Summary:

As a Battery System Engineer at Meta, you will take ownership of the Battery pack electrical designs and their integrations to power the state-of-the-art devices developed by Reality Labs. You will work closely with our product engineering teams to define battery requirements, aiming to find the best options for product volume, weight, and run time. You will provide build support during New Product Introduction activities to ensure that manufacturing processes align with design intent. Collaboration with safety, reliability, operations, software and other cross-functional partners will be essential to integrate the battery into the final system and meet system level performance metrics. 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.
