Overview Join to apply for the

Test Engineer, R&D

role at

1X .

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

We are seeking a versatile and hands-on Robotics Test Engineer to join our new, high-impact test team. This is not a traditional, siloed testing role. You will be a key player in our engineering organization, working at the intersection of hardware, firmware, and software. Your mission will be to ensure our robots are robust, reliable, and ready for the real world by supporting the full product lifecycle—from early-stage R&D characterization to final production validation.

Responsibilities

Test Development & Automation: Design, develop, and maintain robust, scalable test automation frameworks in Python and C++; Architect and build custom hardware-in-the-loop (HIL) test systems and mechanical/electrical test fixtures to simulate real-world conditions.

Test Planning & Documentation (The Foundation): Author and maintain clear, concise test plans, test procedures, and test cases based on product requirements and technical specifications; Develop and manage test matrices to ensure adequate coverage across different hardware, software, and firmware configurations; Create detailed, data-driven test reports that communicate results and risks to both technical and non-technical stakeholders; Maintain traceability from system requirements to test case execution and results.

Hands-On Testing & Debugging: Execute a wide range of tests, including Exploratory & Characterization Testing on new R&D prototypes, Performance & Reliability Testing, and System-Level Verification & Validation against formal requirements; Lead debugging and root cause analysis of complex, multidisciplinary issues that span the entire robotics stack; Become a system-level expert in how subsystems interact to deliver product features.

Qualifications & Experience: 3+ years in a test engineering, systems integration, or related role; strong programming proficiency in Python and/or C++; hands-on experience with oscilloscopes, logic analyzers, multimeters, and power supplies; solid understanding of embedded systems, microcontrollers, and communication protocols (e.g., CAN, I2C, SPI); experience with version control systems, particularly Git; excellent problem-solving skills and a methodical, data-driven approach to debugging.

Nice to have

Experience working with test automation frameworks

Experience with Real-Time Operating Systems (RTOS) and Linux environments

Experience with CAD software (e.g., SolidWorks, Onshape) for designing test fixtures

Familiarity with agile project management tools (e.g., Jira, Confluence)

A genuine passion for robotics and building things
