Product Quality & Reliability Engineer

📋 Job Overview

We are seeking a Product Quality & Test Reliability Engineer to join our rapidly growing team. This isn't just another role. This is a unique opportunity to own the technical vision for our products, work with a world-class multi-disciplinary team, and make a tangible impact from the ground up. The successful candidate will work closely with contract manufacturers, suppliers, and internal cross-functional development teams to meet product objectives and instill a culture of quality and continuous improvement.

🏢 About Lumilens

At Lumilens we are building the critical photonics infrastructure that powers tomorrow’s AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing - faster, cooler, and massively more efficient.

🎯 The Role

This isn’t incremental innovation, it’s a ground-floor opportunity to rethink the optical layer from the silicon up. You’ll work alongside a team of world-class engineers solving some of the hardest challenges in scaling optical systems. Every line of code, every design decision, every breakthrough you help deliver will shape the infrastructure of tomorrow.

✅ Key Responsibilities

• Drive reliability execution for photonic components including Silicon Photonics ICs, lasers (DFB, CW lasers etc), and Optoelectronic SiPs used in high-speed optical networks.
• Partner with R&D and design engineering to provide early reliability input during the product development lifecycle.
• Define and execute qualification plans aligned with Telcordia/GR-468, JEDEC, and other relevant standards for telecom and datacom products.
• Conduct accelerated life testing (ALT), failure analysis, degradation modeling, and root cause investigations to guide design and process improvement.
• Collaborate closely with cross-functional teams including Photonics Design, Packaging, Manufacturing, Quality Engineering, Product Marketing and Supply Chain to ensure robust product development and transfer to production.
• Lead supplier qualification activities and implement supplier quality metrics for critical photonics components.
• Support supplier audits, assess factory capability, process controls, reliability models, and product roadmaps.
• Support the infrastructure to perform incoming component validation.
• Develop and maintain Design for Reliability (DfR) methodologies, including predictive modeling and statistical analysis.
• Prepare, present and document technical reviews, reliability reports, and risk assessments for internal and customer-facing engagements.

📌 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 technologies, and optical transceivers.
• 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), and 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.

⭐ Desirable Experience

• 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
• Collaborative work environment with cross-functional teams solving complex engineering challenges
