Senior Hardware Test Engineer

Sinceits 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 worlds most talented individuals. Every part of our robots is designed and produced in-housefrom motor coils to AIreflecting our vertically integrated approach. At 1X, youll 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.

As we scale from research and development to full-scale manufacturing, we are seeking aSenior Hardware Testing Engineerto own and leadreliability testingefforts. In this role, you will focus on ensuring the long-term performance and durability of our robotic systems, identifying potential failure points, and driving improvements to increase reliability at scale.

RESPONSIBILITIES

• Design, implement, and managereliability testing protocolsfor robotic hardware, including environmental, mechanical, electrical, and lifecycle tests.
• Leadroot cause analysis (RCA)for hardware failures, working cross-functionally with mechanical, electrical, and firmware teams to resolve issues.
• Developautomated test rigsand systems to perform continuous reliability testing of key robotic subsystems (e.g., joints, actuators, sensors).
• Create and maintaindetailed test documentation, including test plans, procedures, and reports, ensuring clear communication of test results and recommendations.
• ConductHighly Accelerated Life Testing (HALT)andHighly Accelerated Stress Screening (HASS)to proactively identify weak points in design.
• Collaborate with design teams to implementDesign for Reliability (DfR)principles, ensuring robust designs that can withstand real-world use.
• Evaluate and trackfailure modes and effects analysis (FMEA)results, recommending improvements to reduce risk of failure.
• Work closely withmanufacturing partnersto ensure that reliability testing is part of the production process, identifying and mitigating risks during scaling.
• Stay up to date withreliability standardsand best practices across industries to ensure our testing processes are world-class.
• Providetechnical mentorshipto junior team members and build a culture of continuous improvement within the hardware testing team.

• 3+ years of experiencein hardware testing and reliability engineering, with a focus on complex electromechanical systems.
• Expertise inreliability testing methodologies, including environmental, mechanical, and electrical stress tests.
• Strong knowledge ofroot cause analysis (RCA)methods and tools, such as8D,Fishbone, or5 Whys.
• Experience designingcustom test rigsfor automated and long-term testing.
• Familiarity withFMEAand experience improving product designs based on reliability data.
• Proficiency withdata acquisition toolsandtest automationplatforms.
• Strong communication and documentation skills, with the ability to clearly present test results and recommendations.
• Bachelors or Masters degree inMechanical Engineering, Electrical Engineering,or a related field.

Preferred Qualifications

• Experience inrobotics,automotive,consumer electronics, or other industries withcomplex electromechanical systems.
• Knowledge ofenvironmental and regulatory standards(e.g., IP ratings, thermal cycling, vibration testing).
• Knowledge ofsensor integrationandactuator performance testing.
• Familiarity withPCB-level reliability testing.
• Experience working withglobal manufacturing partnersto ensure reliability at scale.
• Familiarity withdata analytics toolsto track and analyze reliability data trends.

We encourage you to apply even if you do not meet every single qualification.
