## About the Role

To advance our quantum technology initiatives, we are seeking a Senior Quantum Engineer, Hybrid Interconnect to pioneer technologies for scaling quantum systems through modular and heterogeneous interconnects. The ideal candidate will have a strong background in quantum devices and interfaces, with expertise in one or more areas such as quantum transduction, single-photon detection, quantum memory, and solid-state qubit interfaces to optical or microwave photons. Experience in device design, fabrication, and characterization is highly desirable. This role will focus on developing novel devices, materials, and integration technologies for coherent quantum interconnects, leveraging advanced semiconductor fabrication to bridge different quantum modalities and enable scalable, modular quantum architectures.

## Description

* Pathfind and develop hybrid quantum interconnect technologies for scalable and modular quantum systems.
 * Design and develop devices for quantum transduction, single-photon detection, quantum memory, and solid-state qubit-to-photon interfaces.
 * Translate quantum-system and interconnect requirements into device, materials, fabrication, and integration specifications.
 * Design and characterize hybrid quantum devices and test structures, connecting device-level performance with system-level requirements.
 * Develop and optimize fabrication and integration processes involving superconducting, photonic, semiconductor, and other quantum materials and devices.
 * Investigate heterogeneous integration approaches that combine multiple quantum device technologies within scalable architectures.
 * Design experiments and perform electrical, optical, microwave, and cryogenic characterization, as appropriate for the device platform.
 * Analyze device performance and identify relationships among materials, interfaces, fabrication processes, and quantum performance.
 * Troubleshoot complex device and integration challenges and drive improvements in performance, reproducibility, and scalability.
 * Collaborate across quantum physics, photonics, superconducting devices, materials, process engineering, packaging, and system engineering.
 * Evaluate emerging quantum interconnect technologies and identify opportunities where advanced semiconductor manufacturing can enable system-level scaling.
