Mach Industries is hiring a GNC Engineer (Controls) to support control design and evaluation for our fixed-wing aircraft. You will own your piece of the aircraft design, from implementation to validation of flight-critical control laws spanning takeoff to landing, delivering robust performance across the full envelope.
What You'll Do
- 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 and carry your work through design/code reviews to meet roadmap goals and milestones.
What We're Looking For
- Bachelors in Engineering, Physics, or 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, or 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).
Technical Stack
- C++
- MATLAB
- Simulink
- Python
- PX4
- ROS 2
Benefits & Compensation
- Health insurance
- Retirement plans
- Opportunities for professional development
- Highly competitive equity grants are included in most offers; estimated compensation range is based on a wide range of factors.
