About The Position

Humanoid is hiring a Senior Prototype Engineer for its Hardware team in Boston. The role focuses on hands-on iteration, assembly, diagnosis, and evolution of advanced robotic platforms for real-world use, including the HMND-01 humanoid platform. The engineer will troubleshoot complex electrical issues, work across disciplines on prototype design and bring-up, document lab processes, develop reusable cable assemblies and test equipment, and improve product and process performance.

Requirements

• Demonstrated experience in rapid physical prototyping, hands-on debugging of custom hardware, and troubleshooting complex electrical systems in robotics or similar domains.
• Working knowledge of low-voltage and mixed-signal circuits, connectors, sensors, and compact electromechanical systems.
• Experience communicating concisely through documentation such as procedures, test plans, diagnostics, and lessons learned.
• Ability to collaborate across mechanical, electrical, and software engineering disciplines to solve urgent, ambiguous issues.
• Comfort working in a high-velocity, high-ambiguity startup environment where priorities shift quickly.

Nice To Haves

• Experience designing for manufacturability and reliability in human-sized or mobile robotics.
• Familiarity with automated test and diagnostic tools used in modern hardware labs.

Responsibilities

• Lead troubleshooting and resolution of complex electrical issues in prototype humanoid robots, including operational and in-development systems.
• Perform detailed failure analysis and share findings with hardware and software engineering teams.
• Collaborate with multidisciplinary engineers on prototype design, assembly, and bring-up, particularly for high-density electromechanical integrations.
• Create, maintain, and execute test procedures, troubleshooting guides, and repair runbooks for the prototyping lab.
• Design, document, and iterate on cable assemblies, test jigs, and harnesses for repeated use on dynamic robotic platforms.
• Identify and lead process and product improvements to minimize downtime and improve testing and repair efficiency.
• Contribute feedback across design, build, and test to improve first-pass yield and manufacturability.

Benefits

• Comprehensive health coverage for US-based employees, including fully paid medical, dental, and vision insurance.
• Virtual care and employee assistance resources.
• 23 days of accrued PTO, separate sick leave, and paid company holidays.
• 401(k) retirement plan with a 4% employer match.
• Equity.
• Free daily catered lunch, snacks, and drinks in-office.
