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
We are seeking an experienced Die Attach & Wire Bond Process Technician to support semiconductor and photonics assembly processes in both NPI and production environments.
The technician will work closely with Process Engineers, Manufacturing, and Quality teams to support die attach, epoxy dispensing, curing, wire bonding, process setup, equipment operation, troubleshooting, process qualification, and production ramp activities.
