Quantum Device Modeling Engineer

Job Title

Quantum Device Modeling Engineer

Role Summary

Develop, validate, and deliver predictive models and model libraries for superconducting, photonic, optoelectronic, cryogenic passive, and other emerging quantum-enabling devices. Models will be integrated into Quantum Process Design Kits (QPDKs), simulation flows, and customer design environments to enable design and heterogeneous integration.

Experience Level

Mid-level. Minimum 5 years of relevant experience in device physics, device modeling, multiphysics simulation, parameter extraction, or characterization of non-CMOS devices.

Responsibilities

Translate device physics and measurement data into simulation-ready models and integrate them into design flows and libraries.

• Develop physics-based, behavioral, compact, and reduced-order models for superconducting, photonic, optoelectronic, and cryogenic passive devices.
• Plan and execute model-extraction and validation workflows using electrical, optical, RF/microwave, and cryogenic data.
• Correlate models with measured device data and multiphysics simulation; identify limitations and implement corrective actions.
• Define device structures, process parameters, and test vehicles needed to extract scalable models across geometry, temperature, frequency, and wavelength.
• Implement and qualify models in circuit, electromagnetic, and photonic simulation environments; perform regression testing and convergence checks.
• Produce model libraries and design collateral (symbols, parameter sets, interfaces, usage guidance) for QPDKs and integration platforms.
• Collaborate with device, process, integration, characterization, packaging, PDK, EDA, and circuit-design teams to enable customer design flows.
• Document model assumptions, validation results, known limitations, and usage guidance via technical reports and application notes.
• Follow safety and Environmental, Health, Safety & Security requirements; support other projects as needed.

Requirements

Must-have technical skills and experience required to perform the role.

• Minimum 5 years experience in device physics, device modeling, multiphysics simulation, parameter extraction, or characterization of non-CMOS devices (superconducting, photonic, optoelectronic, RF/microwave, or cryogenic).
• Strong foundation in semiconductor and solid-state device physics and ability to convert physical behavior into predictive simulation models.
• Hands-on experience modeling at least one non-CMOS device class (examples: Josephson junctions, SQUIDs, superconducting resonators/interconnects, waveguides, modulators, ring resonators, photodetectors, lasers, cryogenic passives).
• Experience correlating models with measured electrical, optical, RF/microwave, or cryogenic data and defining validation criteria across operating ranges.
• Proficiency in scientific programming and data analysis (Python, MATLAB, or equivalent) in a Linux/Unix environment.
• Experience with one or more simulation environments (COMSOL, Ansys HFSS, Ansys Lumerical, Keysight ADS, Cadence Virtuoso/Spectre, or equivalents).
• Ability to communicate technical conclusions clearly to cross-functional stakeholders; strong written and verbal English.
• Willingness to travel up to 10%.
• Preferred: familiarity with model QA practices, regression testing, version control, and customer-facing documentation.
• Nice-to-have: experience with heterogeneous integration, advanced packaging, superconducting interposers, or co-simulation across electrical/optical/thermal/electromagnetic domains; project management skills.

Education Requirements

Required: Bachelor's degree in Electrical Engineering, Applied Physics, Physics, Photonics, Microelectronics, Quantum Engineering, or a related field. Preferred: Master's degree or PhD in the same or closely related fields.
