Embedded Systems Engineer (Senior)

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
 
The Senior Embedded Systems Engineer is the technical backbone of our robots—the person who turns physics into performance and silicon into intelligence. You will own the firmware that directly controls motion, perception, power, safety, and communication across both our rapidly evolving in-house prototypes and our production-bound robotic platforms. This is not a “desk-only” role: your code will run outdoors, in rain, dust, cold, vibration, failure, recovery, and scale.
 
At RIVR, we build embedded systems the only way that works in reality: hardware first, theory second. No simulation, test bench, or spec sheet replaces being next to a robot in the field while it fails, recovers, and pushes its limits. That’s why our embedded engineers move fluidly between early experimentation and real-world deployment—bringing up new boards, hacking fast on prototypes, and hardening systems for long-term reliability.
 
Our embedded development philosophy balances speed and rigor. We move fast on prototypes to unlock new capabilities, validate assumptions, and de-risk bold design choices, but we apply production-grade thinking from day one. Architecture before implementation, tight hardware–software co-design...
