About the Role:
We are looking for an
Injector Design and Development Engineer to own rocket engine injectors end to end-design, analysis, development, and validation. These injectors power the engines behind our own rockets and satellites, and they need to go from concept to hotfire fast. You will pair first-principles analytical design with hands-on manufacturing and test to drive rapid design/build/test cycles. The ideal candidate blends sharp analytical instincts with a builder's mindset and a relentless focus on turning analysis into flight-ready hardware. This position is onsite in Kent, WA.
Responsibilities:- Own injector hardware end to end, from first-principles sizing through flight operation.
- Perform physics-based architecture trades within a given engine cycle and required performance, leading to design & analysis of Thrust Chamber Assembly piece parts
- Select manufacturing methods and lead the build, iterating on the design across the full lifecycle
- Plan and execute test campaigns, from component tests through full-engine hotfire
- Analyze hotfire data and lead component redesigns to meet mission requirements
- Partner with vehicle and test-stand engineers to keep the engine compatible with operational needs
Basic Qualifications:- Bachelor's degree in Aerospace, Mechanical, Space Systems, or an equivalent Engineering or Applied Physics degree.
- Strong command of first-principles thermodynamics, fluid dynamics, and structural mechanics.

Preferred Qualifications:- Multiple cradle-to-grave cycles owning rocket engine injectors and/or TCA components
- Analysis experience with Ansys Mechanical, Fluent, and/or Thermal Desktop
- Experience using first principles to perform fluid system sizing, injector performance optimization (c*), and mitigation combustion stability concerns
- Design for additive manufacturing, machining, and weld/braze processes
- Experience planning, running, and analyzing rocket engine hotfire tests
- Advanced degree in a relevant engineering discipline
