From the original posting

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.

THERMAL ENGINEER (STARSHIELD)

Starshield leverages SpaceX’s Starlink technology and launch capability to support national security efforts. While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on earth observation, communications, and hosted payloads.

  • Experience with Thermal Desktop and ANSYS Workbench
  • Experience with 3D and reduced-order thermal modeling
  • Ability to identify sizing cases and quickly evaluate the impact of design decisions
  • Excellent oral and written communication skills
  • Ability to deliver against an aggressive schedule
  • Active Top Secret or Top Secret SCI clearance OR willingness to pursue one is preferred. Note that an active clearance may provide the opportunity for you to work on sensitive SpaceX missions. If so, you will be subject to pre-employment drug and random drug and alcohol testing

ADDITIONAL REQUIREMENTS:

  • Must be available to work extended hours and weekends as needed to meet mission critical deadlines
  • Must be able to travel - up to 10-25% work week travel may be required
