• Based on your in-depth understanding of thermal transport phenomenon, propose practical new design concepts to help Ambri achieve our product goals
• Lead thermal efforts to scope, define, solve, implement and validate designs
• Lead thermal design of thermal test verification activities for materials and system operation
• Work with mechanical, electrical, software, and manufacturing engineering disciplines to ensure overall system requirements are cost effectively being meet
• Derive thermal conditions of energy storage system for a range of operating conditions including the effects from charge/discharge at various c-rates and rest periods
• Perform quick ‘rough estimate’ calculations to quickly verify thermal models and concepts during collaborative design meetings
• Take responsibility for design activities, ensure solution meets requirements, and execution meets schedule requirements
• Specifically select material, and components to ensure adherence to thermal requirements are met
• Prepare design review materials and participate in design reviews
• Work with Program Management on estimating project effort, reporting on project progress and task execution
• Execute worst case analysis on design to meeting company quality standards
• Perform and review DFMEA analysis activities on systems to verify system performance to requirements
• Conduct modeling of electronic systems and thermal management solutions using FEA, CFD, and analyzes based on first principles
• Specify thermal management solutions for high power, high heat flux electronic assemblies
• Design thermal test set-ups and execute testing programs
• Prepare proposals contributing to conceptual thermal designs, costs & performance estimates
• Manage customers, suppliers and sub-contractors of thermal management solutions to schedule and technical performance

**Requirements: **

• Must have at least a BSME degree, MSME or higher preferred.
• Demonstrated excellent problem solving skills
• Minimum 20 years of thermal modeling, specifying, and testing thermal systems and thermal management solutions
• Knowledge of heat transfer, thermal management, and cooling of electronics.
• Experience using Solidworks CAD software (or equivalent) to do thermal modeling/geometry modeling
• Experience in cooling systems with a large number of battery cells and electronic assemblies
• Experience using thermal simulation software for transient and steady state analysis.
• Deep knowledge of thermal behavior and heat dissipation within electrical systems.
• Demonstrated excellent problem solving skills
• Must have excellent English written and oral communication skills
• Demonstrated ability of working well within a team and independently to achieve results
• Familiarity with electrical board layout to ensure component placement is optimized for thermal considerations.  This includes analyzing junction temperatures and component temperatures on PCBA
