About the position

The HV Battery ESS (Energy Storage System) Sr Lead Mechanical/Structural Engineer will play a crucial role in the integration of externally sourced energy storage systems into International brand commercial vehicles. This position involves collaboration with suppliers and TRATON partners to ensure the mechanical engineering aspects of the battery systems are effectively integrated with vehicle chassis, providing necessary protection and performance throughout the vehicle's lifecycle. The role is hybrid, based in Rochester Hills, MI, Lisle, IL, or San Antonio, TX.

Responsibilities

• Creation and management of the mechanical interface control document for the ESS
• Identify, understand and implement mechanical design requirements stemming from governmental, industry, and International brand standards
• Develop electrical, mechanical and thermal interfaces, and ensure package compatibility for cells and modules into HV ESS
• Design or evaluate suppliers' design of components using engineering techniques and knowledge of manufacturing process to ensure the most efficient and cost-effective design
• Work with the Vehicle Architecture team to define the ESS packaging envelopes and reconcile with internal component and cell packaging, Noise Vibration Harshness (NVH), enclosure rigidity, safety, aerodynamic, and other vehicle & pack requirements
• Work closely with other functions and global teams to meet package, performance and attribute requirements for different vehicle platforms and configurations
• Optimization of the location, attachment, and retentions of cells, components and wiring within the HV battery enclosure with consideration for thermal, EMC, crash, etc.
• Review of supplier Design Failure Mode and Effect Analysis (DFMEAs) and co-development of HV ESS Functional Safety requirements and system DFMEAs
• Support mechanical & environmental portion of pack Design, Valuation, Plan and Report (DVP&R), provide input on test procedures, assess results, and suggest improvements
• Work with suppliers, our TRATON partners, and other International teams to achieve program goals on-time and with high quality
