Biomechanics Researcher

The role

You will study biological systems to understand force generation, energy absorption, sensing, stability, and adaptation. You will develop performance models, scaling laws, and engineering targets to guide the design of humanoid robots.

What you will do

• Develop quantitative performance models for locomotion, manipulation, sensing, and physical interaction
• Establish engineering specifications and benchmarks derived from biological systems
• Design and execute experiments to reveal mechanisms of biological performance and adaptation
• Identify performance gaps between robotic systems and biological reference systems
• Translate biological insights into practical engineering constraints and opportunities for cross-functional teams

Required qualifications

• 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

Nice to have

• 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

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
• 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
• Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
• Commuter benefits (transit and parking)
• Short-term and long-term disability, and life insurance
• Employee Assistance Program (EAP) for mental health, financial, and personal support
• Onsite snacks and catered lunches
