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.

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.

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.

Working conditions

• This position is onsite
• May require quarterly off-site meetings or travel
• Regular use of a computer and other office equipment is necessary
• Interaction with team members and external contacts is a regular part of the job
• May require occasional overtime and flexibility in work hours to accommodate the executive’s needs

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 technology and cloud platforms
• Collaborative work environment with cross-functional teams
• Lumilens is an equal opportunity employer. All qualified applicants will receive consideration without regard to race, color, religion, gender, identity, orientation, veteran status, disability, or any other legally protected status.
