Working closely with Enterprise Architects, Solution Architects, Engineering teams and senior business stakeholders, you'll establish the vision, standards and roadmap that underpin a modern, scalable and resilient integration capability.

This is a highly influential architecture leadership role where you'll balance strategic thinking with pragmatic delivery, helping drive technology simplification while enabling innovation across digital, retail and customer platforms.

What You'll Be Doing

• Define and own the enterprise integration strategy, architecture roadmap and target state.
• Establish best practice, standards and governance across APIs, messaging, event-driven architecture, orchestration and enterprise integration.
• Lead architectural direction for integration platforms, ensuring solutions are secure, scalable, observable and resilient.
• Provide architectural leadership and guidance to Solution Architects, engineering teams and delivery partners.
• Drive reuse and consistency across integration services while reducing technical debt and unnecessary point-to-point integrations.
• Collaborate across business and technology teams to support major transformation programmes and strategic initiatives.
• Contribute to architecture governance, design authority and technology investment decisions.
• Assess emerging technologies, including AI-enabled integrations, ensuring they align with enterprise standards and security requirements.
• Mentor architects and champion architecture excellence across the organisation.

You’ll bring:

• Demonstrable extensive experience in architecture, enterprise integration or technology leadership.
• A strong background within eCommerce
• Deep expertise designing enterprise integration architectures across cloud, SaaS, on-premise and legacy platforms.
• Excellent knowledge of API architecture, event-driven design, messaging, integration patterns and modern architectural principles.
• Experience with technologies such as Azure Integration Services, Azure API Management, Service Bus, or similar enterprise integration platforms.
• Strong understanding of hybrid cloud integration, security, resilience, observability and operational excellence.
• Experience with architecture frameworks and modelling approaches such as TOGAF, UML, etc.
• The ability to influence senior stakeholders and communicate complex technical concepts clearly.
• A collaborative leadership style with experience mentoring architects and engineering teams.
