Senior Semiconductor Test Engineer

Job Purpose:

The Senior Semiconductor Test Engineer leads the development, optimization, and long-term sustainment of advanced test processes for semiconductor devices, with a strong emphasis on high-power laser diode technologies. This role drives technical strategy, mentors junior engineers, and ensures robust, scalable test solutions that support both high-volume manufacturing and new product introduction.

Key Responsibilities:

• Own and lead test process development for semiconductor devices, including laser diode chips, bars, arrays, and integrated assemblies.
• Serve as the primary technical expert for troubleshooting complex test and yield issues across production lines.
• Perform advanced data analysis to characterize device performance, identify systemic issues, and drive long‑term improvements.
• Lead validation and implementation of design changes, ensuring test readiness, documentation accuracy, and process stability.
• Partner with R&D, Product Development, and Operations to guide new product introduction (NPI) from prototype through full‑scale manufacturing.
• Architect and optimize automated test equipment (ATE), fixtures, and software to improve throughput, accuracy, and repeatability.
• Drive yield improvement and cost‑reduction initiatives, identifying failure modes and recommending design or process enhancements.
• Champion best practices in test methodology, statistical process control (SPC), and data‑driven decision‑making.
• Mentor and support junior engineers and technicians, providing technical guidance and training.
• Ensure compliance with quality, safety, and reliability standards across all test operations.

Skills & Qualifications:

• Bachelor’s or Master’s degree in Electrical Engineering, Physics, Materials Science, or related field.
• Extensive experience in semiconductor device testing, optoelectronics, or laser diode characterization.
• Proven ability to diagnose complex test issues and implement engineering‑level solutions.
• Strong background with automated test systems, data acquisition, and statistical analysis tools.
• Deep understanding of semiconductor device physics and optical/electrical performance metrics.
• Excellent communication skills and demonstrated success working cross‑functionally.

Preferred Skills:

• Experience with high‑power laser diodes, photonics packaging, or reliability testing.
• Proficiency in test automation programming (Python, LabVIEW, MATLAB, C/C++).
• Hands‑on experience with DOE, SPC, FMEA, and other structured problem‑solving methodologies.
• Familiarity with high‑volume manufacturing environments and continuous improvement frameworks.
