SpaceX is developing the Starship spacecraft and Super Heavy rocket, a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. The company needs software engineers to design, develop, and test software that is used to both control and simulate these flight systems to achieve the mission.

Requirements

  • Proven skills and knowledge of C++, Rust, or other systems programming language
  • Experience building or working with real-time embedded systems or distributed computing systems
  • Strong focus and interest in designing, architecting, and implementing excellent, bug-free software
  • Basic knowledge of electronics, controls, fluid systems, motor design, or physical mechanics
  • Strong critical thinking and first-principles problem-solving skills

Responsibilities

  • Design, develop, and test software that is used to both control and simulate SpaceX flight systems.
  • Engage with other SpaceX software and hardware engineers to implement and debug software at all layers of our stack – application, operating system, networking, firmware, simulation – to achieve the mission.
  • Develop highly reliable autonomous software systems and the simulations required to validate them
  • Own all aspects of software development, including design, testing, and integration to the mission
  • Work with counterpart engineering teams to develop and maintain launch and vehicle software, crossing all required software domains necessary to implement and verify control of the pad, ship, and booster to meet mission objectives
  • Follow and maintain high software standards and software engineering best practices within Starship Software

Other

  • Aerospace experience is not required to be successful here - rather we look for smart, motivated, collaborative engineers who love solving problems and want to make an impact on a super inspiring mission.
  • Excellent written and verbal communication skills
  • Able to work effectively in a dynamic environment while assuming high levels of responsibility and demonstrating accountability for software outcomes
  • Willing to work long hours and weekends as needed
  • To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
