About the role

Key responsibilities & impact

Solve technical problems in robot development where requirements, root causes, feasibility, or solutions are unclear
Define target states and constraints, distinguish facts from hypotheses, and develop candidate solutions from mechanics, mechanisms, materials, manufacturing, and related principles
Plan and conduct prototyping, measurement, experiments, and evaluations using internal and external resources
Lead changes to mechanisms, configurations, components, and manufacturing methods when existing approaches are insufficient
Own problems from identification and direction through implementation, validation on actual hardware, and recurrence prevention
Decide mechanical system architecture, key interfaces, and performance allocation for robots, learning-data collection devices, and related systems
Collaborate with electrical, controls, and software specialists on system design issues
Account for component sourcing, manufacturing, and assembly constraints from prototyping through production and ongoing operation
Investigate failures, validate performance, reliability, and maintainability, and confirm countermeasure effectiveness
Provide technical support, design reviews, mentoring, and guidance to development engineers
Lead resolution of cross-team critical issues and technical decision-making for the robot system
Communicate technical risks and validation results and align stakeholders on priorities, resources, and direction
Document reusable design rationale, failure cases, and evaluation methods
Perform hands-on design, assembly, experiments, and hardware evaluation

Requirements

What you’ll need

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, electrical components, wiring, and thermal management, and ability to discuss system-level issues with electrical, controls, and software engineers
Extensive hands-on experience developing robots, mechatronic systems, or complex mechanical equipment, including ownership from concept through evaluation on physical hardware
Track record of solving unprecedented technical problems through self-generated hypotheses, prototyping, and experiments
Experience leading multidisciplinary technical problems and contributing through design reviews and technical guidance
Ability to turn unknowns and failures into concrete validation tasks and persist until solved
Ability to work across needed areas, incorporate specialist insights, and update hypotheses and designs based on experimental results
Willingness to take responsibility for the whole robot working through personal technical output and support of others
Ability to hold technical discussions and negotiations with domestic and international suppliers and drive internal technical discussions and collaboration in English
