Humanoid in Boston is seeking a Senior Robotics Prototype Engineer to rapidly iterate, assemble, diagnose, and evolve advanced robotic platforms for real‑world use. This hands‑on role sits on the Core Platform team and requires comfort with fast timelines and ambiguous problems.

You will partner with mechanical, electrical, and software engineers to design, build, and bring up prototype systems, create clear test procedures, and drive manufacturability and reliability in mobile robots.

Qualifications

• Experience troubleshooting complex electrical issues in prototype robotics.
• Collaborate with mechanical, electrical and software engineers on prototyping.
• Ability to create and follow test procedures and repair runbooks.
• Experience with rapid physical prototyping and hand-on debugging.
• Familiarity with low‑voltage and mixed‑signal circuits.

Responsibilities

• Lead troubleshooting of complex electrical issues in prototype robots and share findings with teams.
• Collaborate on prototype design, assembly, and bring‑up with multidisciplinary engineers.
• Create and maintain test procedures, troubleshooting guides, and repair runbooks.
• Design and iterate on cable assemblies, test jigs, and harnesses for repeated use.
• Identify opportunities to improve processes, downtime, and test efficiency.
• Support feedback loops across design, build, and test to improve yield and manufacturability.
• Demonstrate rapid physical prototyping and hands‑on debugging of hardware.
• Communicate clearly through documentation of procedures, plans, and diagnostics.

Job description

Here at Humanoid, we believe in a future where robots amplify human potential. That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND‑01 Alpha—our rapidly developed humanoid platform now running in real industrial pilots—and we’re growing the team to take it even further.

About The Role

We’re hiring a Senior Robotics Prototype Engineer to join our Core Platform team based in Boston. This is a hands‑on role where you will rapidly iterate, assemble, diagnose, and evolve advanced robotic platforms for real‑world use.

What You’ll Do

• Lead troubleshooting and resolution of complex electrical issues in prototype humanoid robots, including operational and in‑development systems; perform detailed failure analysis and share learnings with hardware/software engineering teams.
• Collaborate closely with multidisciplinary engineers on prototype design, assembly, and bring‑up, especially high‑density electromechanical integrations.
• Create, maintain, and execute clear test procedures, troubleshooting guides, and repair runbooks for the prototyping lab to ensure high standards and rapid iteration cycles.
• Design, document, and iterate on cable assemblies, test jigs, and harnesses optimized for repeated use on dynamic robotic platforms.
• Identify and own opportunities for continuous process and product improvement—minimizing downtime and improving test/repair efficiency.
• Contribute to robust feedback loops across design, build, and test, driving first‑pass yield and manufacturability.
• Demonstrated experience in rapid physical prototyping, hands‑on debug 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.
• Track record communicating concisely via documentation—procedures, test plans, diagnostics, and lessons learned.
• Adept collaborating across mechanical, electrical, and software engineering boundaries to solve urgent, ambiguous issues.
• Comfortable in a high‑velocity, high‑ambiguity startup setting where priorities shift fast.
• Experience designing for manufacturability and reliability in the context of human‑sized or mobile robotics is a plus.
• Familiarity with automated test and diagnostic tools used in modern hardware labs.

What We Offer:

• Comprehensive health coverage for US‑based employees, including fully paid medical, dental, and vision insurance, with virtual care and employee assistance resources.
• Meaningful time off to rest and recharge: 23 days of PTO (accrued), separate sick leave, and paid company holidays.
• 401(k) retirement plan with employer match.
• Equity included–we believe builders should share in what they build.
• Free daily catered lunch, snacks, and drinks in‑office.
• Collaboration with top‑tier engineers, researchers, and product experts in AI and robotics.
• Freedom to influence the product and own key initiatives.

For this role in Massachusetts, the expected base salary range is $115K–$160K USD per year; your placement in that range depends on how your experience maps to our internal leveling.
