery problems. Continuously iterate and improve your designs while owning performance trending, test verification, and design improvement plans. Resolve hardware non-conformances and conduct root cause analysis to ensure pumps meet design intent.

Requirements

Demonstrated experience as an RE who takes extreme ownership of their product
Demonstrated ability to manage numerous hardware workflows to meet required delivery dates
Bachelor’s degree in mechanical or aerospace engineering, or similar
2+ years of experience in design, build, and testing of rocket engine turbopumps or related turbomachinery
Understanding of hydrodynamic/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/radial tolerance stackups, material selection, and secondary flow and axial thrust balance modeling

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 and support turbopump testing, data review, inspections, and go/no-go decisions
Own performance trending and design improvement plans for turbopump components including manufacturing improvements
