Key Responsibilities:

• Lead initiatives to refine the fitting process and shoe profile characteristics, ensuring improved alignment between user anatomy and shoe geometry.
• Analyze biomechanical data to enhance shoe customization parameters, focusing on pressure distribution, joint kinematics, and movement patterns.
• Research and develop advanced methods for foot scanning, gait analysis, and movement tracking to capture high-fidelity input data for footwear fitting algorithms.
• Design and manage experimental setups for biomechanical testing, including walking, running, and standing scenarios across various terrains and user demographics.
• Design and manage controlled lab-based experiments for comprehensive shoe performance testing, including durability, flexibility, stiffness, and energy return metrics.
• Collaborate with external labs to perform unbiased third-party testing, ensure proper protocols, and interpret test results to validate biomechanical hypotheses.
• Assist in footwear simulation modeling to evaluate long-term wear processes, pressure points, and potential failure areas through virtual prototyping and digital twin approaches.
• Define and maintain classification systems for different types of footwear based on their mechanical, structural, and performance-related characteristics.
• Develop methods and criteria to assess and quantify these parameters through both subjective user feedback and objective mechanical testing.
• Support the integration of biomechanical insights into design software tools, enabling automated adjustments and smart recommendation systems.
• Collaborate cross-functionally with design, material science, and product engineering teams to ensure biomechanical findings directly inform product development.
• Stay up to date with advancements in wearable sensor technology, musculoskeletal modeling, and sports science to inform long-term research strategy.

Skills & Experience:

• Strong background in human anatomy and biomechanics.
• Extensive experience in data collection, motion analysis, and fit evaluation.
• Deep understanding of materials and mechanical properties as they relate to footwear performance.
