Lead Systems Applications Engineer

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.

We are seeking a highly skilled and motivated System Application Engineer to join our dynamic team. The ideal candidate will possess extensive experience with AI networking switch architecture and configurations, along with a deep understanding of optical transceivers on switches. This role involves supporting customers with 800G and 1.6T optical transceivers on 51.2T and beyond switches.
