About the role

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.

Harmattan AI's standard text

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, localization, 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
  • Bonus: FPV pilot hobbyist
