Neutral Atom Systems Architect

Nu Quantum is seeking a highly skilled Neutral Atom Systems Architect to lead on the specification and architecture of a Quantum Networking layer that supports Distributed Quantum Computing with Neutral Atoms.

The successful candidate will join a highly collaborative environment. Working closely with our AMO theorists, networking team, QEC researchers and Systems engineers, to define how Nu Quantum's hardware interfaces with Neutral atom QPUs, from modelling high-fidelity networking protocols through to hardware-performance targets that will enable fault-tolerant distributed quantum computing.

The role will involve collaborating with peers across the organisation and coordinating with external partners, helping shape the path towards large-scale QC Systems.

Responsibilities

• System Architecture & Specs: Own the definition, decomposition, and maintenance of the Network System Architecture and all System/Subsystem Specifications (QPI, QNU, Cavity Systems, etc.) for Neutral Atoms. You define what the system must do to create a clean, well-documented specification for the engineering team.

• Own the technical vision for neutral-atom hardware architecture, and the company's go-to expert for qubit control, optical systems, gate optimisation and overall system performance.

• Provide technical leadership building on your technical expertise to assist with system architecture, hardware design concepts, hardware specification targets, technical decision-making and project scoping.

• Working with AMO theorists to model high-fidelity remote entanglement generation and networking protocols under realistic experimental constraints.

• Collaborating with the Quantum Error Correction team to define architectural requirements for distributed fault-tolerant quantum computing.

Cross-Functional Alignment: Work closely with the Product Management team to ensure specifications meet commercial product definitions, and with the Engineering team to convey clear concepts of operation for the Networking Hardware.

• Act as the technical partner for Product Managers, evaluating competing quantum networking approaches, providing system-level analysis to inform product strategy and technology roadmaps.
• Align with Heads of Departments and Group Leads to help them identify critical skill gaps to scale our world-class engineering team.
• Meeting with the Project Management Office and Finance teams to coordinate initial project scoping, resource allocation and tooling.

Embodying our company values, championing scientific integrity and fostering a collaborative working environment.

Furthermore, there will be opportunities for you to represent the company at scientific conferences and industry events.

• Postgraduate qualification (PhD preferred) in Physics, with applications to neutral-atom quantum computing.
• Deep technical expertise in neutral-atom quantum computing, incl. design and operation of neutral-atom quantum processing units.
• Strong understanding of laser physics, optical engineering and experimental techniques required for neutral-atom systems, including optical trapping, beam delivery and laser stabilisation.
• Expertise in high-fidelity neutral-atom qubit gates, including Rydberg-mediated entangling gates, error mechanisms and performance optimisation.
• Strong understanding of quantum control, calibration and system-level optimisation across hardware and software interfaces.
• Experience modelling open quantum systems using tools such as QuTiP, Mathematica, MATLAB, Python or equivalent.
• Experience leading technical projects and taking responsibility for technical delivery, architectural decisions and budget planning (for example as a Technical Lead in industry, Group Leader in academia, or equivalent).
• Excellent communication skills (written and verbal).
• Strong data management skills and experience working within multidisciplinary teams.

Other (Desirable but not required)

• Knowledge of photonic interfaces between neutral atoms and quantum networks.
• Understanding of distributed quantum computing architectures and quantum networking protocols.
• Knowledge of Quantum Error Correction and fault-tolerant quantum computing architectures.
• Industry experience.

• Flexible working options

• Group DIS cover (4 x salary)

• 1 month paid Sabbatical after 4 years of service

• Generous Employee Referral Scheme

• Private Medical and Dental Cover (With Vitality and Bupa)

• On-site gym membership

• Cycle scheme

• Refreshments, including fruit and beverages, are available 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 Gardens
