Senior or Principal Process Design Kit (PDK) Engineer

Own the model-to-measurement characterization loop for cryogenic process primitives, including test definition, measurement planning, data analysis, parameter extraction, and model update workflows. Develop, maintain, and refine cryogenic PDK requirements for superconducting circuit technologies, with emphasis on accurate low-temperature device models, parameter extraction, and design-rule coverage. Partner with external foundries and internal teams to extend foundry PDKs from room-temperature or nominal process assumptions to cryogenic operating regimes relevant to quantum hardware. Plan, design, and analyze cryogenic characterization test chips for key primitives. Partner with foundry, device, packaging, and quantum-hardware design teams to connect fabrication process capability, measured cryogenic performance, and scalable circuit-design requirements. Establish robust characterization infrastructure, including design-of-experiments methods, test structures, data pipelines, statistical summaries, and documentation that enable repeatable PDK updates. Use industry-standard electronic-design-automation, layout, and physical-verification toolsets to support superconducting circuit design, test-chip development, and PDK validation.
