Guidance, Navigation & Control (GNC) Engineer - Interceptor C-UAS (m/f/d)

About us You will be responsible for developing and deploying key driving functions within our interceptor platform, focusing on Guidance, Navigation & Target Tracking, or Control. From algorithm development and system integration to flight testing and field debugging, you will help deliver reliable autonomous capabilities in demanding operational environments.

What is your Day to Day Mission: Depending on your background and expertise, your primary focus will be in Guidance, Navigation, or Control. You will take ownership of one of these areas while working closely with engineers across the broader GNC stack to deliver a reliable autonomous interceptor system. Guidance: Develop and deploy guidance algorithms that convert mission objectives and estimated vehicle and target states/predictions into feasible control commands. predictive approaches that account for target motion and maneuvers.

Navigation & Target Tracking: Develop and integrate state-estimation, sensor fusion, and target-approaches that provide reliable states short-horizon predictions, including sensor fusion and uncertainty modeling.

Control: Develop and doe flight-control algorithms that translate guidance commands into stable, responsive, and feasible behavior across the operating envelope.

Across all three focus areas, you will: Integration: Integrate algorithms with perception, flight-control, simulation, and operator systems through ROS 2, MAVLink, and related interfaces.

Benchmarking and Validation: Validate performance through simulation, recorded-data replay, SITL/HITL, and flight testing.

Field Debugging: Analyze real logs, reproduce failures, isolate root causes, and improve the system until it works not only on your machine, but in the field.

What You Bring to the Team You're structured, fast-moving, and a team player. You iterate fast and work with a high degree of automation. You love building things that last and analyze and fix root cause over applying short-term patches.

Degree in robotics, aerospace, engineering, mechanical engineering, applied mathematics, computer vision, or a comparable technical field.

Several years of hands-on experience in the field. We therefore consider relevant experience gained through student clubs, internships, or working student positions.

Strong fundamentals in guidance, control, vehicle kinematics and dynamics, state estimation, optimization, and dynamical systems, with deep expertise in least one of these areas.

Strong implementation skills in C++ or Rust and experience with ROS 2.

Good understanding of coordinate frames, quaternions, NED/ENU conventions, timing, and filtering.

Experience with interception or predictive guidance, PID or model-based control, trajectory optimization, or model-predictive approaches.

Experience with PX4, ArduPilot, MAVLink, or similar flight-control ecosystems.

Experience with system identification, flight dynamics modeling, target tracking, or GNSS-denied navigation.

Experience with simulation, SITL/HITL, flight-log analysis, structured flight testing, or multi-vehicle driving.
