Requirements

  • Either a Bachelor's degree in a STEM field with at least 2 years of aerospace or space GNC experience, or a Master's degree in a STEM field focusing on dynamics and control.
  • Experience (including internships, full-time roles, or projects) designing and implementing algorithms for sensor fusion, state estimation, trajectory guidance, and control.
  • Strong understanding of dynamics, linear algebra, and 3D rotation math (rotation matrices, quaternions, eigen-decomposition), as well as spacecraft attitude and orbital dynamics.
  • Ability to solve complex, novel problems with little to no supervision, both independently and as part of an integrated team.
  • Ability to work onsite in Seal Beach, CA.

Preferred Experience

  • Experience operating and/or developing spacecraft.
  • Experience with optical navigation.
  • Experience with relative dynamics, rendezvous, and proximity operations.
  • Experience with IMUs, star trackers, sun sensors, reaction wheels, and other GNC hardware.
  • Experience implementing GNC algorithms into robust and reliable flight software.
  • Demonstrated experience in a software engineering environment using best practices such as version control, continuous integration, and unit testing.
  • Experience working in a startup environment.
