About the Job

Requirements

  • Strong understanding of semiconductor device physics, preferably semiconductor lasers, high-power laser diodes, or related optoelectronic devices.
  • Experience with UHP/high-power laser chip fabrication or relevant experience in photonics, optoelectronics, III-V semiconductors, or other semiconductor manufacturing environments.
  • Strong experience in yield engineering and data mining, including translating manufacturing and test data into actionable yield-improvement opportunities.
  • Solid understanding of statistical analysis and engineering methods such as statistical process control, design of experiments, and correlation/regression analysis.
  • Experience investigating quality, reliability, manufacturing, or customer-return issues and driving problems from initial containment through verified root cause and corrective action.
  • Candidates must have a degree in Electrical Engineering, Physics, Chemistry, Materials Science, or a closely related technical discipline, and meet one of these experience combinations: Ph.D. with 5+ years of relevant industry experience; M.S. with 8+ years; or B.S. with 10+ years.
  • Relevant experience should preferably include semiconductor lasers, photonics, optoelectronics, compound-semiconductor fabrication, or another semiconductor manufacturing environment.

Responsibilities

  • Drive yield improvement for semiconductor laser wafer and chip fabrication through systematic analysis of manufacturing, process, test, and device-performance data.
  • Analyze large datasets to identify yield limiters, process excursions, and systematic failure signatures.
  • Lead root-cause investigations for manufacturing and customer quality issues using structured problem-solving methodologies and data-driven analysis.
  • Work with process engineering and research and development teams to design and execute design-of-experiments for process-improvement experiments.
  • Establish and monitor yield, process, and quality metrics to identify abnormal trends and excursions.
  • Lead or contribute to 8D, corrective and preventive action, failure mode and effects analysis, statistical process control, and other quality-improvement activities.
  • Partner cross-functionally with device engineering, wafer fabrication, chip processing, manufacturing, test, reliability, quality, and supplier teams.
  • Communicate technical findings and recommendations to manufacturing, engineering teams, and management.

Desired Qualifications

  • Experience with analytical/data-mining tools such as JMP, Python, SQL, or equivalent.
  • Direct experience with high-power or ultra-high-power semiconductor laser diodes.
  • Experience correlating wafer fabrication parameters with optical/electrical device performance and reliability.
  • Knowledge of III-V materials and devices, particularly InP-based laser technologies.
  • Experience with wafer-level or chip-level test data analysis.
  • Demonstrated success delivering measurable improvements in yield, process capability, product quality, or reliability.
  • Strong understanding of failure mechanisms and failure-analysis techniques relevant to semiconductor laser devices.
  • Experience working in a high-volume or rapidly scaling semiconductor/photonics manufacturing environment.
