Role summary

Harmattan AI, a defense technology company focused on autonomous systems, is seeking a GNC Engineer for its UAV team. This role involves designing, developing, and implementing advanced guidance, navigation, and control solutions, from sensor fusion and control law development to simulation and embedded implementation. Responsibilities include algorithm development, simulation testing, flight data analysis, and system integration. The ideal candidate will have a strong foundation in control theory, estimation, sensor integration, proficiency in Python and C/C++, and experience with simulation tools and version control. A degree in engineering or computer science and 3+ years of experience in aerospace GNC systems are required.

About Us

Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.

Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.

About the Role

As a GNC Engineer on the UAV team, you’ll design and develop advanced guidance, navigation, and control (GNC) solutions. From integrating and fusing sensor data to developing control laws and flight trajectories, you'll take your work from simulation to embedded implementation—and ultimately to live flight testing.

Responsibilities

Develop state-of-the-art navigation and sensor fusion algorithms for UAVs
Design and implement GNC and flight control systems
Build filtering and estimation strategies for robust and efficient flight performance
Run extensive simulations (Monte Carlo, SITL, HITL) and coverage testing
Analyze test flight data and refine algorithmic performance
Support full-stack system integration: GNSS, INS/IMU, localisation, and fusion
Maintain and evolve a flight-proven flight computer across multiple UAV platforms

Requirements

Education: Engineering school or master's degree in computer science, engineering, or a related technical field
3+ years of experience in aerospace GNC systems
Strong foundations in control theory, estimation, and sensor integration
Proficient in Python and embedded C/C++
Experience with simulation tools (e.g., Gazebo) and version control (Git)
Familiarity with open-source autopilots (PX4, Ardupilot, Betaflight, etc.)
Hands-on electronics and integration skills: debugging, soldering, harnessing
Commitment: 100% dedication to Harmattan AI’s mission, vision, and ambitious growth plans, ready to go the extra mile to ensure operational excellence.
Bonus: FPV pilot hobbyist

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
