Senior GNC Engineer

Muon Space – Spacecraft Attitude Control System (ACS) Engineer

Muon seeks a talented Spacecraft Attitude Control System (ACS) (Guidance, Navigation, and Control (GNC)) engineer specializing in attitude control design to join our team. The ideal candidate can go both deep and broad across the control system analysis and design process and use a “systems mindset” to collaborate with other disciplines to arrive at an elegant, best‑fit spacecraft design. In this role, you will work with Muon’s Product and Mission Execution teams to develop modular, mission‑agnostic attitude control schemes for our spacecraft platforms that can be extended to meet mission‑specific requirements.

This position is hybrid and requires working on‑site in our Mountain View, CA office three days per week.

• Design and implement attitude control architectures and algorithms in an embedded C++ environment.
• Define requirements for ACS algorithms, hardware, and related systems, including roadmap development that unlock new customer opportunities.
• Perform analysis and simulation of mission‑specific performance.
• Support performance trending and anomaly resolution of on‑orbit systems, including on‑call duties.
• Support software‑ and hardware‑in‑the‑loop test planning, execution, and validation.

• PhD or Master’s degree in mechanical or aerospace engineering or equivalent plus 5+ years of professional experience, or several years of hands‑on experience with GNC analysis and design.
• Software skills in C++.
• Knowledge of control and optimization theory.
• Experience working with common LEO platform attitude actuators and sensors, including reaction wheels, magnetorquers, gyros, star trackers, and magnetometers.
• Expertise in common numerical programming environments (Python, Julia, MATLAB).
• Experience designing, analyzing, and implementing ADCS/GNC subsystems for spacecraft.
• Excellent communication, presentation, and coordination skills.
• Ability to work in a fast‑paced environment with new opportunities each week.
• Experience with control stability analysis of flexible bodies.

• Experience with ADCS of low‑jitter precision pointing platforms, control moment gyros, and vibration isolation.
• Experience with spacecraft flight operations.

The salary range for this role is $138,000 – $208,000 plus a competitive equity grant and comprehensive benefits package. Final compensation will be based on skills, qualifications, experience, and geographic location as assessed during the interview process.
