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.
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 DescriptionAs a Senior Electronics Engineer – Functional Safety, you will own the hardware-level Functional Safety design for our robots’ custom electronics.
You will design fault-tolerant circuits at the schematic and PCB level — implementing redundant architectures, hardware diagnostics, and safe-state mechanisms — and perform the quantitative reliability analysis to substantiate that your designs meet the required Safety Integrity Level.
This is a hands-on circuit design role, not a systems-level safety concept or process management position.
What You’ll Be Doing Design fault-tolerant circuits for safety-critical subsystems, selecting appropriate safety architectures (e.
, 1oo2, 1oo2D) based on the required SIL target.
Implement hardware diagnostic and monitoring mechanisms to detect dangerous failures.
Design circuits that enforce a defined safe state when a fault is detected.
Apply Common-Cause Failure mitigation techniques at the component and PCB level.
Build Reliability Block Diagrams and compute SIL metrics to verify your designs mee.
