About The Company
At AstroForge, our mission is to make space resources accessible on Earth. We mine asteroids to extract valuable minerals in space at a lower cost and smaller carbon footprint than current terrestrial mining methods. Along the way, we seek to leverage the technologies we build to provide additional value across other domains. We offer a unique opportunity to join an exciting team looking to expand humanity's capabilities in space.

Job Description
As a GNC engineer at AstroForge, you'll own a large part of the flight algorithms powering the world's first asteroid mining vehicles. You'll be part of a talented team of engineers to develop, analyze, and test vehicle algorithms and software for reliable, fault-tolerant flight. You should love to solve hard, multidisciplinary problems, be able to learn quickly, and thrive in a fast-paced, dynamic environment.

Responsibilities

  • Design, implement, and test innovative guidance, navigation, control, and perception algorithms in flight software for highly autonomous deep space missions.
  • Develop 6-DOF dynamics simulation models used for GNC systems analysis and validation.
  • Help push flight software to the edge in Monte Carlo and Hardware-in-the-loop testing and contribute fixes and performance improvements.
  • Review algorithms and software contributed by GNC / flight software engineers.

Requirements

  • Either:

  • A Bachelor's Degree in a STEM field with at least 2 years aero or space GNC experience

  • A Master's Degree in a STEM field focusing on dynamics & control

  • Experience (incl. internships, full time roles, or projects) designing and implementing algorithms for sensor fusion, state estimation, trajectory guidance, and control.

  • Well versed in dynamics, linear algebra, and 3D rotation math (rotation matrices, quaternions, eigen-decomposition) as well as spacecraft attitude & orbital dynamics.

  • Capable of solving complex, novel problems with little to no supervision on schedule as an individual or as a member 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 software engineering best practices: version control, continuous integration, unit testing.
  • Experience in a startup environment.

Benefits

  • 100% paid medical, dental, and life insurance coverage
  • Vision and FSA benefits available
  • 3 weeks of PTO + 1 week of sick time
  • 10 paid holidays
  • Retirement savings plan - 401(k), with company match
