Robot Hardware Engineer (Mechanical)

About the role

A position building the “body” of Muso-roid, our general-purpose robot worker. You will own hardware end to end — from selecting and developing robots, cameras, and robot hands to peripheral equipment and data-collection devices.

The crossover between physical AI and established robotics requires technology that does not yet exist anywhere. Hardware in particular is highly challenging: data collection is a whole new workload, and the new use cases physical AI unlocks come with hardware requirements of their own.

Responsibilities

• Select and develop hardware such as robots, cameras, and robot hands
• Develop peripheral equipment for robots
• Develop data-collection devices

Why this role

• Join right after our seed round and take part in technology selection and development across our entire robotics stack
• Build technologies that do not yet exist, at the crossover of physical AI and established robotics
• Work on the front line of unprecedented hardware requirements, from data-collection devices to use cases unique to physical AI

Required

• 3+ years of professional experience in hardware development
• Professional experience in mechanical design
• Practical experience ordering machined parts

Nice to have

• Experience developing robots of any kind, including non-commercial ones
• Experience developing robot grippers
• Professional experience in circuit design
• Experience developing factory-automation (FA) equipment
• Development experience using actuators
• Experience with offline teaching or simulation
• Understanding of functional safety
• Experience with industrial robots, PLCs, or industrial machinery
• Experience using AI in hardware development

Who we're looking for

• You design hardware use-case first
• You reason rationally from basic science, engineering, and hands-on experience
• You balance flexibility toward new use cases and requirements with an uncompromising grip on what must never slip, such as safety

Employment & salary

• Employment: full-time
• Salary: 8M–16M JPY (depending on experience and skills)
• Working style: discretionary labor system for professional work

Location

Daini TOC Bldg. 6F, 7-21-11 Nishi-Gotanda, Shinagawa-ku, Tokyo

Benefits

• Two days off per week (Sat/Sun) and national holidays
• 20 days of paid leave, granted from the first year
