Test Engineer, Robotics

Target start date: Immediately. Relocation provided.

Since its founding in 2015, 1X has been at the forefront of developing advanced humanoid robots designed for household use. Our mission is to create an abundant supply of labor via safe, intelligent humanoids.

We strive for excellence in all we do, solving some of the hardest problems in robotics with the world’s most talented individuals. Every part of our robots is designed and produced in-house—from motor coils to AI—reflecting our vertically integrated approach. At 1X, you’ll own real projects, be recognized for your achievements, and rewarded based on merit.

We are seeking a Robotics Test Engineer to join our team at the Hayward manufacturing facility. In this role, you will focus on mechanical and electromechanical validation of our humanoid robots, ensuring their reliability, safety, and performance through rigorous sub-system and end-to-end testing. You will design test plans, build custom test setups, execute experiments, and collaborate across hardware and software teams to resolve system-level issues. This is a hands-on role ideal for someone who thrives on first-principles thinking and detailed technical execution.

Responsibilities

• Lead and support software bring-up for new robotic hardware including sensors, actuators, and embedded systems

• Integrate and validate firmware, middleware, and control software modules on humanoid platforms

• Develop and maintain automated test frameworks for software validation, hardware-in-the-loop (HIL) testing, and end-of-line manufacturing tests

• Design and execute functional and performance tests for locomotion, perception, manipulation, and other robotic subsystems

• Collaborate with mechanical, electrical, and software engineering teams to debug system-level issues

• Build tools and infrastructure to monitor robot behavior, collect logs, and track test results

• Document integration and test procedures and contribute to best practices for continuous testing and deployment

• Bachelor’s or Master’s degree in Robotics, Computer Engineering, Electrical Engineering, or a related field

• 2+ years of experience in robotics software integration, embedded systems, or test automation

• Proficiency in C++, Python, and Linux-based development environments

• Experience with ROS/ROS2, real-time systems, and embedded communication protocols (CAN, I2C, SPI, UART)

• Familiarity with test automation tools, CI/CD pipelines, and version control systems such as Git

• Strong debugging skills across hardware/software interfaces

• Experience with manufacturing test systems and end-of-line testing processes

• Exposure to hardware-in-the-loop (HIL) simulation and real-time testing frameworks

Nice to have

• Prior experience working with humanoid or legged robots

• Background in fast-paced startups or hardware prototyping environments

Compensation
At 1X your work and results will be rewarded with a total rewards package consisting of a base salary, stock options and benefits. Base salary range is $90,000 to $150,000. Your actual salary will be based on your knowledge, skills and experience.

Location Policy
We believe the best work is done when collaborating and therefore require in-person presence in our office locations.
