Principal Signal Integrity Simulation Engineer

What you'll do

• Lead the end-to-end signal integrity simulation strategy for quantum systems across room-temperature and cryogenic environments.
• Develop system-level models to predict signal fidelity, crosstalk, timing, noise, and bandwidth limitations.
• Conduct architecture trade studies and design decisions using simulation-based analysis to identify risks before hardware implementation.
• Establish modeling standards and validation practices using electromagnetic, circuit, behavioral, and system-level tools.
• Define interface requirements and performance metrics for Cryo-CMOS, packaging, and qubit design teams.
• Document designs and methodologies to ensure reproducibility and seamless integration across the organization.
• Utilize Python-based automation and AI tools to accelerate modeling, simulation, and data analysis workflows.

What we're looking for

• A Doctorate in Electrical Engineering or Physics with 3+ years of experience, a Master's with 6+ years, or a Bachelor's with 8+ years is required.
• Candidates must provide proof of citizenship or U.S. permanent residency to access export-controlled information.
• Must be able to pass the Microsoft Cloud Background Check and meet government security screening requirements.
• Extensive experience in signal integrity, RF engineering, electromagnetic simulation, or system-level modeling is required.
• Experience using industry-standard tools like Cadence, Ansys HFSS, Keysight ADS, AWR, COMSOL, or SPICE-based tools is required.
• Experience with cryogenic electronics, Cryo-CMOS systems, superconducting systems, or quantum computing hardware is preferred.
• Proficiency in Python-based simulation, automation, and data analysis workflows is required.
• Master's Degree in Electrical Engineering, Physics, or related field AND 6+ years technical engineering.
