**Summary:** As a Battery Product Design Engineer at Meta, you will take ownership of the battery pack designs and their integrations to power the amazing devices developed by the Reality Lab. You will work closely with product engineering teams to define cell and pack requirements, aiming to find the best options for product volume, weight, and run time. Your role will involve researching, designing, evaluating, installing, operating, or maintaining mechanical products, equipment, systems, and processes to meet specific requirements. Your expertise will be crucial in recommending design modifications to eliminate mechanical, machine, and system malfunctions. Additionally, you will conduct research that tests and analyzes the feasibility, mechanical soundness, design, operation, and performance of equipment, components, and systems. Developing test and validation plans for manufacturing and characterizing battery packs will be a key responsibility, along with supporting module and system reliability testing with both internal and external organizations. You will provide build support during New Product Introduction activities to ensure that manufacturing processes align with design intent. Collaboration with safety, reliability, operations, and other cross-functional partners will be essential to integrate the battery into the final system. Your role will also include performing Design for Manufacturability (DFM) and Design for Assembly (DFA) reviews with suppliers, creating statistical tolerance, functional dimensioning, and geometric tolerancing analyses. You will conduct rigorous failure, root cause, and corrective action analyses, and communicate with cell/pack vendors for component and sub-assembly builds. Supporting final assembly activities at supplier sites to ensure proper integration of the battery into the final system will be part of your duties, as well as assisting the sourcing team with cost analysis, supplier audits, and market analysis. **Required Skills:** Battery Product Design Engineer Responsibilities: 1.
