Microsoft's mission is to empower every person and every organization on the planet to achieve more. 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. We are looking for a diverse set of talented and focused people to accelerate the delivery of useful quantum computers. Microsoft has an internal program pursuing topological qubits for large-scale quantum computing. We are also working closely with a growing list of companies to advance their qubit modalities and bring them to market on the Microsoft Quantum accelerator platform. The quantum product acceleration team is seeking a Principal Quantum Hardware Engineer to own key experimental milestone integration points on the path to a useful quantum computer. Your significant experience in quantum information technology from qubit design to fast qubit measurement to full-stack quantum computer experimental/theoretical demonstrations across different technologies will be required to execute technical development plans validating quantum plane technologies as they mature. You accelerate progress by owning key checkpoints that bridge the gap between the hardware engineers making qubits—such as topological, semiconductor, or superconducting qubits—with members of the architecture, software, and systems integration teams at Microsoft and with partner companies in the Microsoft Quantum accelerator platform. As a principal hardware engineer, you will be responsible for demonstrating dramatic improvements to future quantum computers in integrated systems. You will work alongside talented hardware and software engineers---both within Microsoft and with our partners---in a start-up like environment that values speed and people with broad skillsets.
