Senior Software Engineer - Calibration

Amazon RIVR is a robotics company pioneering Physical AI through real-world doorstep delivery. Founded in 2024 as an ETH Zurich spin-off, RIVR developed wheeled-legged robots designed to operate in complex, unstructured environments such as stairs, gates, doors, and uneven urban terrain. We believe that achieving general physical intelligence requires solving real customer problems in the real world, where robots can learn from rich operational data at scale.

Following our acquisition by Amazon in March 2026, we are continuing this mission with greater reach and speed. By combining custom robot hardware, onboard autonomy, and cloud-based coordination, Amazon RIVR is building the next generation of safe, reliable autonomous robots for last-mile delivery

Job Description

Our robots require precise and real-time perception and localization, which they achieve by utilizing onboard sensors such as IMUs, lidars, cameras, and GNSS. Achieving this precision is critically dependent on highly accurate sensor calibration. As our next Calibration Engineer on a growing team, you will be an expert in designing and implementing robust multi-sensor calibration systems. You will shape our robots’ ability to navigate with pinpoint precision, and you will be part of a team focused on enabling our robots to navigate autonomously. If you are passionate about robotics and driven to develop, maintain, and deploy state of the art calibration algorithms on a robotic fleet, we encourage you to join us in shaping the future of intelligent robotics.
