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. Key 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. Required Qualifications • Education: Bachelors in Engineering, Physics, Mathematics • Experience: 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. Preferred Qualifications • 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) ITAR Requirements To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. 1157, or (iv) Asylee under 8 U.S.C. 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
