Test Engineer, Manufacturing
Location: Hayward, CA (on‑site)

About 1X
We’re an AI and robotics company based in Palo Alto, California, on a mission to build a truly abundant society through general‑purpose robots capable of performing any kind of work autonomously.
We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. That’s why we’re focused on developing friendly home robots designed to integrate seamlessly into everyday life.
We’re looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we’d be thrilled to hear from you and explore how you might contribute to our journey.

Role Overview
You will play a key role in ensuring the performance, safety, and manufacturability of our humanoid robots at our new manufacturing facility in Hayward. This role involves developing and executing quality strategies, analyzing test data, collaborating with engineering teams, and building scalable systems from sub‑components through full robot assemblies. Your work will directly impact product excellence, yield, and customer satisfaction.

Responsibilities

• Develop end‑to‑end quality strategies for robot manufacturing, from subassemblies to full systems

• Conduct PFMEA (Process Failure Modes and Effects Analysis) to identify failure modes and enhance test coverage and process robustness

• Collaborate with test and firmware engineering teams to integrate quality checks into manufacturing workflows

• Analyze test data to monitor station yields and identify root causes of failures

• Collaborate with design teams to implement quality improvements at both component and system levels

• Lead Design of Experiments (DOE) to establish optimized pass/fail limits and improve test accuracy

• Evaluate test station performance and scalability across different production sites

• Document quality plans, testing procedures, and data‑driven corrective actions

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

• 3+ years of experience in electromechanical hardware testing in a manufacturing environment

• Familiarity with PCBA testing, IMU calibration, actuator and sensor validation, or end‑of‑line system testing

• Strong knowledge of PFMEA, Gage R&R (repeatability and reproducibility), and statistical data analysis

• Experience working with test hardware (for example, power supplies, CAN tools, actuators) in production environments

• Self‑starter with strong time management skills and attention to detail

• Proficient in technical documentation and cross‑functional communication

• Nice to have: Experience with autonomous or humanoid robotic systems

• Nice to have: Exposure to scalable test systems across multiple manufacturing sites

• Nice to have: Background in startup or fast‑paced hardware development environments

Benefits & Compensation

• Salary Range: $90,000 – $150,000 per year

• Stock options

• Health, dental, and vision insurance

• 401(k) with company match
