Principal Robotics Hardware Engineer at TELEXISTENCE in Tokyo

Job description

In this role, you will take on challenges in TELEXISTENCE's robot development where the technical approach or feasibility is not yet clear, and drive them to resolution yourself. Grounded in robot hardware development, you will solve problems across all disciplines, not only from the mechanical, electrical, and software perspectives. As a Principal, you are expected to own the full path to solving the problems that block development: defining what needs to be solved, building hypotheses from first principles, exploring approaches, prototyping and experimenting, and feeding the results into the design. Even when no established solution exists, you will find a path to realization through validation, and you will be responsible for delivering hardware that actually works and can be used on an ongoing basis. You will also support engineers in each specialized area on the technical side, and lead both the resolution of critical issues that go beyond individual teams and the technical decision-making for the robot system as a whole. You will also do hands-on design, assembly, and experiments yourself. Key Responsibilities Solving technical problems with no clear path forward For problems where the requirements, root causes, or solutions are unclear, define the target state and constraints, and separate known facts from unverified hypotheses. Return to the underlying principles of mechanics, mechanisms, materials, manufacturing, and related fields to develop multiple candidate solutions. Plan experiments to validate the most critical and uncertain issues, and manage your own work as well as internal and external resources to carry out prototyping, measurement, and evaluation. When an extension of the existing configuration will not work, explore alternatives with stakeholders, including revisiting the requirements, and lead changes to mechanisms, configurations, components, and manufacturing methods. Own the entire process, from identifying problems and proposing direction to implementation, confirming effectiveness on the actual hardware, and preventing the root problem from recurring, so that the team can move on to the next stage of development. System design and development for sustained operation For existing robots, devices for collecting learning data, and other systems, decide the mechanical system architecture, key interfaces, and performance allocation. Work with electrical, controls, and software specialists to resolve design issues. Reflect constraints from component sourcing, manufacturing, and assembly in design decisions, and own the technical side from prototyping through building the required number of units, evaluation, and ongoing operation. Identify the root causes of failures that occur in testing and operation, validate required performance, reliability, and maintainability, and confirm that countermeasures are effective. Technical leadership across teams Provide technical support, design reviews, and mentoring to development team members, including Lead and Expert engineers, and personally take ownership of the hardest problems to chart a path to their resolution. Communicate technical risks and validation results clearly, and bring stakeholders to agreement on development priorities, required resources, and whether to continue or change course. Share the design rationale, failure cases, and evaluation methods gained through problem-solving in a form other members can reuse, raising the organization's problem-solving capability. Requirements: Must-Haves Technical skills 7+ years of hands-on experience making design decisions by combining deep knowledge of mechanisms, drive systems, materials, strength and stiffness, and tolerancing with quantitative analysis and validation on physical hardware. Ability to design with 3D CAD, create drawings, design for manufacturing and assembly, and personally carry out assembly, evaluation, and failure analysis. Understanding of constraints related to sensors, actuators, elec
