What you will do

• Develop physics-based, behavioral, and compact models for superconducting, photonic, optoelectronic, cryogenic passive, and other emerging non-CMOS devices.
• Plan model-extraction and validation workflows using electrical, optical, RF/microwave, and cryogenic characterization data.
• Correlate models with measured data, multiphysics simulations, and device physics; identify limitations and drive corrective actions.
• Define device structures, process parameters, and characterization vehicles for scalable validation across geometry, temperature, frequency, wavelength, and operating conditions.
• Implement and qualify models in circuit, electromagnetic, and photonic simulation environments, including regression testing, convergence checks, documentation, and release readiness.
• Develop QPDK and heterogeneous-integration model libraries and design collateral, and collaborate with device, process, packaging, PDK, EDA, and circuit-design teams.

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 the ability to translate physical behavior into predictive simulation models.
• Hands-on experience modeling at least one non-CMOS device class, including 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 with 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 an equivalent tool.
• Ability to communicate technical conclusions clearly to device, process, characterization, PDK, EDA, and design stakeholders.
• Fluent written and verbal English; willingness to travel up to 10%.

Nice to have

• Master’s degree or PhD in a related engineering, physics, photonics, microelectronics, or quantum-engineering field.
• Experience with superconducting devices, photonic or optoelectronic elements, equivalent-circuit or compact models, behavioral or reduced-order models, electromagnetic or multiphysics modeling.
• Knowledge of cryogenic material behavior, RF/microwave effects, optical loss and dispersion, variability, parasitics, thermal effects, and model convergence.
• Experience with Verilog-A, SPICE subcircuits, photonic compact-model libraries, QPDK/PDK releases, model QA, regression testing, version control, and customer-facing documentation.
• Familiarity with heterogeneous integration, advanced packaging, superconducting interposers, quantum interconnects, or electrical, optical, thermal, and electromagnetic co-simulation.
• Project management, innovation, solution execution, ambiguity management, communication, planning, and organizational skills.
