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.


The Raptor Components team develops the world's most advanced engine control components! Our engineers are hardware experts for flow control devices that enable the Raptor engine, integrating pneumatics, mechanical, electrical, and software into integrated packages that enable streamlined manufacturing and engine operation. We design, analyze, build, test, and fly components for simplicity, manufacturability, and reliability in extreme thermal, pressure, and vibe environments. You will use and expand your knowledge, experience, and creativity to develop solutions at the cutting edge of space technology. You will own the relationship between your hardware and suppliers, customers, and test teams while spearheading your own projects. You will provide input into vehicle architecture trades and take a lead role in design and flight readiness on Starship, the vehicle that will make humanity multi-planetary.


  • Develop state-of-the-art, manufacturable, 99.9% reliable flow control devices. Question requirements, delete parts and processes, simplify/optimize, accelerate, and automate component deliveries
  • Safely implement thorough component testing and checkouts across multiple build and test sites
  • Spearhead root cause investigations that arise in development, production, test, integration and launch, implementing corrective actions, proactively seeking out hardware issues and implementing solutions early
  • Set the standard for rigorous component design and qualification testing, increasing scrutiny as the vehicle program matures in pursuit of commercial and crewed orbital missions
  • Generate and improve detailed drawings, component specifications, analysis and risk assessments
  • Partner with supply chain, manufacturing, testing, and flight teams to achieve SpaceX’s most reliable, highest rate components, striving for high factory yield and automotive volume/cost
  • Coordinate team of peers through informal leadership and self-directed program organization to achieve goals. Assign clear responsibilities, motivating and holding teammates accountable for execution
  • Be chief engineer, collaborating with peer/engine/vehicle teams to arrive at the simplest solution for the program goals. Inform system-level architecture, with component capabilities and vulnerabilities in mind, to minimize cost of payload to orbit


  • Bachelor’s degree in engineering discipline or physics
  • 1+ years of experience designing and analyzing mechanical systems via professional work experience, project/research-based student experience, or a combination of both


  • Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to optimize modern rocket production and launch processes
  • Strong leadership project management skills and experience, and effective communication of technical concepts across multi-disciplinary teams
  • Master's degree or 1+ years of professional experience in mechanical or aerospace engineering
  • Experience designing, building, testing and troubleshooting mechanical systems
  • Understanding of fundamental principals in fluid systems, solid mechanics, and/or electrical systems
  • Hands-on experience with fluid, gas, mechanical, high voltage, or test instrumentation and control
  • Knowledge of electro-mechanical devices, gears, actuators, motors, valves, regulators, or pumps


  • 10% travel in support of hardware testing and launch operations
  • Willingness to work extended hours and weekends as needed


Pay range:
Propulsion Engineer/Level I: $95,000.00 - $115,000.00/per year
Propulsion Engineer/Level II: $110,000.00 - $130,000.00/per year
