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.
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.
