Senior GNC Engineer - Flight Controls & Autonomy
Hermeus
Los Angeles, CA, USA
USD 150,875-204,125 / year + Equity
Posted on Apr 23, 2026
Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.
As a Senior GNC Engineer at Hermeus, you will help develop and deploy the flight control, navigation, and autonomy systems that enable our aircraft to fly safely and perform reliably in demanding real-world environments. This role will focus heavily on flight controls development, controls modeling, state estimation, and autonomy for advanced aircraft applications, including autonomous takeoff and landing.
You will work across simulation, software, hardware, and flight test to build and validate advanced control and estimation capabilities for high-speed aircraft. This role is ideal for an engineer who enjoys solving hard dynamic systems problems, moving quickly from analysis to implementation, and working closely with cross-functional teams to take algorithms from concept through validation and flight.
Responsibilities:
- Develop and improve flight control, guidance, and navigation algorithms for high-speed aircraft
- Design and implement control laws, estimation logic, and sensor fusion strategies for autonomous and piloted flight applications, with an emphasis on autonomous takeoff and landing
- Develop and analyze linear control models and dynamic system representations to support controller design, stability analysis, and performance assessment
- Build and refine high-fidelity models of vehicle dynamics, sensors, actuators, and control system behavior using MATLAB, Simulink, and related simulation tools
- Conduct 6-DOF simulation, Monte Carlo analysis, regression testing, and performance studies to validate system robustness across nominal and off-nominal conditions
- Support software and system integration across flight controls, navigation, avionics, and other vehicle subsystems
- Execute and analyze software-in-the-loop, hardware-in-the-loop, and system integration testing campaigns
- Support flight test planning, real-time test execution, and post-flight data analysis to validate and improve control and estimation performance
- Collaborate closely with avionics, software, test, and vehicle engineering teams to define requirements, interfaces, and system architecture
- Drive technical trade studies for sensors, estimators, control logic, and autonomy-related subsystems
- Contribute to verification strategies, test coverage definition, and system-level performance validation
- Document technical work clearly through reports, test reviews, and design presentations
Basic Requirements:
- Bachelor’s degree in aerospace engineering, mechanical engineering, electrical engineering, physics, or a related technical field
- 5+ years of professional experience in GNC, flight controls, autonomy, estimation, robotics, or closely related aerospace systems
- Strong fundamentals in dynamics, linear controls, stability analysis, and modeling and simulation
- Experience developing or integrating flight-critical algorithms for aircraft, spacecraft, missiles, UAVs, or other autonomous systems
- Proficiency in MATLAB, Simulink, Python, C++, or similar technical computing and software development tools
Preferred Qualifications
- Experience with flight controls development for autonomous aircraft or other high-performance aerospace systems
- Experience with autonomous takeoff and landing system development, testing, or validation
- Experience with GNSS, INS/IMU, air data systems, and other aircraft navigation sensors
- Practical experience with Kalman filtering techniques, including EKF, UKF, or related estimation methods
- Experience with 6-DOF simulation, control law development, and flight dynamics modeling
- Experience with software-in-the-loop, hardware-in-the-loop, Monte Carlo testing, and regression-based validation
- Experience supporting flight test, post-flight analysis, and control system tuning
- Ability to solve complex technical problems with a high degree of ownership in a fast-paced development environment
- Strong written and verbal communication skills
- Passion for building advanced aircraft and enabling a faster pace of flight development
