We're looking for a Senior Guidance, Navigation, and Control (GNC) Engineer to help design the brains that keep our spacecraft precise, agile, and on mission. If you like turning math into flight code and simulations into reality, you'll fit right in.
What You'll Do: Design and implement spacecraft GNC algorithms, owning your work from initial design through simulation validation and flight integration
Develop control and estimation algorithms in modern C++, targeting both simulation environments and embedded flight software
Design feedback control laws with frequency-domain constraints to meet mission pointing and motion performance requirements
Contribute to system-level analysis including sensor and actuator modeling, structural dynamics interaction, and control-structure co-design
Build and validate high-fidelity environment models (orbital dynamics with disturbing forces) and correlate against real-world data
Integrate models and control algorithms into closed-loop simulation frameworks; use them for Monte Carlo analysis and performance characterization
Partner closely with the flight software team to ensure clean integration from simulation to flight
Support hardware-in-the-loop testing and contribute to mission readiness
Your Ideal Skills and Experience: Proficiency in C++, with some exposure to real-time or embedded system development
Solid foundation in control systems design and stability analysis, including frequency-domain methods (Bode plots, phase/gain margin, bandwidth)
Familiarity with guidance algorithms for spacecraft slew planning and constraint handling
Familiarity with state estimation and Kalman filtering
Experience with spacecraft GNC sensors (star trackers, IMUs, sun sensors, GNSS) and attitude actuators (reaction wheels, torque rods, CMGs)
Ability to leverage AI tools to accelerate development and iteration
B.S. or M.S. in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Physics, or related field - or equivalent depth from a Ph.D. program; 3-5 years of relevant experience (or equivalent research depth)
Salary Range: $130,000 - $155,000 per year
