Display Test Engineer, Optical Metrology

Meta Meta · Big Tech · Regensburg, Germany

Staff Display Test Engineer to lead test development and equipment bring-up for advanced microdisplay technologies, from early development through high-volume manufacturing. Owns cleanroom test toolset, defines test programs and methodologies, sets measurement and correlation standards, drives root-cause analysis, manages vendor relationships, and leads test system transfer. Requires experience in semiconductor test, display test engineering, or optical metrology.

What you'd actually do

  1. Lead the bring-up, qualification, and lifecycle ownership of dozens of cleanroom test tools for wafer-level and module-level microdisplay characterization and production
  2. Define the optical and electrical test strategy for display characterization and production test, translating display quality requirements into measurable specifications and acceptance criteria
  3. Architect, write, and optimize test programs and automated test frameworks for high-throughput display measurement in cleanroom environments
  4. 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
  5. 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

Skills

Required

  • 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

Nice to have

  • 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)
