Senior Robotics Engineer - State Estimation, VIO & Sensor Fusion

About Promethion Industries Promethion Industries is a European defence technology company building autonomous supremacy systems for aerial and multi-domain operations. Our mission is to enable decisive autonomy for NATO-aligned forces through tightly integrated autonomy stacks designed and built in Europe. Our focus is defensive and counter-system capabilities, including anti-UAS and resilient autonomy under contested conditions. We are looking for a Senior Robotics Engineer - State Estimation, VIO & Sensor Fusion to build the estimation backbone that allows our aircraft to understand their own motion without depending on GNSS. Your mission with us • Build the state-estimation and sensor-fusion backbone of our autonomous aerial systems. • Develop robust vehicle-state estimation for high-dynamic flight and GNSS-degraded or GNSS-denied environments. • Fuse IMUs, cameras, optical flow, airspeed, GNSS, barometers and other sensors into reliable low-latency estimates. • Develop, integrate and deploy VIO, visual odometry, ego-motion optical flow and inertial-estimation approaches. • Own temporal calibration, sensor synchronisation, coordinate frames and estimator consistency. • Diagnose drift, bias, observability and timing problems from first principles. • Work directly with real flight logs and hardware to reproduce estimator failures and rapidly improve performance. • Build graceful degradation when individual sensors become unreliable or unavailable. • Quantify estimator uncertainty and expose meaningful confidence and health information to downstream autonomy and control systems. • Evaluate alternative estimation architectures including direct velocity estimation and continuous-time approaches where they provide advantages at high dynamics. Your contribution to the team (required) • Strong practical experience in robotics state estimation, localization or inertial estimation. • Deep understanding of IMU-based estimation and multi-sensor fusion. • Strong experience with EKF, error-state filtering or comparable nonlinear-estimation techniques. • Practical experience with VIO, visual odometry, optical flow or closely related systems. • Strong understanding of rigid-body transformations and coordinate frames. • Strong C++ skills. • Experience deploying estimators onto real robots or vehicles. • Strong understanding of sensor calibration and time synchronization. • Experience analyzing raw sensor data, logs and estimator performance. • Ability to work with high-rate, noisy and imperfect real-world measurements. Big plus • High-speed UAV or fixed-wing experience. • GNSS-denied flight. • PX4 estimator experience. • ROS2. • GTSAM / Ceres / Eigen. • Event-camera VIO or optical flow. • Continuous-time estimation. • Radar-aided or RF-aided estimation. • Air-data integration. • Aviation, defence, autonomous vehicles or space systems.
