Staff/Sr Staff Electro-Optic Link Codesign Engineer

We are seeking a Sr. Staff Engineer, Photonic Link Co-Design to join our Laser Systems Architecture & Engineering team. This is one of the most technically demanding roles at Lightmatter: you will own the end-to-end simulation, co-design, and laboratory verification of photonic-electronic links in Passage™ — from photonic device modeling through to full transceiver channel characterization in silicon.

You will build and maintain the high-fidelity simulation infrastructure that links optical device performance to system-level BER and link margin, drive co-design between photonic and analog circuit teams, and close the loop between simulation and lab measurement on every tape-out. This role sits at the center of how Lightmatter ensures Passage links meet performance at every process corner — and is the technical anchor for photonic-electronic integration quality.
