Turning Space into a Transportation Layer for Earth Who We Are:   Inversion builds advanced reentry systems to deliver next-generation capabilities from space.   Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach.   Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds.   Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what's possible in space-based defense and logistics.   What You'll Do:   High-performance maneuvering demands an extremely responsive airframe and control system. As the Senior GNC Engineer (Controls), you will be part of the team that develops high fidelity plant models describing Inversion’s reentry vehicles and you own the development of the flight control system that allows our vehicles to track aggressive guidance commands quickly and crisply.  In this role, you will:   Develop plant models of the vehicle and its subsystems — aerodynamics, actuators, sensors, and structural dynamics — at the fidelity needed for control design and verification   Design and analyze high-rate flight control loops that stabilize a statically unstable airframe across the flight envelope   Deliver the autopilot bandwidth and command tracking needed to respond quickly to real-time guidance commands   Quantify and manage stability margins in the presence of sample rate, latency, actuator dynamics, and structural mode constraints   Integrate and exercise control designs in 3-DOF and 6-DOF flight simulations, including Monte Carlo robustness assessment across dispersed conditions   Carry control algorithms through implementation in real-time flight software and hardware-in-the-loop testing   Work closely with the guidance, aerodynamics, structures, and avionics teams to close vehicle-level performance   Required Qualifications:   Bachelor's degree in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, a related field, or equivalent experience   Typically, 5+ years of applicable experience designing and testing control systems for aerospace vehicles   Experience building plant models of aerospace systems, including aerodynamic, actuator, and sensor dynamics and controlling open-loop unstable systems   Experience with high-rate digital control design, including discretization, sample rate selection, and the management of latency and computational delay   Experience developing and exercising 3-DOF and 6-DOF flight simulations   Strong fundamentals in classical and modern control theory, including frequency-domain loop shaping, stability margin analysis, and state-space methods   Proficiency with MATLAB/Simulink and programming languages such as Python or C++   Demonstrated excellent verbal and written communication skills   Capable of working in a dynamic, fast-paced startup environment   This position is on-site at Inversion HQ in Playa Vista, CA.   Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.   Desired Qualifications:   Master's or PhD in Aerospace Engineering, a related field, or equivalent experience   Experience with autopilot design for reentry, hypersonic, missile, or other high-dynamic-pressure flight systems   Experience applying frequency-domain loop shaping to flight control design, including the construction of phase and gain budgets and the management of two-sided stability margins for conditionally stable systems   Experience modeling actuator nonlinearities, including rate and position limits, and their effect on stability of unstable plants   Experience with flexible-body dynamics and aeroservoelastic effects, including structural mode filtering   Experience with system identification and control-relevant model updates from ground or flight test data   Experience implementing control algorithms in real-time flight software on embedded hardware   Hardware-in-the-Loop (HITL) test experience   Prior experience working in startups and/or small independent teams   The California annual base salary for this role is currently $139,000-$199,000 .  Pay Grades are determined by role, level, location, and alignment with market data.  Individual pay will be determined on a case-by-case basis and may vary based on the following considerations: interviews and an assessment of several factors that are unique to each candidate, job-related skills, relevant education and experience, certifications, abilities of the candidate and internal equity.    #LI-FH1 ITAR Compliance: To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
