Cryogenic CMOS & Quantum Device Modeling Engineer

GlobalFoundries inc.; Springfield (IL); On-site; USD 98,000 - 176,000; Full time

Job summary

GlobalFoundries develops and deploys predictive models for CMOS, superconducting and photonic devices across room temperature and cryogenic regimes. The role translates device physics into simulation-ready compact models for transistors and quantum/photonic elements, enabling cryoCMOS PDKs and cryogenic control/readout designs.

You will integrate models into PDK/EDA workflows, validate against measured data, and collaborate with device, technology, PDK, EDA, and circuit-design teams to deliver

Qualifications

• Bachelor's degree in Electrical Engineering, Microelectronics, Physics, Applied Physics, or related field.
• Minimum 5 years applying semiconductor device physics to device modeling, extraction, characterization, or related work.
• Strong background in semiconductor device physics and MOSFET electrical behavior, including short-channel effects and temperature dependence.
• Experience developing or applying models for superconducting and photonic elements and deploying in circuit/systems simulations.
• Hands-on experience with compact-model parameter extraction and model validation from measured data.
• Experience with SPICE-class circuit simulation and commercial EDA tools (Cadence, Synopsys, Siemens).
• Proficiency in data analysis and automation using Python, MATLAB, or equivalents in Linux/Unix.
• Fluency in English - written and verbal.

Responsibilities

• Develop and calibrate physics-based compact models for CMOS and transistor technologies across room-temperature and cryogenic regimes.
• Develop, calibrate, and validate models for superconducting and photonic elements using measured data and physics-based frameworks.
• Plan and execute parameter-extraction and model-validation workflows from test structures and chips.
• Correlate model behavior with data, device physics, and TCAD results; identify limitations and actions.
• Define device/test-structure requirements to extract and improve models for cryogenic design enablement.
• Integrate and qualify model files within PDK/EDA environments, including regression testing and release readiness.
• Analyze temperature-dependent device behavior, variability, and reliability; translate into design guidance.
• Collaborate with cross-functional teams to establish model requirements and delivery priorities.
• Communicate model assumptions, validation results, and usage recommendations in technical reports.
