Mechanical Engineer - Interconnect & Tendon Systems

1X Technologies AS • San Carlos, CA

13d • Onsite

About The Position

The Robot Interconnect and Tendon Systems team develops the soft goods, harnessing, tendon routing, and compliant mechanical systems that enable reliable motion, durability, and integration across humanoid robotic platforms. A key focus area for the team is the development of foot soft goods systems that must withstand demanding real-world loading, wear, environmental exposure, and continuous robotic operation while remaining lightweight and manufacturable at scale. You’ll work closely with mechanical, industrial design, manufacturing, and integration teams to rapidly prototype, test, and refine foot soft goods assemblies and interconnect systems that are critical to overall robot reliability, mobility, and long-term performance.

Requirements

• 2–4 years of experience in mechanical engineering, soft goods product development, wearable products, robotics, or consumer hardware.
• Hands-on experience designing, prototyping, and testing soft goods or textile-based assemblies.
• Proficiency with CAD tools and engineering documentation workflows.
• Experience working closely with prototype fabrication, assembly, or manufacturing processes.
• Bachelor’s degree in Mechanical Engineering or related technical field.

Nice To Haves

• Experience with harness systems, sewn assemblies, rope- or cable-driven systems, tendon routing systems, or compliant mechanisms.
• Background working with suppliers or contract manufacturers on soft goods development.
• Experience designing fixtures, jigs, or test setups for product validation.
• Exposure to robotics, footwear, wearable technology, or high-reliability consumer hardware products.
• Familiarity with rapid prototyping methods and iterative product development workflows.

Responsibilities

• Support the design, prototyping, integration, and validation of foot soft goods systems for humanoid robotics platforms.
• Develop durable, manufacturable, and reliable assemblies including harnesses, tendon interfaces, sewn components, and compliant structures that integrate seamlessly into robotic systems while enabling rapid iteration and scaling toward production.
• Design and release foot soft goods assemblies, harnesses, tendon routing components, and sewn systems that meet durability, integration, and manufacturability requirements.
• Execute structured testing and validation efforts to identify wear patterns, failure modes, and reliability risks, driving measurable design improvements.
• Develop and maintain CAD models, drawings, BOMs, and documentation to support prototype and production builds.
• Partner effectively with vendors and internal manufacturing teams to improve assembly quality, repeatability, and production readiness.
• Support rapid prototyping and iterative hardware development cycles while maintaining high attention to detail and execution quality.

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
• 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
• Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
• Commuter benefits (transit and parking)
• Short-term and long-term disability, and life insurance
• Employee Assistance Program (EAP) for mental health, financial, and personal support
• Onsite snacks and catered lunches
