Propulsion Fluids Analyst (Raptor Chamber And Nozzle)
About The Position
SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. PROPULSION FLUIDS ANALYST, RAPTOR CHAMBER AND NOZZLE The Raptor Chamber and Nozzle team designs, analyzes, builds, and tests the Thrust Chamber Assembly (TCA) of the Raptor rocket engine for both the Sea Level and Vacuum variants of the engine, including the Nozzle Extension. The TCA interfaces with many other engine components, both upstream and downstream, while operating under extreme pressure and temperature conditions. Propulsion Fluid Analysts have the opportunity to develop innovative improvements to the TCA fluid circuit and take these designs from initial concept to flight.
Requirements
