Role:

• Design, implement, and test closed-loop control algorithms for precise pointing, station-keeping, detumble, and desaturation maneuvers for satellites in orbit
• Develop and maintain high-fidelity satellite simulations to validate GNC control algorithms prior to flight
• Validate and verify algorithm performance through software simulation, Monte Carlo analysis, hardware in the loop, and on-orbit testing
• Perform stability analysis in both time and frequency domains, including gain tuning, margin assessment, and notch filter design for structural flex modes
• Support system identification efforts using in-orbit telemetry to refine onboard models and improve controller performance
• Ability to effectively collaborate with interdisciplinary teams on large projects
• Develop operational procedures and provide mission planning support
• Support GNC operations for our fleet of satellites, including on-console and on-call rotations
• Support in recruiting, interviewing, and hiring additional teammates to our rapidly growing team

Requirements:

• B.S. or higher in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or a related technical discipline
• 5+ years of industry experience in GNC, controls, or a closely adjacent discipline
• Strong fundamentals in classical and modern control theory, including frequency-domain analysis (Bode plots, Nyquist, gain/phase margins)
• Experience designing and implementing closed-loop control systems for dynamic systems
• Experience with gain optimization, linearization, and controls tooling development
• Demonstrated experience modeling flexible body dynamics and mitigating their effects through system design and control systems
• Proficiency in Python for algorithm development and simulation
• Experience with modern C++ for on-board software
• Strong problem-solving skills and attention to detail
• Strong written and verbal communication skills and ability to work in a fast-paced, iterative environment
• US Citizenship or Green Card

Bonus:

• Direct experience with spacecraft attitude control systems (reaction wheels, thrusters, gimbals)
• Understanding of orbital mechanics and geostationary stationkeeping strategies
• Familiarity with electric or chemical propulsion-based control (e.g., stationkeeping, momentum management maneuvers)
• Background in estimation theory or Kalman filtering for attitude/orbit determination
• Hands-on experience with hardware-in-the-loop testing or real-time simulation environments
• Experience supporting live satellite operations or anomaly resolution
• Experience with AI tooling and agentic workflows
