About The Position

Keysight is seeking a Senior Quantum EDA R&D Engineer to develop product features, design capabilities, and validated workflows for superconducting quantum hardware. This role is at the intersection of superconducting quantum hardware, microwave/RF engineering, EM simulation, and EDA product development. The ideal candidate will translate real hardware design problems into validated simulation workflows, application examples, and product capabilities. The role involves working with customers, product teams, and R&D colleagues to develop and validate superconducting hardware design methodologies in EDA environments and translate application needs into product features. Quantum hardware design is transitioning from one-off physics experiments to scalable engineering workflows, and Keysight aims to lead this transition by leveraging its expertise in microwave/RF, electromagnetic simulation, measurement, and EDA with emerging quantum design capabilities. This position will help shape design methodologies that integrate EM simulation, circuit modeling, Hamiltonian analysis, measurement correlation, and practical superconducting hardware workflows. Examples of Keysight's quantum EDA capabilities include QuantumPro for EM-driven qubit workflows and parameter extraction, ADS Quantum Layout for parameterized quantum artwork and chip buildup, Quantum Circuit Simulation for Josephson-junction-based circuits and quantum amplifiers, and Quantum System Analysis for virtual testbenching of quantum experimental setups. This is an opportunity to work where quantum device physics meets the engineering infrastructure required to scale real systems. Unlike a role focused on a single quantum hardware program, this role focuses on developing EDA capabilities that assist numerous superconducting quantum hardware teams in designing, simulating, validating, and scaling their systems. The engineer will transform hands-on quantum hardware and microwave/RF design insights into reusable tools, workflows, and product features, connecting device physics, EM/circuit simulation, Hamiltonian analysis, and measurement correlation within practical engineering environments.
