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 Senior Quantum Materials MBE Engineer to develop and optimize MBE growth processes that enable high-quality quantum materials and devices. This role focuses on execution excellence, experimental rigor, and cross-functional collaboration, contributing directly to improvements in qubit performance and scalability. 

You will work closely with experts in device physics, modeling, fabrication, and characterization in a fast-paced, 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.
