AI Summary

A hands-on Test Engineer designs and builds mechanical test rigs and automates test procedures to verify the reliability and performance of robotic systems, collaborating with mechanical and electronics engineers.

About this role

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

We are looking for a hands-on and curious Test Engineer to ensure the reliability and performance of our advanced robotic systems. This is a unique, mixed-profile role at the heart of our hardware development. You will be responsible for the entire testing lifecycle: from designing and building physical test setups for mechanical components to writing scripts that automate stress and performance tests. If you love tinkering with hardware, have a knack for mechanical assembly, and enjoy using code to solve real-world problems, this role offers a fantastic opportunity to make a direct impact on the quality of our robots.

What you’ll be doing

Design and build custom test rigs, jigs, and fixtures for mechanical and mechatronic components (e.g., for functional testing, thermal performance characterization, durability and reliability testing).

Execute a wide range of hands-on tests, spanning from structural to safety behavior..

Develop and maintain scripts (e.g., in Python) to automate test procedures, control test hardware (like actuators and sensors), and log critical data.

Analyze test data to identify failure modes, performance bottlenecks, and areas for design improvement.

Collaborate closely with mechanical and electronics engineers to understand component specifications and provide crucial feedback based on your test results.

Meticulously document your test procedures, setups, and findings to ensure repeatability and knowledge sharing.

What you must have

A Master’s degree in Mechanical Engineering, Electronics, Robotics, or a related technical field.

Proven hands-on experience building and assembling mechanical or electro-mechanical systems.

An in-depth understanding of testing procedures for product development.

Scripting proficiency in a language like Python, used for automation, device control, or data analysis.

The ability to work independently in a workshop environment and use common hand tools and power tools safely.

Strong problem-solving skills and a detail-oriented mindset.

Get some bonus points

Hand-on experience with ROS/ROS2.

Experience with CAD software (like SolidWorks, Fusion 360, or similar) for designing test fixtures.

Familiarity with data acquisition (DAQ) hardware and sensors (e.g., load cells, encoders, thermocouples).

Basic knowledge of electronics for wiring test setups.

Experience in a testing environment within the robotics, automotive, or aerospace industries.
