About the Role
Lead end-to-end design execution for silicon spin qubit quantum processor units (QPUs) and test vehicles, from concept through tapeout. This role blends quantum physics and semiconductor engineering, involving new device concepts and building industry-standard infrastructure for manufacturability. It is a hybrid hands-on execution and team leadership position.
Responsibilities
- Translate qubit architecture requirements into manufacturable physical designs, including gate layouts, bias networks, and multi-qubit interconnects.
- Define connectivity/schematic capture and generate netlists for circuit simulation and LVS verification.
- Own tapeouts, including readiness reviews, verification, and risk management.
- Execute critical design work in layout or simulation and review/integrate the other domain.
- Collaborate with experimentalists and the device modeling team to refine designs and device models.
- Define design workflows, standards, toolchains, and guide PDK and DFT development.
- Lead and mentor the QPU Design team.
Requirements
- PhD or equivalent experience in EE, physics, or a related field.
- 8+ years in experimental hardware within research-adjacent or industry environments.
- Led hardware from concept through tapeout with personal accountability.
- Deep expertise in one domain (layout or simulation) with fluency in the other.
- Layout-first: custom physical design using Cadence Virtuoso or similar, hands-on DRC/LVS/extraction, owned tapeouts, worked with sim teams, ran basic TCAD/EM, debugged layout via sim.
- Simulation-first: EM/electrostatic/circuit modeling using tools like Ansys (HFSS/Q3D), Keysight ADS, Cadence Spectre, Synopsys Sentaurus, or equivalent, validated models against measured data, iterated on layouts, understood best practices and DRC constraints, constructively critiqued layout decisions.
- Understanding of semiconductor device physics.
- Built processes, mentored engineers, and integrated across physics/sim/layout.
