Product Quality & Reliability Engineer

The role

The Product Quality & Reliability Engineer will drive reliability execution for photonic components. This role involves partnering with R&D and design engineering to provide reliability input and executing qualification plans.

What you will do

• Drive reliability execution for photonic components including Silicon Photonics ICs, lasers, and Optoelectronic SiPs.
• Partner with R&D and design engineering to provide early reliability input.
• Define and execute qualification plans aligned with Telcordia/GR-468, JEDEC, and other standards.
• Conduct accelerated life testing, failure analysis, degradation modeling, and root cause investigations.
• Collaborate with cross-functional teams to ensure robust product development and transfer to production.
• Lead supplier qualification activities and implement supplier quality metrics.
• Support supplier audits and assess factory capability, process controls, and reliability models.
• Support the infrastructure to perform incoming component validation.
• Develop and maintain Design for Reliability methodologies.
• Prepare and document technical reviews, reliability reports, and risk assessments.

Required qualifications

• M.S. in Electrical Engineering, Photonics, Physics, Materials Science, or related field, or equivalent experience in photonics reliability engineering with direct exposure to Silicon Photonics, laser
• Strong background in photonics device physics, photonics packaging, and failure mechanisms.
• Demonstrated success supporting NPI programs and product qualification from concept through volume production.
• In-depth knowledge of relevant standards (GR-468, Telcordia, JEDEC, MIL-STD).
• Proficiency with reliability modeling, statistical analysis (e.g., Weibull, Arrhenius), and tools such as JMP, Minitab, or similar.
• Hands-on experience with reliability test systems (e.g., HTOL, HAST, T/H, TC).
• Hands-on experience with FA tools (e.g., SEM, FIB, X-ray, spectroscopy).
• Effective communicator with the ability to influence cross-functional and supplier teams.
• Experience in a fast-paced, high-tech environment serving telecom/datacom markets.

Nice to have

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

Benefits

• Competitive salary commensurate with experience
• Comprehensive benefits package including health insurance
• Professional development opportunities and certification support
• Access to cutting-edge photonics technology and advanced packaging environments
