Job Description

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

Job Responsibility

  • Define control system architecture and requirements for fixed-wing vehicles (primary flight control, envelope protection, autothrottle/energy mgmt, and mode logic)
  • Design and implement control laws accounting for actuator limits, time delays, and sensor noise
  • Lead system identification and aerodynamic model development from wind-tunnel, CFD, and flight-test data
  • build accurate linearizations
  • Develop fault-tolerant and reconfiguration strategies (sensor/actuator FDI, control allocation, redundancy mgmt) with graceful degradation
  • Own verification & validation: SIL/HIL campaigns, Monte Carlo, and flight-readiness criteria
  • establish performance dashboards
  • Drive flight-test planning and execution
  • analyze logs, tune controllers, and iterate safely and quickly
  • Mentor the controls team, set technical standards, conduct design/code reviews, and influence roadmap and milestones

Requirements

  • Bachelors in Engineering, Physics, Mathematics
  • 8+ years designing 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
  • Proficiency in modern C++ for embedded real-time implementations
  • strong MATLAB/Python for modeling, ID, and analysis
  • Demonstrated ownership of 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

  • 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)

What we offer

  • Offers Equity
  • healthcare
  • dental and vision plans
  • retirement savings
  • paid time off
  • funds for continuing education, training, and career growth
