We are seeking a Product Quality & Test Reliability Engineer to own the technical vision for Lumilens products, working with contract manufacturers, suppliers, and cross-functional teams to instill a culture of quality and continuous improvement.
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.
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.
