**Summary:** The RL (Reality Lab) team at Meta is helping more people around the world come together and connect through world-class hardware and software. As part of the RL Devices team, we are builders who break down barriers to what is possible. Together we design and build manufacturing processes that transform technology into products.The Subject Matter Expert engineer (SME) Team has the responsibility for evaluating technologies and identifying supply chain solutions that allow Meta to deliver products to market at scale. We are seeking a Subject Matter Expert engineer (SME) for an individual willing to work independently to accomplish bold things. Specific hardware development and operations knowledge are required. As Subject Matter Expert engineer (SME) in the Devices organization, you will be responsible for both technically proficient work with the engineering design and Operations teams, for critical parts of optic components process development and manufacturing at vendors. You will collaborate across multiple projects with display, optic product designers to enable novel AR/VR experiences. You will be the interface between the Tech Ops Engineering, Supply Chain, and Manufacturing teams to implement and execute comprehensive process and technical solutions for our products. **Required Skills:** Subject Matter Expert Engineer Responsibilities: 1. Drive manufacturing process innovation in optic component solutions for AR/VR products. 2. Work with Hardware Engineering, Sourcing, Quality and Tech Ops Team to identify, audit and select the best suppliers’ partner (SPOR) to manufacture our products 3. Responsible for cover glass manufacturing, CMF processes (PVD, CVD, sputtering, painting), cover window manufacturing, film/lens lamination, die cut, laser cutting, adhesion (i.e. Optical Crystal Adhesion), cover window coating process development (i.e. AR coating, IR ink development, optical coating) 4. Process DFM, process bring up and qualifications 5. Develop MP intend equipment, process and materials. 6. Set CTQ criteria to validate key processes. 7. Run statistical analysis from data collected through trials & investigations. 8.
