Battery Engineer Jobs in Seattle, WA (NOW HIRING)

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.
Responsibilities
Mechanical engineering and packaging for lightweight, swappable battery technology. Reliability, safety, and weight are critical requirements
• Planning and executing on performance, validation, endurance, and life cycle testing
• Troubleshooting root-cause of mechanical failures, implementing improved designs, testing effectiveness of change
• Lead CM's and Scaling partners paving the way for high volume production when projects mature
• Collaborate closely with reliability team to implement best practices for high-reliability mechanical and electrical design
• Build subsystem test fixtures, design tests, create test plans, perform tests, measure and analyze data, and refine design assumptions
• Collaboration: Work closely with a cross-functional team of engineers (EE, SW, Firmware) to deliver complete technical solutions
• Design of battery docking and interface components
• Design of other humanoid robot systems as needed
Minimum Qualifications
• 8+ years experience in Mechanical Design Engineering
• BS degree or equivalent experience in Mechanical Engineering or a related field
