About Squarcle / The Team
Squarcle is a growing strategy, operations and digital consultancy dedicated to driving the performance of our clients. We are people-orientated and pride ourselves on our people-first culture. Unlike many consultancies, Squarcle is as equally dedicated to delivery as it is to design.
The Digital Capability provides expert technology, digitisation strategy, architecture, service design, operational optimisation and analysis advice to clients operating in fast-moving, regulated and high-security environments. The team works across digital strategy, enterprise and solution architecture, systems integration, data, service transition, operational support and technology-enabled transformation.
Working collaboratively or independently, team members engage directly with clients, both onsite and remotely, to resolve complex and strategically important challenges. Squarcle is committed to equality and diversity. Our aim is to build a diverse, dedicated and high-performing team of subject matter experts to help clients achieve supply chain and operational excellence.

Job Overview / Introduction
As a NATO Enterprise Architect, you will support Squarcle’s digital and defence growth by shaping enterprise, solution and service architectures for complex NATO, MOD and wider defence clients.
The role will be particularly important in supporting NATO and NCIA opportunities involving logistics information services, operational support systems, service management, secure environments and integration with NATO functional systems, including LOGFAS and related legacy applications.
You will operate across bid, mobilisation and delivery phases, helping Squarcle interpret client requirements, define credible technical and service delivery approaches, shape transition and operating models, and assure that proposed solutions are secure, supportable, interoperable and deliverable within classified, multi-national and mission-critical environments.
The role requires a blend of enterprise architecture, service delivery management, defence logistics awareness, systems integration, ITSM and bid leadership. The successful candidate must be comfortable working with senior stakeholders, delivery teams, partners and client representatives to turn complex operational requirements into clear, compliant and compelling solution responses.
Role purpose: To help Squarcle shape, win and deliver complex NATO and defence digital programmes by combining enterprise architecture, service delivery management, secure environment design, systems integration and operational logistics awareness.
Primary Roles And Responsibilities

- Provide strategic technology and service delivery advice to senior client stakeholders, clearly articulating trade-offs, risks, assumptions, dependencies and recommendations.
- Develop compelling bid narratives, technical responses, service management approaches, delivery models, acceptance strategies and mobilisation plans.
Enterprise, Solution and Service Architecture
- Define and maintain target enterprise, solution and service architectures for client organisations, ensuring alignment with business strategy, operating models, mission outcomes and regulatory context.
- Develop multi-year technology and service roadmaps spanning applications, data, infrastructure, integration, security, support and operational transition.
- Establish and govern architecture principles, standards, reference models and secure patterns that drive consistency, re-use and architectural coherence across programmes and portfolios.
- Create architecture artefacts including capability maps, application and data landscapes, integration blueprints, environment models, service models, operating models and transition plans.
