- 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. At Lumilens, we’re developing high-speed photonics products purpose-built to power the future of AI infrastructure and high-performance computing.
- 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.
- 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 & 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.
- 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.
- What We Offer
- 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
