Job description

Summary:

At Meta, we’re building the future of human connection and the technology that enables it. This means continuously inventing and developing technologies for the next generation of experiences. To continue our efforts in the path to AGI, and as we move closer to a future with intelligent robots and advanced AI models, we're hiring talent across a broad range of disciplines from robotics hardware to system software, machine perception, and artificial intelligence. These crucial projects and initiatives taken on by this team have never been done before, so you have a rare opportunity to help us create new ways people connect around the world. The Meta Robotics Hardware team is seeking a Mechanical Design Engineer with an emphasis on lightweight battery pack design, thermal management, performance testing, and bringing battery designs from concept to product release. This role will be part of a ME team responsible for consumer humanoid development at Meta. Candidates should be experienced working in a high ambiguity, ever evolving environment where full system requirements are seldom known. This team is dedicated to building hardware that enables learning through data collection and testing.
