Cryogenic & Photonics Quantum Device Modeling Engineer

GlobalFoundries inc.; Essex Junction (VT); On-site; USD 98,000 - 176,000; Full time

Job summary

GlobalFoundries seeks a Device Modeling Engineer to develop predictive models for superconducting and other quantum-enabled devices. You will translate device physics into simulation-ready models for QPDKs and heterogeneous integration, enabling customer design flows.

Responsibilities include model extraction/validation using electrical, optical, RF, and cryogenic data, and implementing models in circuit and photonic environments. Collaboration with multiple teams is essential.

Qualifications

• Bachelor's degree in Electrical Engineering or related field.
• 5+ years in device physics and non-CMOS device modeling.
• Strong semiconductor physics knowledge and predictive modeling ability.
• Hands-on modeling of non-CMOS devices (e.g., Josephson junctions, photonics).
• Experience correlating models with measurements across electrical/optical/RF/cryogenic data.
• Programming in Python or MATLAB in a Linux/Unix environment.
• Experience with at least one of the listed simulation environments.

Responsibilities

• Develop physics-based, behavioral, and compact models for non-CMOS devices.
• Plan model extraction and validation using electrical, optical, RF/microwave, and cryogenic data.
• Correlate model behavior with measured data and drive improvements.
• Define device structures and parameters for scalable models across conditions.
• Implement models in circuit, EM, and photonic simulators with validation and release.
• Develop model libraries and design collateral for QPDKs and integration platforms.
• Collaborate with cross-functional teams to translate technologies into design capabilities.
• Document assumptions, validation results, and usage guidance in reports.
