Join Nu Quantum - Shaping the Future of Technology

Nu Quantum is creating the Entanglement Fabric for quantum computing scale-out. Quantum computing can solve some of the world’s biggest problems, but these applications require systems that are thousands of times more powerful than those available today.

Our networking architecture will unlock data centre-scale quantum computing by weaving together quantum processors to accelerate the path to fault-tolerance and transformational utility. Founded in 2018, Nu Quantum is a spin-out of the University of Cambridge’s Cavendish Laboratory.

We are looking for a Senior Mechanical Engineer to join our highly collaborative team, to support the development of our novel quantum networking hardware. The successful candidate will be working with, and supported by, teams spanning mechanical, electronic, optical, nanofabrication, software and physics.
