We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it’s not.
Your Charter
Define what human-level performance means in quantitative, engineering-relevant terms and translate those insights into specifications that guide the development of humanoid robots.
You will study biological systems to understand how they generate force, absorb energy, sense contact, maintain stability, and adapt to changing environments. From those observations, you'll develop performance models, scaling laws, and engineering targets that influence the design of actuators, sensors, materials, mechanisms, and control systems.
As a Biomechanics Researcher, your work will help ensure that engineering decisions remain grounded in the realities of biological performance rather than arbitrary technical metrics.
Key Outcomes
- Develop quantitative performance models that define human-level capability across locomotion, manipulation, sensing, and physical interaction
- Establish engineering specifications and benchmarks derived from biological systems that directly influence hardware and software development
- Design and execute experiments that reveal the mechanisms underlying biological performance and adaptation
- Identify performance gaps between robotic systems and biological reference systems, providing actionable guidance for closing them
- Enable cross-functional teams to make better design decisions by translating biological insights into practical engineering constraints and opportunities
Key Competencies
- Deep expertise in biomechanics and biological performance analysis
- Ability to translate biological observations into engineering models, specifications, and design requirements
- Strong experimental mindset with experience designing, instrumenting, and analyzing complex physical systems
- Ability to work effectively across multiple disciplines including robotics, controls, materials, sensing, and mechanical systems
- Intellectual rigor combined with the ability to operate effectively in highly ambiguous research environments
Minimum Requirements
- PhD in Biomechanics, Biomedical Engineering, Mechanical Engineering, or a closely related field with 5+ years of experience.
- Demonstrated expertise beyond descriptive biomechanics, with a focus on modeling, quantitative analysis, or engineering applications
- Strong secondary background or hands-on experience in robotics, controls, materials, mechanical systems, or related engineering disciplines
- Proven ability to translate biological insights into actionable engineering specifications or performance targets
- Strong experimental experience, including test design, instrumentation, data collection, and analysis
Preferred Skills
- Experience developing quantitative models of biological motion, force generation, sensing, or adaptation
- Experience working with robotics, electromechanical systems, or advanced hardware platforms
- Familiarity with CAD, simulation environments, and engineering analysis tools
- Strong proficiency in Python or similar tools for modeling, analysis, and scientific computing
Experience studying biological materials, soft tissues, tactile systems, or locomotion dynamics
