Job summary

Nu Quantum Ltd. in Cambridge, UK, is seeking a Principal AMO Physicist to lead the AMO team within hardware engineering. You’ll work on trapped‑ion testbeds interfacing microcavity‑technology with ion qubits to benchmark ion‑photon interfaces and entanglement fidelity.

You’ll mentor researchers, design experiments, and drive system‑level integration across optics, electronics, and mechanical design while shaping the long‑term quantum networking roadmap.

Qualifications

• Experience in experimental AMO physics, preferably in ion‑trapping.
• Hands‑on quantum control of qubits with optical fields.
• Strong understanding of qubit control and atom–phonon interactions.

Responsibilities

• Design and execute remote‑entanglement experiments to benchmark and advance ion‑trapping devices with Nu Quantum’s integrated micro‑cavity technology.
• Mentor and support AMO Physicists, helping them grow technical depth, independence, and problem‑solving capability.
• Develop, maintain, and troubleshoot laboratory systems — including laser setups, RF/DC electronics, control systems, and ultra‑high‑vacuum hardware.
• Collaborate across disciplines with Software, Optical, Mechanical, and Electrical Engineers, as well as with theory and simulation teams, to deliver integrated experimental systems.
• Keep project teams and Project Management Office aligned through clear, timely communication of results, progress, and priorities across interdependent, fast‑moving workstreams.
• Establish and uphold best practices in laboratory safety, documentation, and system reliability.
• Contribute to technical strategy, identifying opportunities to improve experimental design, automation, and scalability.
