Lead Architect

As JTC enters the Genesis era of growth andtransformation under private equity ownership, the Group’s ambition is tobecome a data- and AI-powered specialist-services platform where everyinteraction, acquisition and piece of expertise makes the firm smarter, moreefficient and easier to scale.

The Lead Architect sits within Application Architecture, part of the Technology Strategy & Application Architecturefunction within JTC’s unified Tech-AI operating model.

The role owns JTC’starget-state application architecture and leads the design of solutionarchitecture for priority initiatives, working across an estate that has beenbuilt up through acquisition and contains duplicated systems and point-to-pointintegrations requiring active rationalisation.

The postholder will provide architecture inputinto buy-vs-build and vendor decisions, including evaluating third-party andembedded AI tools, and will design the solution architecture for priorityinitiatives, working closely with AI Engineering & Data Science and Group Data so that AI, agentic and data platform components are built onto the estatecoherently and without creating vendor lock-in.

As JTC continues to grow byacquisition, the role also covers assessing new acquisitions’ technology estatesagainst the target architecture and helping prioritise what gets integratedfirst.

• MAIN RESPONSIBILITIES AND DUTIES
• Define and own JTC’s target-state application architecture, rationalising a fragmented, acquisition-built estate of duplicated systems and point-to-point integrations.
• Provide architecture input into buy-vs-build and vendor decisions, including evaluating third-party and embedded AI tools for fit with the Group’s data and application estate.
• Establish architecture standards, integration patterns and principles, and run or contribute to the architecture governance forum for the Group.
• Assess new acquisitions’ technology estates against the target architecture and help prioritise what gets integrated first.
• SOLUTION ARCHITECTURE & DELIVERY
• Design the solution architecture for priority initiatives, translating the target architecture into delivery-ready designs.
• Work hands-on across specific integration and delivery projects, including those spanning multiple existing systems being consolidated or replaced.
• Partner directly with AI Engineering & Data Science and Group Data on the architecture of agentic and data platform components, ensuring AI capability is built onto the estate coherently and without creating vendor lock-in.
• AI & AGENTIC ARCHITECTURE
• Maintain current, practical fluency in agentic and AI architecture patterns, including orchestration, retrieval and grounding, and MCP-style integration, sufficient to credibly shape how these fit he wider estate.
• Contribute architecture positions on AI-related integration, data dependencies and target-state implications as new agentic capabilities move from prototype into production.
• REGULATORY & RISK AWARENESS
• Make architecture decisions with awareness of JTC’s regulated, multi-jurisdiction footprint, recognising that data residency, cross-border transfer and compliance requirements vary by jurisdiction and should be confirmed with Compliance and Legal rather than assumed.
• DOCUMENTATION & CAPABILITY BUILDING
• Document architecture decisions, standards and patterns clearly enough to be usable by other teams without ongoing explanation.
• Contribute to theongoing development of the Application Architecture capability as the team andfunction grow.

ESSENTIAL REQUIREMENTS

• Senior architecture experience that includes real exposure to target-state and governance decisions, combined with current, hands-on solution design experience from within the last one to two years.
• Experience operating in a fragmented, multi-entity, acquisitive estate rather than a greenfield environment, ideally including consolidation of point-to-point integrations.
• Demonstrable experience contributing to buy-vs-build and vendor decisions, including evaluating embedded AI or Saa S tools.
• Current, practical fluency in AI and agentic architecture patterns, sufficient to partner credibly with AI engineering teams.
• Strong modern solution design experience, including cloud-native architecture, APIs and integration patterns.
• Experience in a regulated, multi-jurisdiction environment, ideally Financial Services or Professional Services, with sound judgement on when to involve Compliance and Legal.
• Experience with technology integration during M&A or acquisition-driven growth is highly advantageous.
• Strong written communication skills, able to produce documentation and standards that are usable by others without ongoing explanation.
• Comfortable operating without a large architecture team, moving between strategic and hands-on delivery work as needed.
• A relevant degree in computer science, engineering or a related discipline, and relevant professional certifications, are valued but not required.
