GNC Engineer (Controls)

Support control design and evaluation for Mach’s fixed-wing aircraft. You’ll own your piece of the aircraft design, implementation, and validation of flight-critical control laws—spanning takeoff to landing—delivering robust performance across the full envelope.

Responsibilities

Design control systems within defined architecture and requirements for fixed-wing vehicles; Design and implement control laws accounting for actuator limits, time delays, and sensor noise as part of the controls team; Participate in system identification and aerodynamic model development from wind-tunnel, CFD, and flight-test data; Execute verification & validation work: SIL/HIL campaigns, Monte Carlo, and flight-readiness criteria; communicate findings to the team and program leadership; Participate in flight-test planning and execution; analyze logs, tune controllers, and iterate safely and quickly; Learn from the controls team, carry your work through design/code reviews to meet roadmap goals and milestones

Requirements

Bachelors in Engineering, Physics, Mathematics; 0-5 years designing, analyzing and fielding flight control systems for fixed-wing aircraft or high-performance UAVs, including flight test; Deep knowledge of flight dynamics, stability/controllability, and actuator/sensor modeling; Familiarity with modern C++ for embedded real-time implementations; strong MATLAB/Simulink/Python for modeling, ID, and analysis; Familiarity with verification workflows (SIL/HIL), requirements traceability, and safety reviews; Familiarity with modern software workflows (git, code review, issue tracking) and data/telemetry analysis

Nice to have

Practical and/or academic experience with modern/MIMO control design (LQR, LQG, LTR), system ID techniques, adaptive control; Experience with energy-based control, autothrottle, sideslip/yaw coordination, and advanced control allocation for over-actuated systems; Experience integrating with PX4 and ROS 2; Exposure to DO-178C/DO-331/ARP4754A processes or equivalent rigor; Comfort optimizing for resource-constrained processors and hard real-time constraints (latency/jitter budgets, numerics)

Benefits

health insurance; retirement plans; opportunities for professional development; highly competitive equity grants
