Senior Electronics Engineer (Motor Control & Power Electronics)

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 As a Senior Electronics Engineer in our Zurich based R&D team, you will be the responsible for the  "muscles" of our robots. Your primary mission is to design, prototype, and validate custom motor controllers and power electronics that redefine what our actuators can achieve. To meet our goal of building more compact and agile robots, you will lead the development of high-power-density PCBAs, allowing us to shrink our motor footprint without sacrificing torque or reliability. You will sit at the unique intersection of physics and firmware, building the high-performance hardware that enables our robots to conquer the last mile. This is a rare opportunity to own the hardware stack of one of the world’s most advanced legged-on-wheels platforms, bridging the gap between theoretical control logic and production-ready intelligence.
