Cryo-CMOS Analogue Modeling Lead

Oxford Ionics; Oxford; Hybrid; GBP 90,000 - 130,000; Full time

Job summary

Oxford Ionics in Oxford, UK, seeks an Analogue Designer for CMOS modelling to own full-chip mixed-signal modelling in Cryo-CMOS development for trapped-ion quantum processors.

You will implement models in Verilog-A/AMS, SystemVerilog, and real-number representations, aligning with design releases and test silicon data. The role requires robust mathematical derivations and collaboration across a fast-moving technical team.

Qualifications

• 10+ years of deep analogue and mixed-signal design and modelling experience.
• Experience with expert Verilog-A and Verilog-AMS and strong real-number modelling.
• Ability to derive models from equations and implement end-to-end.

Responsibilities

• Own the full-chip modelling strategy including architecture, abstraction levels, accuracy targets and sign-off criteria.
• Develop Verilog-A/Verilog-AMS models of analogue blocks and assemble into a simulatable full chip.
• Build real-number models so the full chip runs in digital verification and regression at speed.
• Derive models from mathematics and translate into robust Verilog-A with tolerances.
• Define and run model-versus-schematic correlation and feed back measured silicon behaviour.
• Stand up mixed-signal co-simulation and regression; mentor engineers on modelling craft.
