Senior Photonic Layout Engineer Berkeley, CA $150k–approximately $230k *Open to PHD candidates - Senior. We’re working with an early-stage photonic computing company developing an integrated optical-electronic platform for AI workloads. The approach uses light to address the power, data-movement and compute-density challenges of conventional electronic accelerators. The work spans photonic compute, electronic ICs, packaging, memory and system architecture, with a focus on turning research silicon into a commercial computing platform. They’re hiring a Senior Photonic Layout Engineer to own the photonic layout and tape-out flow, connecting PIC development with the electronic IC work already underway. The role • Own the photonic layout flow from design implementation and routing through verification, sign-off and tape-out release. • Establish a Cadence Photonics workflow for GlobalFoundries’ 45 nm process, compatible with the electronic IC design flow. • Personally implement photonic and electronic layout and routing within Cadence, resolving interfaces between the two domains. • Own netlisting, DRC/LVS and foundry/PDK integration, ensuring designs meet manufacturing requirements. Your experience • Direct PIC design experience, with substantial personal ownership of layout implementation, routing and verification. • Strong hands-on Cadence experience, including practical work connecting photonic and electronic design flows. • Experience taking commercial photonic designs toward tape-out, with clear accountability for your own implementation and sign-off work. • Practical ownership of foundry PDKs, design rules, netlisting and DRC/LVS. • A strong understanding of silicon-photonics device physics, supported by device or circuit design and simulation experience. • The ability to work across PIC, EIC, packaging and lab validation, understanding how layout decisions affect the integrated system. • Comfort with hands-on execution, broad responsibility and establishing a design flow within a small team. Why join? You’ll own a foundational part of a photonic computing platform while major design and integration decisions are still open. The work connects photonic devices with electronic ICs, packaging and measured hardware performance. You’ll work directly with a technically deep founding team and help build the workflow that turns individual designs into a complete, manufacturable system. This is an opportunity for someone who wants to take responsibility for chip-level implementation and help move photonic computing from research silicon toward a commercial product. Interested?
