At Lumilens we are building the critical photonics infrastructure that powers tomorrowâs 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.
Weâre a well-funded startup backed by Mayfield and led by veterans whoâve built and scaled some of the most transformative technologies in the industry. At Lumilens, weâre developing high-speed photonics products purpose-built to power the future of AI infrastructure and high-performance computing.
This isnât incremental innovation, itâs a ground-floor opportunity to rethink the optical layer from the silicon up. Youâll 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. Weâre just getting started.
As Director of Operations, Silicon Photonics, you will lead the strategy and execution of manufacturing operations across our photonics process technologies, including silicon photonics integration, advanced packaging, and optical module assembly.
You will be responsible for scaling manufacturing capability, driving cost and yield breakthroughs, and aligning internal teams and external partners (foundries, OSATs, and equipment suppliers) to deliver world-class performance. This role sits at the intersection of engineering, supply chain, and production, and is critical to transitioning Lumilens from development to high-volume manufacturing.
