1d•$98,000 - $176,000

About The Position

GlobalFoundries is seeking a Device Modeling Engineer to develop, validate, and deploy predictive models for superconducting, photonic, optoelectronic, and other emerging quantum-enabling devices. The role translates fundamental device physics and measured electrical, optical, RF, and cryogenic behavior into simulation-ready models and libraries for Quantum Process Design Kits (QPDKs), heterogeneous integration, and customer design flows. The engineer will develop model libraries and design collateral, qualify models within circuit, electromagnetic, and photonic simulation environments, and work with cross-functional teams to turn emerging technologies into usable design capabilities. The role includes communicating model assumptions, validation results, limitations, and usage guidance through technical reports, application notes, and design reviews. Travel is up to 10%.

Requirements

Bachelor's degree in Electrical Engineering, Applied Physics, Physics, Photonics, Microelectronics, Quantum Engineering, or a related field.
At least 5 years of experience in device physics, device modeling, multiphysics simulation, parameter extraction, or characterization of superconducting, photonic, optoelectronic, RF/microwave, or other non-CMOS devices.
Strong foundation in semiconductor and solid-state device physics, with demonstrated ability to translate physical behavior into predictive simulation models.
Hands-on experience modeling at least one non-CMOS device class, such as Josephson-junction devices, SQUIDs, superconducting resonators or interconnects, waveguides, modulators, ring resonators, photodetectors, lasers, or cryogenic passive structures.
Experience correlating models with measured electrical, optical, RF/microwave, or cryogenic data and defining validation criteria across relevant operating ranges.
Proficiency in scientific programming and data analysis using Python, MATLAB, or equivalent tools in a Linux/Unix environment.
Experience with at least one relevant simulation environment, such as COMSOL Multiphysics, Ansys HFSS, Ansys Lumerical, Keysight ADS, Cadence Virtuoso/Spectre, or equivalent tools.
Ability to communicate technical conclusions clearly to device, process, characterization, PDK, EDA, and design stakeholders.
Fluency in written and verbal English.
Willingness to travel up to 10%.

Nice To Haves

Master's degree or PhD in Electrical Engineering, Applied Physics, Physics, Photonics, Microelectronics, Quantum Engineering, or a related field.
Experience modeling superconducting devices and structures, including Josephson junctions, SQUIDs, kinetic inductance, superconducting resonators, transmission lines, or qubit-adjacent circuit elements.
Experience modeling photonic or optoelectronic elements, including waveguides, couplers, modulators, ring resonators, photodetectors, lasers, or optical interconnects.
Experience with equivalent-circuit, compact, behavioral, reduced-order, electromagnetic, or multiphysics model development for design enablement.
Knowledge of cryogenic material behavior, RF/microwave effects, optical loss and dispersion, variability, parasitics, thermal effects, and model convergence challenges.
Experience with Verilog-A, SPICE subcircuits, photonic compact-model libraries, or other model formats used in circuit and system simulation.
Experience supporting QPDK, PDK, model-library, or design-kit releases, including model QA, regression testing, version control, and customer-facing documentation.
Familiarity with heterogeneous integration, advanced packaging, superconducting interposers, quantum interconnects, or co-simulation across electrical, optical, thermal, and electromagnetic domains.
Project management skills, including the ability to innovate, execute solutions that matter, and navigate ambiguity.

Responsibilities

Develop physics-based, behavioral, and compact models for superconducting, photonic, optoelectronic, cryogenic passive, and other emerging non-CMOS devices.
Plan and execute model-extraction and validation workflows using electrical, optical, RF/microwave, and cryogenic characterization data.
Correlate model behavior with measured device data, multiphysics simulation, and fundamental device physics; identify model limitations and drive corrective actions.
Define device structures, process parameters, and characterization vehicles needed to extract and validate scalable models across geometry, temperature, frequency, optical wavelength, and operating conditions.
Implement and qualify models within circuit, electromagnetic, and photonic simulation environments, including regression testing, convergence checks, documentation, and release readiness.
Develop model libraries and design collateral for QPDKs and heterogeneous integration platforms, including validated symbols, parameter sets, interfaces, and recommended design-use conditions.
Collaborate with device, process, integration, characterization, packaging, PDK, EDA, and circuit-design teams to translate emerging technologies into usable design capabilities.
Communicate model assumptions, validation results, known limitations, and usage guidance through technical reports, application notes, and design reviews.
Perform all activities safely and responsibly and support Environmental, Health, Safety & Security requirements and programs.
