SpaceX
Propulsion Engineer (Starship)
About this role
SpaceX seeks a Propulsion Engineer to design and develop fluid systems for Starship and Super Heavy vehicles, including high-pressure gas storage, cryogenic management, and thermal control. The role spans concept design through manufacturing, structural analysis, testing, and flight operations at the Starbase facility in Texas.
What you'll do
- Perform fluids system sizing analysis and determine basic system requirements
- Transform requirements into hardware concepts and trade implementation options
- Design pressurized and unpressurized structures using CAD and create engineering prints
- Perform structural analysis to ensure component survivability under flight conditions
- Execute design-for-manufacturability improvements and drive first-build production
- Coordinate development, qualification, and acceptance testing of flight hardware
What they're looking for
- Mechanical and fluids design or analysis
- CAD modeling (Siemens NX or equivalent)
- Finite Element Analysis (FEA)
- GD&T (Geometric Dimensioning and Tolerancing)
- Pressurized component design (valves, regulators, tubes)
- Fluid dynamics and thermal management
- Structural calculations for operation-critical components
- Manufacturing design and process optimization
