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.

Even if you don’t tick every box, we encourage you to apply - we’d love to hear from you.
