Yield & Quality Engineer – UHP and CW Laser / Photonics Semiconductor

About the role

We are seeking an experienced Yield & Quality Engineer with a strong technical background in ultra-high-power (UHP) semiconductor laser chip fabrication or closely related photonics/compound-semiconductor technology.

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 R&D teams to design and execute DOE for process improvement experiments.
• Establish and monitor yield, process, and quality metrics to identify abnormal trends and excursions.
• Lead or contribute to 8D, CAPA, FMEA, SPC, 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 clearly to manufacturing, engineering teams, and management.

Requirements

• Strong understanding of semiconductor device physics, preferably semiconductor lasers, high-power laser diodes, or related optoelectronics devices.
• Experience with UHP/high-power laser chip fabrication is strongly preferred; relevant experience in photonics, optoelectronics, III-V semiconductors, or other semiconductor manufacturing environments will also be considered.
• Strong experience in yield engineering and data mining, with demonstrated ability to translate manufacturing and test data into actionable yield-improvement opportunities.
• Solid understanding of statistical analysis and engineering methods such as SPC, DOE, 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.
• Experience with analytical/data-mining tools such as JMP, Python, SQL, or equivalent is highly desirable.

Qualifications

• Candidates should have a degree in Electrical Engineering, Physics, Chemistry, Materials Science, or a closely related technical discipline, with one of the following combinations:
• Ph.D. with 5+ years of relevant industry experience;
• M.S. with 8+ years of relevant industry experience;
• B.S. with 10+ years of relevant industry experience.

Preferred Qualifications

• 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.
• Strong technical communication and structured problem-solving skills.

Pay

The salary range for this position is $89,650 – $166,000USD. Final compensation will be determined based on factors such as experience, skills, and qualifications.
