Senior GNC Engineer - Flight Controls

Responsibilities

Control Law Design & Tuning
• Design, modify, and tune control laws for assigned flight modes and control loops, such as inner-loop attitude control, outer-loop velocity and position control, and mode transitions, within the established architecture.
• Analyze control laws against stability, performance, and handling qualities criteria, such as stability margins, bandwidth, disturbance rejection, and command tracking, using tools such as CONDUIT.
• Propose improvements to the control law architecture and design criteria based on analysis and test results.
Flight Dynamics & System Identification
• Perform system identification of the aircraft and its subsystems from flight and ground test data, using frequency-domain methods such as CIFER.
• Use identification results to update the flight dynamics models and simulation environment.
Verification & Flight Test
• Develop verification cases for the control laws, including Monte Carlo, worst-case, and failure-case simulations and automated mission-level tests, and analyze the results against requirements.
• Help write flight control requirements and trace them to designs and tests, working with the systems engineering team.
• Help plan flight test points for your area, support flight tests, and analyze flight data to evaluate control law performance and refine the design.
Collaboration & Mentoring
• Review designs and analyses from other engineers, and mentor less experienced engineers.
• Work with the firmware, aeromechanical, and flight test teams on integration issues such as actuator and sensor dynamics, time delays, and flight software implementation.
 

Education

Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or a related technical field.
5+ years of industry experience in flight controls or GNC with a Bachelor’s degree, 3+ years with a Master’s degree, or a PhD with research in flight dynamics or flight controls, or equivalent experience.
 

Experience

• Hands-on experience designing and tuning flight control laws that were evaluated in flight test or piloted simulation.
• Solid understanding of aircraft flight dynamics, including modeling, linearization, and dynamic stability modes.
• Strong foundation in classical and modern control theory, including frequency-domain analysis, state-space methods, and stability margins.
• Experience with multi-loop flight control architectures, such as cascaded loops, explicit model following, or dynamic inversion.
• Experience using simulation to verify control law performance, including Monte Carlo or worst-case analysis.
• Proficiency in MATLAB and Simulink for control design, modeling, and simulation.
• Proficiency in Python or MATLAB for flight data analysis, and in C or C++ for writing application-level code.
• Strong communication skills, and the ability to work independently in a fast-paced, collaborative environment.

Preferred Qualifications

• Master’s degree or PhD in Aerospace Engineering or a related field, with a focus on flight dynamics or flight controls.
• Experience using CONDUIT and CIFER.
• Experience with eVTOL, tiltrotor, rotorcraft, or other VTOL aircraft, including control through the transition between hover and forward flight.
• Experience with handling qualities specifications and evaluations, such as ADS-33, MIL-DTL-32742, and MIL-STD-1797, including piloted simulation evaluations.
• Experience flight testing control laws on full-scale or subscale aircraft.
• Experience with control allocation, envelope protection, or failure accommodation.
• Experience with hardware-in-the-loop and integrated simulation test environments.
• Experience with Git, continuous integration, and agile development workflows, including automated simulation-based regression testing.
• Experience using AI-assisted development tools, such as Claude, to speed up algorithm development, coding, and data analysis.
• Familiarity with DO-178C, DO-331, ARP4754A, and ARP4761.
• Piloting or RC piloting experience, or a strong interest in aviation.
