Product Quality & Reliability Engineer

Job Title

Product Quality & Reliability Engineer

Role Summary

Owner of product reliability and quality engineering for high-speed photonics products. Work with R&D, design, manufacturing, suppliers and contract manufacturers to define and execute qualification plans, drive failure analysis and ensure successful transfer to production.

Work contributes to foundational photonics infrastructure for AI and high-performance computing.

Experience Level

Mid-level. The posting does not specify years, but the role expects hands-on experience in photonics reliability and product qualification.

Responsibilities

Key responsibilities include:

• Drive reliability execution for photonic components (Silicon Photonics ICs, DFB/CW lasers, optoelectronic SiPs) used in high-speed optical networks.
• Provide early reliability input during product development and support NPI programs through volume production.
• Define and execute qualification and acceptance plans aligned with Telcordia/GR-468, JEDEC, and applicable standards.
• Plan and perform accelerated life testing (ALT), failure analysis, degradation modeling, and root cause investigations to guide design and process improvements.
• Lead supplier qualification, implement supplier quality metrics, and support supplier audits and factory capability assessments.
• Support incoming component validation and develop/maintain Design for Reliability (DfR) methodologies.
• Use predictive modeling and statistical analysis to assess reliability and risk.
• Prepare and present technical reviews, reliability reports, and customer-facing risk assessments.

Requirements

Must-have:

• Proven experience executing reliability programs for photonic components and optical transceivers.
• Strong background in photonics device physics, packaging, and failure mechanisms.
• Demonstrated success supporting NPI and product qualification from concept through volume production.
• Knowledge of GR-468, Telcordia, JEDEC, and relevant military/industry standards.
• Proficiency in reliability modeling and statistical analysis (e.g., Weibull, Arrhenius) and tools such as JMP or Minitab.
• Hands-on experience with reliability test systems (HTOL, HAST, thermal/humidity, temperature cycling) and failure analysis tools (SEM, FIB, X‑ray, spectroscopy).
• Experience leading supplier qualification, audits, and defining supplier quality metrics.
• Effective written and verbal communication with ability to influence cross-functional and supplier teams.
• Experience in fast-paced, high-tech environments serving telecom/datacom markets.

Nice-to-have:

• Experience in integrated photonics packaging and optical-electrical co-design.
• Familiarity with wafer-level reliability testing and optical wafer probing.
• Prior engagements with Tier-1 datacenter customers or hyperscalers.

Education Requirements

M.S. in Electrical Engineering, Photonics, Physics, Materials Science, or a related technical field is listed as preferred; equivalent practical experience in photonics reliability engineering is explicitly accepted.
