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
As a Senior Mechanical Engineer, you will lead the design, development, and testing of the physical components and systems of our robots. Your responsibilities will span conceptual design, mechanical engineering, design for manufacturing and assembly, and the integration of electronic systems, ensuring that our robots meet specific application requirements and are cost-effective for large-scale production. We are particularly interested in candidates who have demonstrated experience transitioning projects from prototyping and proof-of-concepts to MVPs, final products, and mass production. If you are passionate about pushing the boundaries of robotic designs, we invite you to join us in shaping the future of intelligent robotics.
Amazon RIVR is committed to building a diverse and inclusive team that values every perspective. If you’re passionate about driving innovation in robotics and creating meaningful impact, we encourage you to apply and bring your unique self to our team.
We believe the best work is done when collaborating and therefore require in-person presence in our office locations.

RIVR is a robotics company pioneering Physical AI for doorstep delivery. We combine neural networks with innovative wheeled-legged robots to automate the most labor-intensive part of delivery, bringing packages and food directly to consumers’ doorsteps, while mastering real-world challenges like climbing stairs, navigating cluttered spaces, and opening gates and doors. With customers already requiring tens of thousands of robots, RIVR is on track to generate more daily data than YouTube within four years, unlocking a powerful data flywheel for General Physical AI.
