• Translate system-level thermal challenges into physics-based models using FEA/CFD to solve electro-thermal, thermo-mechanical, and fluid-thermal problems under real-world conditions.
• Drive thermal design optimization for high-power-density systems, balancing temperature, pressure drop, signal integrity, and manufacturability.
• Support material and interface strategies (TIMs, high-conductivity alloys, advanced polymers/composites) to ensure performance and reliability under thermal cycling, aging, and environmental stress.
• Establish thermal design standards and best practices, including thermal resistance networks, contact/interface heat transfer, airflow and liquid cooling integration, and thermal distortion/tolerance stack-up effects.
• Standardize methodologies and scalable models to enable reusable simulation frameworks, digital twins, and cross-platform design libraries.
• Support innovation in next-generation cooling solutions, including liquid cooling, co-packaged optics integration, high-current connector thermal management, and AI-driven optimization. 

3. Cross-Functional Integration 

• Collaborate with electrical (SI/PI), mechanical, and manufacturing teams to co-optimize system performance, packaging density, and thermal solutions. 

4. Validation, & Governance 

• Lead thermal model validation and correlation through lab testing (IR thermography, thermocouples, wind tunnel), model calibration, and development of design margins and derating guidelines.
• Support design governance and technical reviews (DFMEA, PFMEA), ensuring robust multiphysics considerations in product decisions. 

5. Leadership & External Engagement 

• Mentor engineers and build domain expertise in thermal sciences, multiphysics simulation, and physics-based design.
• Represent the organization externally with customers, industry forums, and standards bodies on advanced thermal challenges.
