Software Engineer, Flight Dynamics

Muon seeks a Flight Dynamics Software Engineer to join our Mission Planning Platform team. This role focuses on orbit determination and flight dynamics software development for Muon's constellation of LEO Earth‑observation satellites. You will work closely with our flight dynamics lead to build, maintain, and operate the ground systems that ensure we know exactly where our satellites are, where they need to be, and plan where they all need to go - with direct impact on mission success.

• Operate and evolve Muon's orbit determination (OD) pipeline, fusing tracking data with dynamical models to estimate and predict spacecraft state
• Investigate and resolve OD anomalies as part of continuous operational support
• Support orbit propagation and prediction for mission planning and collision avoidance
• Develop and maintain automation for routine flight dynamics workflows, building toward autonomous constellation operations
• Contribute to the development of Muon's flight dynamics software (MuFDS)
• Collaborate with systems and operations teams to support maneuver planning and execution as needed

• B.S. or higher in aerospace engineering, astrodynamics, physics, applied math, or related field
• 2+ years of experience in orbit determination or general flight dynamics
• Software development experience in C++ and Python
• Understanding of orbit determination theory and methods (batch least squares, statistical filtering approaches, etc.)
• Familiarity with modern software engineering practices (version control, code review, automated testing)
• Ability to translate first‑principles analysis into production‑level code
• Comfortable working in a fast‑paced environment with evolving priorities

• Experience with spacecraft operations or mission operations environments
• Familiarity with astrodynamics data formats (TLEs, OEMs, ephemeris formats)
• Experience with propulsion planning or maneuver design for LEO satellites
• Experience with scheduling or constrained optimization problems (e.g., pass scheduling, contact planning)
• Experience with cloud‑based services or ground software systems
• Comfortable working in Linux‑based development environments

At Muon salary is only part of our total compensation package.
