What are the responsibilities and job description for the Product Line Manager position at Lumilens?
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
Lumilens is seeking a Product Line Manager to support strategy and execution across high-speed optical interconnect solutions. In this individual contributor role, you will partner closely with product management, program management, application engineering, and commercial teams to help define product priorities, support customer engagement, and drive execution against business goals. You will contribute to product lifecycle management, market analysis, and cross-functional coordination across high-speed optical interconnect solutions, with particular emphasis on pluggable optics and next-generation 800G and 1.6T transceiver platforms for cloud, AI, and optical networking customers.
