• Mechanical design and vehicle integration of power electronic enclosures and or thermal systems including implementation of sealing and venting strategies.


• Perform design activities such as


• Module design and development (cell mounting, spacing, connecting, cooling)


• Mechanical / structural design (durability, crash, light weighting)


• Integration of electrical systems and components (fuses, contactors, wiring)


• Cooling system design for thermal management


• Production release and development cycle experience


• Interface with suppliers to execute supplier quality processes such as PPAP


• BOM management / reporting


• Change management


• Documentation and report creation


• Create 2D drawings based on parametric CAD models per ANSI and ISO standards


• Datum strategies, Geometric Dimensioning & Tolerance (GD&T), Stack up Analysis, Design for Manufacturing and Design for Assembly.


• Work closely with and lead cross functional team members (vehicle, modeling and simulation, software, functional safety)


• Communicate project progress to leadership and manage project risk


• Prepare for and participate in formal and informal design review activities


• Coordinate design activities with global partners
