Job Description & How to Apply Below
Hardware+ 1 more Apply nowMeta Reality Labs is seeking a Battery Product Design Engineer to lead the end-to-end design and integration of battery systems for next-generation virtual and augmented reality devices, including headsets, wearables, and smart glasses. In this role, you will own the technical strategy and execution for battery cell selection, pack architecture, and safety system design across Meta's Reality Labs hardware portfolio, driving innovations in energy density, thermal management, and mechanical integration within the highly constrained form factors of consumer wearable devices.
---## Battery Product Design Engineer Responsibilities
* Define and own the battery pack architecture and system-level design strategy for VR/AR headsets and wearable devices, including cell selection, pack topology, protection circuitry, and mechanical integration
* Lead cell evaluation and qualification programs — characterize electrochemical performance, abuse tolerance, cycle life, and calendar aging across candidate cell chemistries and form factors
* Drive cross-functional execution with mechanical, electrical, thermal, firmware, and safety engineering teams to integrate battery systems into wearable product designs from concept through mass production
* Establish and own battery system requirements — energy capacity, power delivery, thermal limits, swelling tolerances, and safety thresholds — and ensure traceability through design validation
* Lead design failure mode and effects analysis for battery packs and protection systems, and own resolution of safety-critical design risks across the product development cycle
* Collaborate with contract manufacturers and cell suppliers to define manufacturing process requirements, incoming quality controls, and production test specifications for battery pack assembly
* Develop and execute battery validation plans including electrical characterization, mechanical abuse, thermal runaway propagation, and regulatory compliance testing for consumer electronics standards
