  • Experience with attitude determination and/or state estimation algorithms

Preferred skills and experience

  • Master's degree or PhD in physics or an engineering discipline
  • Professional or project experience in state estimation, feedback control, robotics, antenna design and actuation, or similar fields
  • Direct experience with inertial navigation systems, GNSS, and phased array antenna systems
  • Experience with translational state estimation without GNSS ranging and timing information
  • Experience with loosely/tightly coupled state estimation
  • Linux development experience
  • Strong understanding of classical dynamics, modeling and simulation, and software development
  • Ability to identify and solve complex problems independently
  • Active Top Secret, Top Secret SCI, or DOE Level Q clearance, or ability to obtain and maintain one

Working conditions

  • Must be able to work extended hours and weekends as needed to support critical path development and on-orbit operations
  • Active clearance holders will be subject to pre-employment drug and random drug and alcohol testing

Compensation and benefits

Pay Range:

  • Level 1: $125,000 to $160,000
  • Level 2: $145,000 to $195,000
