Principal Quantum Hardware Engineer

Microsoft Quantum has assembled a talented, diverse international team to build the world’s first scalable quantum computing system. Our full-stack approach spans innovation from the physics of the quantum plane to the delivery of global quantum services. The Microsoft Quantum program aims to fundamentally transform computing to help solve some of humanity’s most intractable problems as we enter an accelerated era of quantum advancement.      We are seeking talented, focused individuals to help deliver useful quantum computers. Microsoft is pursuing topological qubits for large-scale quantum computing and partnering with a growing ecosystem of companies to advance quantum systems across every layer of the stack and bring them to market through the Microsoft Quantum accelerator platform. We believe AI can speed up the development of useful quantum computers and shorten the path to their realization.       As a Principal Quantum Hardware Engineer experimentalist, you will help build, integrate, and operate cryogenic quantum hardware experiments in a forward-deployed quantum laboratory. You will work hands-on with dilution refrigerators, cryogenic and vacuum systems, RF/microwave control and readout chains, low-noise measurement infrastructure, device bring-up, and experimental automation. This role partners closely with scientists, hardware engineers, systems architects, program managers, and ecosystem partners to accelerate experimental learning and advance Microsoft’s path toward useful quantum computing.      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.
