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 decision you make will directly influence how we build, source, and deliver 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 an Equipment and Fixture Buyer to join our rapidly growing team. This role is critical in sourcing and procuring production equipment, fixtures, tooling, and related materials that support prototype, NPI, and manufacturing scale-up across our photonics and advanced hardware operations.

You will be responsible for managing end-to-end purchasing activities for capital equipment, manufacturing fixtures, tooling, and related support items, ensuring suppliers, pricing, and delivery plans align with engineering, operations, and manufacturing requirements. The ideal candidate will partner closely with hardware, mechanical, manufacturing, quality, and supply chain teams to drive sourcing strategy, supplier selection, RFQs, purchase execution, commercial negotiations, lead-time management, and risk mitigation. This is a highly visible role with direct impact on build readiness, production continuity, cost, and supply resiliency.
