Power Integrity Engineer

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.

We are seeking a skilled Power Integrity (PI) Engineer to optimize power distribution networks for OSFP transceiver designs. You will collaborate with cross‑functional teams to ensure robust, low‑noise power delivery for high‑speed silicon photonics, DSPs, and retimers, minimizing PDN impedance and electromagnetic interference in dense 800G+ modules.

• Perform PI simulations using tools like Ansys SIwave, Keysight ADS, or Cadence Sigrity to model and optimize PDN for OSFP modules, targeting
