**Summary:** The EP Test and Validation team is looking for an Optical Metrology Engineer to verify/validate optical design of eyeglass lenses integrated into eyepieces for smart/AR glasses. This work involves understanding of performance requirements and driving alignment of test requirements with engineering design teams, establishing design verification and manufacturing test strategy for proof-of-concept studies or engineering builds, defining test methods for low-volume lab measurement and high-volume mass production, and delivering performance verification and validation report. **Required Skills:** Optical Metrology Engineer Responsibilities: 1. Work with engineering teams to understand what matters in the product from a performance point of view 2. Take input and convert into parameters that can be objectively measured using off the shelf or custom instruments 3. Define test methods and place instruments to test eyeglass lenses in lab and factory for NPI builds 4. Create and own test plans for low-volume proof-of-concept studies in lab and high-volume mass production 5. Perform measurement and analysis on eyeglass lenses integrated into eyepiece of smart or AR devices 6. Present conclusive results and assess visual/optical performance given design goals and product requirements 7. Provide actionable recommendations and relevant failure analysis to debug or root-cause issues **Minimum Qualifications:** Minimum Qualifications: 8. BS or MS in Optical Engineering or Vision Science 9. 5+ years of industrial experience in optical metrology or engineering 10. Experience in optical performance characterization of eyeglass/photographic lens 11. Familiarity with lens meter/mapper, spectrophotometer, interferometer, surface profiler and wavefront sensor 12. Hands-on experience troubleshooting of optical systems failure analysis 13. Self-motivated, detail-oriented, and self-directed, with little supervision necessary 14. Experience in measurement system analysis and statistical process control 15. Communication and presentation skills **Preferred Qualifications:** Preferred Qualifications: 16. Experience in shipping high-volume product in consumer electronics 17. Experience in one or more optical design tools such as Zemax, Code V, LightTools, FRED, or ASAP 18. Experience with typical image processing algorithms using Matlab or Python **Public Compensation:** $139,000/year to $200,000/year + bonus + equity + benefits **Industry:** Internet **Equal Opportunity:** Meta is proud to be an Equal Employment Opportunity and Affirmative Action employer.
