Display Test Engineer, Optical Metrology

Meta Reality Labs is seeking a Staff Display Test Engineer to lead test development and equipment bring-up for advanced microdisplay technologies, from early development through high-volume manufacturing. You'll own the cleanroom test toolset, lead the bring-up of dozens of characterization and production test tools, and define the test programs and methodologies that ensure display quality across the product lifecycle. You'll set the measurement and correlation standards -- the "ruler" by which product performance is judged -- and drive their adoption across internal teams and global manufacturing partners. You'll operate with broad autonomy, influence test strategy across programs and sites, partner with vendors to debug and improve equipment, and mentor engineers as we scale test infrastructure to meet ramp-up timelines.
Display Test Engineer, Optical Metrology Responsibilities
Lead the bring-up, qualification, and lifecycle ownership of dozens of cleanroom test tools for wafer-level and module-level microdisplay characterization and production
Define the optical and electrical test strategy for display characterization and production test, translating display quality requirements into measurable specifications and acceptance criteria
Architect, write, and optimize test programs and automated test frameworks for high-throughput display measurement in cleanroom environments
Establish measurement standards -- calibration, correlation methodology, and measurement system analysis (accuracy, Gauge R&R, stability) -- so results are robust, repeatable, and traceable across sites and vendors
Drive root-cause analysis of test program issues, equipment failures, and display defects by correlating test data with process and design parameters, and implement durable solutions
Own vendor and manufacturing-partner relationships: hold partners accountable to performance specs, keep them aligned to priorities, and drive long-term equipment and capability improvements
Lead the transfer of test systems and tester readiness from new-technology introduction through new-product introduction and high-volume manufacturing across multiple factories
Drive cross-functional collaboration with display, process, packaging, and manufacturing engineering teams to integrate test solutions into production workflows
Set technical direction and best practices for the test organization and mentor engineers across the test organization

Minimum Qualifications:

Bachelor's degree in Electrical Engineering, Optics/Photonics, Physics, or a related field
8+ years of experience in semiconductor test, display test engineering, or optical metrology for consumer electronics or imaging systems
Experience independently leading test development and equipment bring-up programs end-to-end
Experience with cleanroom tool ownership: bring-up, qualification, and maintenance
Experience writing and debugging test programs for semiconductor or display test equipment
Experience developing automated test software in Python, MATLAB, or an equivalent programming language or environment
Experience managing vendor relationships and driving equipment improvements
Experience translating device requirements into test specifications across hardware and manufacturing teams

Preferred Qualifications:

Proficiency in an additional language relevant to collaboration with international equipment vendors (e.g., Mandarin Chinese)
Experience with microdisplay / micro LED technologies
Experience qualifying test tools in a cleanroom or fab environment, including high-parallelism / high-throughput testing equipment
Proficiency in scripting in Lua (in addition to Python/MATLAB)
Experience with semiconductor wafer-level test methodologies and equipment
Experience in driving a test strategy across multiple global manufacturing sites/partners
Background in optical measurement instrumentation (spectroradiometers, imaging colorimeters, probe stations)
