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. 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.
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 You'll Own
The full DV strategy: verification plan, coverage model (functional + code), UVM architecture, and signoff criteria from block to full-chip.
Stand up regression/CI infrastructure and nightly runs before design hands over first RTL.
Verification of the in-house engines against an algorithmic golden model, with programmable error injection and error-pattern coverage.
Hardware-assisted verification: bring up and own the emulation / FPGA-prototyping methodology.
UCIe VIP and compliance, link-training, loopback, lane-repair scenarios, bit-exact transparency and more.
Performance and throughput verification.
UVM register verification, firmware co-simulation, and boot flows on the MCU subsystem.
Mixed-signal co-simulation — verifying the digital front end against behavioral models of analog/mixed-signal blocks.
Gate-level and low-power (UPF) verification as part of signoff.
Lead and grow the DV team (across FEC, UCIe, MCU, datapath, and full-chip).
Required
10+ years ASIC/SoC verification, with team leadership on at least one complex SoC from plan to tapeout.
Proven leadership verifying large, complex digital SoCs / subsystems, including interconnect fabric and full-chip closure.
Deep UVM/SystemVerilog; coverage-driven verification; constrained-random methodology.
Hands-on with hardware-assisted verification — emulation (e.g., Palladium/Veloce) and/or FPGA prototyping (e.g., HAPS/Protium).
Comfortable with mixed-signal verification (Verilog-AMS or SV real models).
Regression/CI at scale (grid, triage automation), and rigorous coverage closure.
Preferred
High-speed SerDes, PAM4, or FEC/coding (Reed-Solomon) verification experience.
UCIe, PCIe/CXL, Ethernet, UALink or comparable die-to-die / link-layer VIP and compliance experience.
NIC Cards, Ethernet/IB Switches, Cache-coherency verification (multi-core / coherent fabric).
Low-power/UPF and gate-level simulation methodology.
Performance-verification methodology.
Formal verification for control/interlock logic; portable-stimulus.
