As part of a hardworking team of diverse developers, you will create software used by our design, analysis, and test teams. You will work closely with engineering teams to gather requirements and build software that meets or exceeds those requirements. This will require finding innovative solutions to challenging physics problems prevalent in the demanding environments of rocket engines. This role will have a strong focus on tools used for the systems engineering of rocket engines and modeling the performance of engine components. You will share in all Blue Engines product successes by generating tools used by all programs.

Responsibilities include but are not limited to:

  • Developing, upgrading, and reviewing software used by design, analysis, and test teams.

  • Gathering project requirements from engineering teams.
