Product Safety Engineer

RIVR, part of Amazon 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, RIVR, part of Amazon is building the next generation of safe, reliable autonomous robots for last-mile delivery Job Description As our Product Safety Engineer, you will own product-level safety for RIVR's robotic systems as they move from advanced R&D into real-world, urban deployment. This is a highly cross-functional role sitting at the intersection of hardware engineering, software engineering, perception, product and QA teams, with direct impact on how our robots are designed, validated, and approved for operation in public environments. You will lead hazard identification, risk assessment, and safety argumentation across the full robotic system, from sensing and actuation to software behavior and human-robot interaction. While this role does not manage people initially, it has significant technical authority and works closely with senior robotics engineers, systems engineers, legal, and operations to ensure safety is built in by design, not added late for compliance. This role will play a key role in shaping RIVR's product safety practices as our robotics platform and safety organization continue to evolve.
