About the role
Lumilens is revolutionizing AI compute infrastructure with next-generation photonic interconnects. Our solutions—leveraging co-packaged optics (CPO), near-packaged optics (NPO), high-density silicon photonics, and advanced heterogeneous integration—enable massive scale-out and scale-up architectures for the world's leading AI providers.
What they're looking for
- Bachelor's or Master's degree in Electrical Engineering, Physics, or related field (PhD preferred)
- 10+ years of relevant experience in high-speed SI/PI, with strong emphasis on board-level, package-level, and silicon-level design/validation
- Deep expertise in very high-speed SerDes (≥56G, preferably 100G/200G PAM4), including channel modeling, equalization (FFE/DFE/CTLE), jitter/crosstalk analysis, eye diagrams, BER, and compliance/margining
- Extensive hands-on experience with leading SI/PI/EM tools (e.g., Ansys HFSS 3D/Layout, SIwave, Clarity, CST, Keysight ADS Momentum/Sigrity, HSPICE, HyperLynx)
- Proven proficiency in time-domain transient simulations (HSPICE, ADS, MATLAB/Simulink) and scripting/automation (Python, TCL, MATLAB) for simulation flows, data analysis, and reporting
- Hands-on experience with 2.5D/3D packaging technologies (silicon/organic interposers, chiplet integration, HBM stacking) and high-frequency transmission line routing in silicon/photonic contexts
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. 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.
