Reflect Orbital
Principal GNC Engineer
$130K–$220K
Hawthorne, CA · On-site · Principal · Full-time · Posted Sep 2, 2026
- Experience
- 10+ years of professional GNC engineering experience; ideally on spacecraft or other dynamically controlled vehicles.
About the job
Own full-stack guidance, navigation, and control development for a space vehicle that directs reflected sunlight to the ground, from dynamics and simulation through flight software and testing.
What you'll do
- Design, develop, and test closed-loop attitude and orbit GNC; plan trajectories and attitude profiles.
- Develop and own 6-DOF vehicle simulation, assess performance through Monte Carlo analysis, and validate flight software with avionics-in-the-loop testing.
- Support sensor and actuator selection, orbit and constellation planning, and spacecraft operations.
What they ask for
- 10+ years of professional GNC engineering experience; ideally on spacecraft or other dynamically controlled vehicles.
- Technical ownership of a flown GNC subsystem spanning simulation, algorithms, and flight software.
- Expertise in physical-system modeling, attitude and orbit state estimation, and integrated flight-software verification and validation using HITL.
- Fluency in Python, C++ and/or Rust.
Nice to have
- Experience in guidance, maneuver, and constellation design, including orbit selection, coverage, and station-keeping.
- Experience supporting real-time spacecraft operations, from commissioning and console operations to on-orbit anomaly resolution.
