About The Role
At ARX Robotics, you will help advance the autonomy stack of next-generation unmanned ground vehicles. As a Staff Engineer – Sensor Fusion & Localization, you will develop core state estimation and sensor fusion systems that enable robots to understand their position and motion in complex, GPS-denied environments.
You will work across autonomy, perception, hardware, and software teams to integrate advanced algorithms into a cohesive and reliable platform for real-world deployment. Your contributions will directly influence how autonomous and teleoperated systems operate in demanding field conditions where precision, robustness, and low latency are critical.
What You’ll Build
- 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 under degraded sensing conditions
- 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
What You Bring
- Advanced degree (MSc or higher) in Robotics, Computer Vision, Electrical Engineering, or a related field
- 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
- Experience with Python, CUDA or edge computing platforms are beneficial
- Familiarity with ML frameworks such as PyTorch, TensorRT, or vision libraries like OpenCV are a plus
