Mechanical Design Engineer (Propulsion Components)

Employment Type

: Full-Time


: Engineering

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 Propulsion Components team develops the most advanced spacecraft and launch vehicle components in the world. Our engineers serve as hardware experts for the flow control devices and mechanisms that drive the critical capabilities on our Dragon and Falcon vehicles - from engine throttling to attitude control. We design and build valves, regulators, and actuators for maximum reliability in extreme environments, with temperatures ranging from +900F to -400F and pressures beyond 10,000 psig.

Component design engineers take full ownership over their hardware: urgently troubleshooting issues at test/launch sites, performing hands-on testing to inform development or root cause investigations, implementing design or test upgrades to improve reliability or reuse, and enabling valve production and certification. Falcon is approaching 10-flight reuse and a highest-ever launch rate in support of our Starlink satellite deployment, and Dragon will return crewed flight capabilities to the United States this year. We are seeking hands-on engineers to tackle open-ended failure investigations, rapidly implement design upgrades, perform flight-like testing to ensure mission success, and deliver components at an industry-leading rate without sacrificing quality or capability.


  • Responsible for troubleshooting, development, and flight readiness of valves, regulators, and actuators on the Falcon 9 and Dragon vehicles
  • Troubleshoot and document component anomalies that arise at the build, test, or launch sites
  • Generate detailed drawings and coordinate valve manufacturing with the production team. Generate and maintain component specifications
  • Develop and execute qualification test plans to ensure readiness for flight (vibration, shock, thermal cycle, life cycle, flow testing)
  • Spearhead root cause investigations and redesigns to improve reliability or production rate
  • Certify hardware for crewed flight and repeated reuse through testing and analysis

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

  • Master's degree in mechanical or aerospace engineering
  • Working knowledge of valves, regulators, burst disks and other fluid control devices
  • Experience working on mechanisms or mechanical systems (e.g. drivetrains, pumps, engines, etc.)
  • Fundamental understanding of launch vehicle and/or spacecraft fluid systems
  • Hands-on experience with fluid and/or gas handling systems
  • Leadership experience on a project or research team
  • Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.)

  • Travel to vendors and other SpaceX sites as needed
  • Must be able to work nights and weekends as needed

  • To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
