About this role

Our Mission

    Accelerate the irreversible expansion of robotics into reality.

Position Summary

    Our mission is to make robotics an irreversible reality. We are always interested in connecting with talented Mechanical Engineers who are passionate about building innovative robotic systems including humanoids..

    Our team develops advanced robotics solutions across a variety of applications, including humanoid robots, mobile manipulation, logistics automation, retail automation, and intelligent machines. Depending on experience and interests, you may contribute to mechanical design, mechatronic integration, prototyping, testing, manufacturing, and product development.

    Our current focus is the next generation of articulated robots, including humanoids. We run an in-house “data foundry” that captures large-scale, real-world manipulation data to train our robot foundation models, so the hardware you design directly shapes what our models can learn. Over the coming year we are moving from prototypes to deploying next-generation humanoids in the field, and we are looking for hardware engineers to own that journey from bench to real-world fleet.

    This is an open role intended for engineers at all experience levels, from early-career engineers to experienced technical leaders.

What you'll work on

  • Design and develop mechanical systems and components for robotic products.

  • Create CAD models, assemblies, and engineering documentation.

  • Collaborate with electrical, controls, software, and product teams to develop integrated robotic systems.

  • Support actuator, transmission, sensor, and structural system design.

  • Build, test, and iterate prototypes to validate performance and reliability.

  • Conduct engineering analyses, including structural, thermal, kinematic, and tolerance studies.

  • Improve product reliability, manufacturability, serviceability, and cost efficiency.

  • Support product transition from prototype to production.

  • Work with suppliers and manufacturing partners to scale hardware development.

What We're Looking For

  • Background in Mechanical Engineering, Mechatronics, Robotics, or a related field.

  • Experience developing electromechanical products or robotic systems.

  • Experience in designing moving mechanisms with gears, racks, LM guides, belts, and gearboxes. 

  • Practical experience in 2D drawings for both sheet metal and machined parts.

  • Proficiency with CAD tools such as SolidWorks, Creo, CATIA, NX, or equivalent.

  • Understanding of mechanical design principles, materials, manufacturing processes, and product development.

  • Strong problem-solving skills and ability to work in cross-functional teams.

Preferred Experience

    Experience in one or more of the following areas:

  • Robotics and automation systems

  • Manipulators and motion systems

  • Mobile robots, AMRs, or AGVs

  • Warehouse and logistics automation

  • Humanoid robotics

  • Retail or service robotics

  • Industrial equipment and machinery

  • Automotive, aerospace, or other complex electromechanical products

  • Design for Manufacturing (DFM) and Design for Assembly (DFA)

  • Prototype development and production scaling

Why Join Us

    You will have the opportunity to work on challenging robotics problems, collaborate with multidisciplinary teams, and help bring next-generation robotic systems from concept to real-world deployment.

    We welcome applications from engineers at all career stages. The scope and level of responsibility will be aligned with your experience and expertise.

Language

  • Professional proficiency in English and Japanese required.
