Job description

We're looking for an experimental Physicist to join our AMO physics team in building a quantum‑network demonstrator. This cross‑functional, hands‑on role spans atomic physics, cavity QED, and quantum engineering, requiring collaboration with electronics, optics, mechanical design, software, and theory / simulation teams.

Responsibilities

• Execute remote‑entanglement experiments to benchmark and advance ion‑trapping devices with Nu Quantum's integrated micro‑cavity technology.
• Support other AMO Physicists, helping the team grow technical depth, independence, and problem‑solving capability.
• Maintain and troubleshoot complex laboratory systems—laser setups, RF / DC electronics, control systems, and UHV hardware.
• Collaborate across disciplines with Software, Optical, Mechanical, and Electrical Engineers, and theory / simulation teams, to deliver integrated experimental systems.
• Communicate results, progress, and priorities across interdependent, fast‑moving workstreams.
• Uphold best practices in laboratory safety, documentation, and system reliability.
• Participate in the development of technical strategy, identifying opportunities to improve experimental design, automation, and scalability.

Qualifications

• Experience in experimental AMO physics, preferably in ion‑trapping or a related discipline.
• Understanding of qubit control, atomic physics, atom‑phonon interactions, or gate optimisation / benchmarking.
• Experience working with optical, electronic, and UHV systems.
• Understanding of laser locking, system automation, or real‑time control (e.g., ARTIQ).
• A system‑level mindset—comfortable connecting hardware, software, and control layers.
• Collaborative communication skills, confident to take initiative, make independent technical decisions, and drive solutions forward.

Bonus Points

• Experience within a collaborative team delivering complex projects in a fast‑paced environment.
• Contributions to project proposals, technical roadmaps, or long‑term projects.
• Experience with scientific communication (papers, talks, conferences).
• Experience with cavity QED.

Benefits

• Nu Quantum is at the forefront of quantum computing and advanced technology, driven by innovation, diversity, and a commitment to excellence.
• Flexible working options.
• Group DIS cover (4× salary).
• One‑month paid sabbatical after 4 years of service.
• Generous employee referral scheme.
• Private medical and dental cover (Vitality and Bupa).
• On‑site gym membership.
• Cycle scheme.
• Refreshments—including fruit and beverages—in the office.
• 28 days annual leave, including a 3‑day company shutdown period + UK public holidays.
• Option to purchase up to 5 days holiday per year.
• Enhanced paid family leave policies.
• Access to the Cambridge Botanical Garden.
