About The Position

At Microsoft Quantum, we aim to empower science and scientists to solve the world’s biggest problems by realizing advanced computing platforms at the intersection of high-performance computing, artificial intelligence, and quantum information technology. Microsoft Quantum will change the world of computing and help solve some of humankind’s currently unsolvable problems. Microsoft Quantum is building the world’s first scalable quantum computing system, with a full-stack approach spanning materials, devices, systems, and cloud services. Our hardware strategy is centered on topological qubits, which require sophisticated nanofabrication of hybrid semiconductor–superconductor devices with stringent control of interfaces, materials quality, and process integration. We are seeking a Principal Quantum Materials Engineer to lead the development of superconductor-semiconductor heterostructure that directly enable topological qubit performance and scalability. This role is central to translating materials innovation into device-level and system-level impact and carries significant technical ownership across the materials stack. You will work closely with experts in device physics, modeling, and characterization teams, operating in a fast-paced, highly interdisciplinary R&D environment. Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
