Responsibilities

Develop onboard motion planning with obstacle avoidance, replanning, and perception-aware planning.
Generate dynamically feasible trajectories and references within airframe and actuator limits.
Design guidance laws that steer the aircraft along references and maintain the desired path.
Define interfaces with navigation and perception systems, including handling latency, rate changes, and input dropouts.
Develop mode and failsafe logic for cruise, loiter, approach, and lost-link behavior.
Validate systems through simulation, SITL, HITL, Monte Carlo campaigns, and flight testing, then diagnose and iterate using logs.
Mentor junior engineers depending on seniority.

Degree in aerospace, robotics, GNC, or a related STEM field, with strong academic performance, or an equivalent practical track record.
Proven experience with onboard motion planning, trajectory generation, trajectory tracking, and guidance laws on flying platforms.
Hands-on experience closing a control loop on perception outputs while handling latency and dropout.
Familiarity with learning-based planning or guidance and simulation-based training, with judgment to compare these methods against classical approaches.
Systems-minded, pragmatic about failure modes and imperfect inputs, and disciplined about simulation and validation.
Clear communication skills, including presenting guidance and test results to engineers and senior stakeholders.
Experience with vision-based or perception-coupled guidance is a bonus.
Commitment to Harmattan AI’s mission of providing a defensive edge to allied nations through ethical, high-impact technology.
