As a Senior Thermal Engineer supporting Surgical R&D, you will be trusted to lead thermal analysis and design efforts for ophthalmic surgical consoles and diagnostic systems. In this role, a typical day will include: Lead thermal analysis and design of systems for surgical consoles and diagnostic devices, defining thermal management roadmaps from component to system level. Plan and execute simulation projects using advanced CFD tools (FloEFD, Fluent, Star-CCM+) and apply first-principles physics to accelerate product development and reduce time-to-market. Develop and execute test plans, manage instrumentation setup, and analyze data to validate models against experimental outcomes. Provide technical insight for system architecture decisions, risk assessments, and early design guidance to minimize thermal and mechanical issues. Mentor cross-functional teams on thermal and fluid principles, collaborating to align with product goals and ensure on-time project completion. Conduct advanced research on thermal behavior, material properties, and heat transfer paths; apply constitutive thermal models for board-level and system-level analysis leveraging ECAD. Deliver executive briefings, design reviews, and comprehensive reports to stakeholders. Innovate by developing new capabilities and incorporating AI/ML techniques (e.g., regression models, neural networks, reinforcement learning) for simulation acceleration and enhanced thermal management strategies.
