Optical Manufacturing Product Engineer

ABOUT LUMILENS

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.

POSITION OVERVIEW

We are seeking an experienced Optical Transceiver Product Engineer to play a critical role in bringing our next generation optical transceiver products from development into high volume manufacturing. In this role, you will own manufacturing readiness and product execution across the product lifecycle, working closely with contract manufacturers, suppliers, and cross functional teams in design, process engineering, quality, and operations. You will help drive the successful launch and scale up of advanced transceiver platforms, with a strong focus on product quality, yield, reliability, and cost.

This is a high impact opportunity for someone with deep expertise in the optical transceiver industry, particularly with 800G and 1.6T products, who thrives in a fast moving environment and wants to help shape the future of optical connectivity.
