Testing Engineer

Rivr; Zürich; On-site; CHF 110,000 - 140,000; Full time

Job summary

RIVR, part of Amazon, seeks a hands-on Test Engineer to ensure reliability of robotic systems. This role spans hardware testing, fixture design, and test automation in a fast-paced hardware development environment.

You will build custom test rigs, run diverse tests, write Python scripts to automate procedures, and collaborate with mechanical and electronics engineers to improve product quality.

Qualifications

• Master's degree in Mechanical Engineering, Electronics, Robotics, or a related technical field.
• 3+ years of non-internship professional experience in hardware testing, validation, or a related hands-on engineering role
• Proven experience designing and building test setups for mechanical or electro-mechanical systems
• Scripting proficiency in Python for test automation, device control, or data analysis
• Demonstrated ability to work independently in a workshop environment using common hand and power tools safely
• Experience with test plan development, execution, and structured reporting of results

Responsibilities

• 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.

Job description

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.

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, RIVR, part of Amazon 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.
