Responsibilities

Cryo‑CMOS Control Chip Architecture & Design: Lead the design of ultra‑low‑temperature CMOS control ASICs for cryogenic quantum systems

Collaborate with device, packaging, and quantum hardware teams to co‑optimize performance, noise, thermal load, and reliability

Own the architecture and implementation of room‑temperature instrumentation logic, including data‑acquisition pipelines, control sequencing, and high‑speed digital interfaces

Lead the migration of FPGA‑based prototypes into production‑grade ASIC implementations, including register-transfer level (RTL) refinement, timing closure, and power/performance optimization

Establish robust verification, emulation, and bring‑up workflows to ensure seamless transition from FPGA to custom silicon

Develop and maintain layout methodologies and physical‑design flows that support advanced cryo‑CMOS and mixed‑signal ASICs

Work closely with foundry partners to influence and refine PDK features, device models, and design‑rule evolution
