Actuator Test & Equipment Engineer – Generalist Intelligent Robots

Job summary

At Rho***, we’re building the next generation of generalist intelligent robots. We own the full robotics stack from high-performance hardware and robot systems to the infrastructure and state-of-the-art foundation world models that control our robots.

Qualifications

• sample rates, sensor accuracy, synchronization, filtering, storage — in close partnership with the modeling engineer.
• The data you collect must be good enough to validate models and inform design decisions, not just good enough to look at.
• Test Execution & Throughput: Work closely with the actuator technician to make sure tests are run promptly and efficiently.
• Build the procedures, fixtures, and software tooling that turn a test stand into a high-throughput piece of capital equipment rather than a one-off experiment.
• Test Plan Development: Partner with design and modeling engineers to define test plans for component characterization, model correlation, and durability validation.
• Push back when a plan won't actually answer the question being asked.
• Data Integrity & Reporting: Own the integrity of the data leaving your test stands — calibration, traceability, uncertainty quantification — and the clarity of the reports that go back to design and modeling.
• WHAT YOU'LL BRING
• Education: Bachelor's degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or a related field.
• Experience: 5+ years developing and operating test equipment for electromechanical systems — motors, drivetrains, actuators, transmissions, or similar.
• At least one program where you owned a test capability from blank sheet through routine production use.
• Core Fundamentals: Strong grasp of the physics being measured — motor torque-speed behavior, gear efficiency, heat transfer, vibration — and the instrumentation that captures it.

Responsibilities

• As an Actuator Test & Equipment Engineer, you will design, build, and operate the test infrastructure that turns actuator models into validated hardware.
