About the role
You own verification end to end for a first-of-its-kind chiplet. As a founding hire you define the methodology before there's RTL to verify — this role is on the critical path, and getting the coverage strategy and regression infrastructure right early is the single biggest schedule lever we have.
What they're looking for
- 10+ years digital design / micro-architecture, with lead ownership of a high-throughput datapath or SerDes-adjacent SoC
- Experience designing the datapath of a network switch/NIC card or memory controller at a major XPU / fabric vendor (or a comparable high-throughput, high-reliability datapath)
- Solid understanding of scale-up vs. scale-out interconnect architectures and their bandwidth/latency trade-offs
- Strong SystemVerilog RTL and timing-aware micro-architecture at multi-hundred-Gbps aggregate rates, CDC discipline
- Working command of UCIe/PCIe/CXL datapath concepts and high-speed lane alignment/deskew
- Proven ownership of front-end design methodology — lint/CDC/RDC signoff, clocking/reset architecture, and design-for-test and physical-closure collaboration
More about this role
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. The market is moving fast, and we’re moving faster. 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.
