Cryogenic CMOS & Quantum Device Modeling Engineer

GlobalFoundries inc.; New York (NY); On-site; USD 98,000 - 176,000; Full time

Job summary

GlobalFoundries seeks a Device Modeling Engineer with a core background in semiconductor device physics to develop, extract, validate, and deploy predictive models from room temperature to cryogenic temperatures.

This role translates measured behavior into simulation-ready compact models for transistors, superconducting, and photonic elements, enabling cryoCMOS PDKs, quantum control and readout circuits, photonic design enablement, and differentiated foundry solutions.

Qualifications

• Bachelor’s degree in Electrical Engineering, Microelectronics, Physics, Applied Physics, or related field.
• Minimum 5 years of experience applying semiconductor device physics to device modeling, transistor compact-model development, parameter extraction, device characterization, or related work.
• Strong background in semiconductor device physics and transistor compact modeling including short-channel effects, leakage, capacitance, variability, and temperature dependence.
• Experience developing or applying models for superconducting and photonic elements, including parameterization and deployment in simulation environments.
• Hands-on experience with compact-model parameter extraction and model validation using measured data.
• Proficiency with SPICE-class circuit simulation and EDA tools.

Responsibilities

• Develop and calibrate physics-based compact models for CMOS and related transistors across room-temperature and cryogenic regimes.
• Develop, calibrate, and validate simulation-ready models for superconducting and photonic elements using measured data and physical mechanisms.
• Plan and execute parameter-extraction and model-validation workflows from device test structures and test chips.
• Correlate model behavior with data, device physics, and TCAD or other physics-based simulations; identify limitations and drive improvements.
• Define device and test-structure requirements to extract, validate, and improve models for cryogenic design enablement.
• Integrate and qualify model files within PDK and EDA environments, including regression testing and release readiness.
• Analyze temperature-dependent device behavior, variability, and reliability, guiding circuit designers.
• Collaborate with device engineering, technology development, PDK, EDA, and circuit-design teams on model requirements.
• Communicate model assumptions, validation results, and usage recommendations through technical reports and documentation.
