Propulsion Components Design Engineer (Brushless DC Motors)

Propulsion Components Design Engineer (Brushless DC Motors)

Propulsion - Engine Design and Development

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 is responsible for the valves, actuators, and other fluid control devices on the vehicle. Our components handle fluids from +700 F down to -400 F, high pressures, and extreme flight environments, while maximizing reliability and minimizing weight. Valve design is a multidisciplinary engineering field and our engineers are expected to lead their own projects from concept to flight using their strength in mechanism design.  Finite element analysis, fluid/gas dynamics, heat transfer, vibration dynamics, material selection, system control design, basic electrical engineering and other more specialized fields may also be involved.  Components engineers conduct both computer based engineering tasks and hands-on hardware assembly and testing.


  • Responsible for design and analysis of brushless DC motors for our next gen vehicles
  • Assist in design and development of embedded systems hardware and software for DC brushless motor control
  • Generate and maintain component specifications
  • Generate detailed drawings and coordinate valve manufacturing with the production group
  • Develop and execute component flight qualification test plans (e.g. vibration, shock, thermal cycle, life cycle, burst, etc.)
  • Develop production flight acceptance tests for propulsion components 
  • Document and troubleshoot component anomalies



  • Bachelor's degree in an engineering discipline
  • 2+ years of professional or internship experience in a test focused engineering role
  • 2+ years of experience with brushless DC motor design



  • Working knowledge of valves, regulators, burst disks, and other fluid components
  • Experience working on mechanisms or mechanical systems (e.g. drivetrains, pumps, engines, etc.)
  • Hands-on experience with fluid and/or gas handling systems 
  • Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.) 
  • Proven history of driving projects from concept to completion
  • Programming experience in any of the following languages: LabVIEW, Python, C#, C++, JavaScript, Visual Basic
  • Experience with CAD and FEA software
  • Experience with Microsoft SQL Server and database architecture
  • Excellent written and communication skills
  • Well organized with meticulous attention to detail



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