Staff Engineer, Sensor Fusion & Localization (m/f/d)

The role

You will develop core state estimation and sensor fusion systems for next-generation unmanned ground vehicles. You will work across autonomy, perception, hardware, and software teams to integrate algorithms for robots in GPS-denied environments.

What you will do

• Develop advanced sensor fusion and state estimation algorithms for robust localization in GPS-denied environments
• Implement and improve methods such as EKF, UKF, particle filters, and nonlinear observers for state estimation and factor graph-based SLAM methods
• Fuse and synchronize data from cameras, LiDAR, radar, IMUs, GNSS, magnetometers, and barometers into reliable real-time state estimates
• Design low-latency, real-time processing pipelines for autonomous robotic systems
• Build and refine localization performance through simulation, controlled testing, and real-world validation
• Collaborate closely with hardware and software teams to ensure accurate calibration, synchronization, and system integration
• Prototype, evaluate, and deploy new multi-sensor fusion and estimation approaches
• Debug and resolve complex issues across sensor data, calibration, and estimation pipelines
• Contribute to resilient GPS-denied navigation capabilities for autonomous ground vehicles

Required qualifications

• Advanced degree (MSc or higher) in Robotics, Computer Vision, Electrical Engineering, or a related field
• 8+ years of professional experience developing real-time sensor fusion and localization pipelines or state-estimation architecture for autonomous systems in regulated sectors
• Strong C++ development skills with experience debugging complex robotics systems
• Deep expertise in sensor fusion and state estimation methods, including EKF, UKF, particle filters, and nonlinear estimation techniques
• Solid understanding of inertial navigation and visual-inertial concepts
• Hands-on experience integrating and calibrating multi-sensor systems (LiDAR, camera, IMU, GNSS, radar)
• Strong foundation in linear algebra, probability theory, and 3D geometry
• Experience working with ROS2 and simulation environments for algorithm development and validation
• Familiarity with Linux-based development workflows, CI/CD pipelines, and modern robotics software practices
• A structured, self-driven approach with strong problem-solving and debugging skills in complex systems

Nice to have

• Experience with Python, CUDA or edge computing platforms
• Familiarity with ML frameworks such as PyTorch, TensorRT, or vision libraries like OpenCV

Benefits

• Competitive compensation package including a bonus opportunity
• 27 vacation days to start, increasing with tenure up to 30 days
• Employer-supported pension contribution
• Learning & development support and team events budget
• Employee discounts and flexible benefits budget via Probonio
• Hybrid working setup depending on role and team needs
• Structured salary bands, levelling framework, and bi-annual development conversations
