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.
We’re a well-funded startup backed by Mayfield and led by veterans who’ve built and scaled some of the most transformative technologies in the industry. 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 optics, systems, and scale. Every line of code, every design decision, every breakthrough you help deliver will shape the infrastructure of tomorrow.
If you're looking for mission, momentum, and the chance to make an outsized impact jump on the rocket ship. We’re just getting started.
POSITION OVERVIEW
We are seeking a Product Quality 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.
What You'll Do:
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.
Key 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.
Preferred Skills:
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.
Why Join Us?
This is more than a job. It's a chance to get in on the ground floor of a well-funded company set to disrupt a multi-billion dollar market. You will have the autonomy to make a massive impact, the resources to execute your vision, and a significant stake in the company you help build.
