Quantum Computing Jobs in Cambridge

Cambridge has the highest concentration of quantum computing companies and research groups in the UK. The cluster extends from the city centre out along the M11 corridor, with hardware, software and investor activity unusual for a town this size.

Cambridge is the densest quantum cluster on the FTJ network. Roles here span the full stack — from trapped-ion physicists and cryogenic-systems engineers, to QEC researchers and quantum-software developers, to the applied-research and product teams at Riverlane, Quantinuum, Phasecraft and a growing list of spin-outs from the university's physics and computer-science departments.

Expect a higher proportion of on-site and hybrid roles than the UK average — most of the work involves real hardware, not just simulation. Pay tilts toward the upper end of the UK distribution because the candidate pool is small and competition between Cambridge employers is fierce, especially at senior level.

The scene

Hiring in Cambridge

Cambridge is the densest quantum cluster on the FTJ network. Riverlane, Quantinuum, Cambridge Quantum, Phasecraft and a handful of academic spin-outs hire here regularly — most within a short walk or cycle of each other in the centre or on the West Cambridge campus.

Roles here lean on-site or hybrid: a lot of the work is lab-based or sits close to hardware teams. Expect employers to prefer candidates already in or moving to Cambridge / the wider East Anglia commute, with hybrid arrangements typically 3–4 days a week in person.
