Apollyon Dynamics is developing autonomous fixed-wing UAVs, VTOL platforms, and defence-grade flight systems. We are looking for a GNC Engineer with a strong hands-on background to own flight control, navigation, and guidance across our vehicle programs.

This is a technical role with real ownership from architecture through to flight test. Experience with autopilot development and a demonstrated contribution to open-source flight stacks is expected.

Responsibilities

• Define and own GNC architecture across vehicle programs, driving requirements into avionics, embedded, and mechanical teams
• Develop 6-DOF flight dynamic models and tune PID, LQR, MPC, and adaptive controllers across the full flight envelope
• Implement guidance algorithms for waypoint navigation, autonomous takeoff and landing, terrain following, and mission autonomy
• Develop and customise autopilot firmware, covering hardware bring-up, integration, and flight...
