Outpost is pioneering Earth return logistics for space.

Responsibilities:

  • Design, develop, and test flight and ground software for the return vehicle

  • Understanding of software development best practices: version control, testing, code review
  • Ability to work cross-functionally with avionics, GN&C, and test teams
  • Strong problem-solving skills and comfort working in a fast-paced environment

Preferred Experience

  • Experience with flight software, GN&C, or autonomy systems
  • Experience with real-time operating systems (RTOS)
  • Background at a launch vehicle, satellite, or spacecraft company
  • Experience with CI/CD pipelines and test automation

Compensation:

  • Competitive compensation: $150,000 - $220,000 annual salary; (commensurate with experience).
  • Additional Compensation: Annual performance-based bonuses that reward your impact.
  • Shared upside: Meaningful equity in Outpost so you share directly in the value you help create.
  • Comprehensive healthcare: Medical, dental, and vision coverage to keep you and your loved ones covered. We cover the base tier of medical insurance and all premiums of vision and dental. 
  • Protection when it matters: Company-provided short- and long-term disability coverage for peace of mind, plus life insurance for even more security.
  • PTO: Recharge on your own terms with paid time off, plus 9 days of paid holidays.
  • Invest in your future:401(k) with company match to help you build long-term wealth.
  • Fueled for the mission: Daily DoorDash lunch stipend, plus unlimited snacks, coffee, and tea to keep you energized.
  • Mission that matters: Work shoulder-to-shoulder with leaders from aerospace, new space, and deep-tech industries building the future of orbital infrastructure.
  • Pet Friendly Office: Bring your furry friend into the office so that they can be a part of our mission too.
  • Monthly Company Happy Hours and Events: Drinks at the local bar, hibachi nights, mini golfing and more!
