Kent, Washington Apply At Stoke, we believe a thriving space economy will enable a vibrant, sustainable, and equitable future here on Earth. That is why we’re building Nova, our fully and rapidly reusable launch vehicle. Designed for daily flight, Nova tackles the core challenges of space transportation by reducing cost, increasing availability, and improving reliability. By radically lowering launch costs and increasing flight cadence, we’re helping create a truly scalable space industry. Our team is mission-driven, collaborative, and empowered to take ownership of their work. If you want to work alongside some of the most dedicated and talented people on Earth, we’d love to have you join us. Description Fully reusable launch vehicles are the key to seamlessly connecting Earth and space. 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 seek out state-of-the-art design and manufacturing techniques and tools to solve challenging turbomachinery problems, and you will continuously iterate and improve your designs. You’ll also work on rapidly reusable rocket engines meant to be flown daily. You must be ready to stay focused, move fast, self-direct, and learn on the fly. Responsibilities
- Design, build, and testturbopumps for liquid rocket engines
- Own turbomachinery design (CAD), drawings, and manufacturing plans
- Perform hydrodynamic and aerodynamic sizing and flowpath design and analysis work 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's

Stoke is building Nova to turn space transportation into infrastructure. By fully and rapidly reusing both stages, Nova is designed to radically lower cost, compress the time between launches, and give commercial companies reliable access to and from any orbit, at any time, unlocking constellations, in-space manufacturing, dynamic logistics, and the routine return of cargo from space. This is more than an economic opportunity; it is an American strategic imperative. The nation that can launch, maneuver, return, and rapidly reconstitute critical space assets will define the next era of security and prosperity. Nova gives the United States an independent, high-cadence transportation system built to ensure that future is American-led.
