Responsibilities

• CFD Modeling & Thermal Analysis: Lead CFD analysis and thermal modeling activities for enclosed industrial systems and modular infrastructure products. Develop airflow simulations for BESS enclosures, modular data centers, power electronics, electrical rooms, and integrated equipment platforms. Analyze airflow distribution, pressure drop, temperature gradients, recirculation zones, hot spots, and thermal rejection performance. Validate system performance under worst-case operating and ambient conditions. Optimize thermal architectures to improve cooling efficiency, reliability, acoustics, and manufacturability.
• Cooling System Design & Airflow Management: Design and integrate cooling systems based on actual equipment heat loads and operational requirements. Develop enclosure airflow strategies including intake/exhaust placement, ducting, baffles, plenums, circulation paths, and pressure balancing. Select and integrate off-the-shelf cooling equipment including HVAC units, heat exchangers, fans, chillers, and thermal management systems. Design for real-world operating environments including dust, humidity, vibration, solar loading, and extreme ambient conditions. Ensure designs meet thermal performance targets without excessive cost, noise, or packaging complexity.
• Mechanical System Design & Product Development Support: Support mechanical packaging and enclosure design activities related to thermal system integration. Coordinate thermal system layouts with structural, electrical, and manufacturing constraints. Develop CAD models, engineering drawings, and BOMs supporting thermal and mechanical integration. Ensure designs support manufacturability, serviceability, maintenance access, and production scalability.
• Testing, Validation & Product Performance: Support prototype testing, heat runs, thermal validation, and system troubleshooting activities. Correlate CFD models with physical testing data and refine simulations accordingly. Analyze field performance data to identify opportunities for thermal improvement. Participate in Root Cause Analysis for overheating, airflow imbalance, thermal failures, or reliability concerns.
• Cross-Functional Engineering Collaboration: Partner closely with Electrical Engineering, Structural Engineering, Manufacturing Engineering, NPI, and Operations teams. Support customer technical discussions related to cooling performance and thermal design strategy. Work with manufacturing teams to ensure thermal solutions align with fabrication and assembly capabilities. Support supplier selection and technical evaluation of cooling system components and technologies.
• Design for Manufacturing (DFM) & Continuous Improvement: Drive DFM initiatives focused on scalable thermal system integration and assembly efficiency. Reduce unnecessary complexity while maintaining thermal performance and reliability targets. Standardize cooling architectures, airflow strategies, and thermal design methodologies where appropriate. Contribute to engineering standards, calculation templates, and best practices for CFD and thermal analysis.
• Technical Leadership: Serve as a subject matter expert for CFD analysis, airflow management, and thermal systems engineering. Mentor junior engineers and support development of internal thermal engineering capability. Influence system-level product architecture and cooling strategies across multiple programs.
