Job description
A fast-growing satellite company is looking for a Senior Guidance, Navigation & Control (GNC) Engineer to join a small spacecraft team building the next generation of LEO communications satellites.
This is a highly hands‑on role where you will design, implement, and deploy real spacecraft GNC algorithms, working closely with flight software, hardware, and mission operations teams as satellites move from concept through launch and on‑orbit operations.
The team is developing and launching a new satellite platform, with multiple spacecraft launches planned over the next four years, starting with the first launch later this year.
If you enjoy solving difficult spacecraft problems, writing real flight algorithms, and working in a small, fast‑moving engineering team, this role offers the opportunity to directly shape the next generation of satellite systems.
What You'll Work On
Designing and implementing spacecraft guidance, navigation, and control algorithms
Developing orbit determination and maneuver planning solutions for LEO satellites
Writing flight‑ready software for GNC systems in Python, C, or C++
Performing trade studies, modeling, simulation, and Monte Carlo analysis
Supporting integration, testing, and hardware validation of spacecraft subsystems
Working closely with flight software, avionics, and hardware teams
Troubleshooting real spacecraft behavior during integration, test, and on‑orbit operations
Improving fault detection, mitigation, and robustness of spacecraft control systems
Core Experience
What They're Looking For
MS or PhD in Aerospace Engineering or related field
6+ years of experience in spacecraft GNC or ADCS systems
Experience with satellite attitude estimation, navigation, and control
Experience designing orbit determination and maneuver planning algorithms
Strong programming ability in Python, C, or C++
Experience working on real spacecraft missions from concept through operations
Familiarity with LEO satellite missions
Technical Strengths
Nonlinear estimation methods (e.g., Kalman Filters / EKF / UKF)
Spacecraft trajectory and orbital analysis
Simulation and modeling tools such as Basilisk, GMAT, STK, or FreeFlyer
Understanding of spacecraft pointing modes, maneuver planning, and mission operations
Experience supporting integration, test, and on‑orbit anomaly resolution
Nice to Have
Focus on navigation / orbit determination
CubeSat or SmallSat mission experience
Experience with low‑thrust maneuver planning
Communications satellite experience
Hands‑on work with spacecraft hardware or test environments
What Makes This Role Different
Work on a small, tightly integrated spacecraft team
Engineers own both algorithms and software implementation
Direct interaction with hardware, flight software, and mission operations
Opportunity to improve real spacecraft systems that are flying soon
Startup‑style environment where engineers can move quickly and make technical decisions
