Guidance and Control Software Engineer (Interception Systems) Location: North London - Hybrid Type: Contract - Outside IR35 Rate: Starting at 50 per hour DOE About the Role Our client develops advanced autonomous weapon and interception technologies designed for high-speed target engagement in contested environments. The programme centres on a vision-guided one-way aerial system capable of autonomously detecting, tracking, and intercepting manoeuvring objects. The software architecture combines real-time perception with predictive guidance and control. This role will be central to the development of the onboard flight and guidance stack, implementing estimation, tracking and control algorithms in performance-critical C++ code. The engineer will work closely with perception, simulation and hardware teams to ensure reliable terminal behaviour under real-world conditions. The Guidance and Control Software Engineer position suits an engineer with experience in missile guidance, air defence, seekers, or high-dynamic autonomous vehicles rather than conventional UAV autopilot development. Key Responsibilities Guidance and Control Develop predictive guidance and control algorithms for autonomous interception Implement proportional navigation, pursuit guidance or equivalent terminal control laws Design trajectory prediction and time-to-impact logic for manoeuvring targets Integrate perception outputs into stable closed-loop control behaviour Tune and validate behaviour across ..... full job details .....
