Role Purpose

The Lead Solution Architect will drive the end-to-end solution architecture for the enterprise insurance modernisation programme, spanning policy administration, claims, digital engagement, integration, data, and operational platforms.

The role will translate target enterprise architecture principles into executable, scalable, and resilient solution designs that enable a client-first, API-first, and event-driven ecosystem.

This role partners closely with the Enterprise Architect and wider architecture team, domain leaders, engineering teams, and vendors to ensure architectural integrity, delivery coherence, and long-term sustainability of the modernised insurance platform landscape.

There is already a clear, sensible strategic direction in place, with meaningful progress made. The expectation for the Lead (and the broader team) is to build on that foundation, not to discard or restart it. Their role is to strengthen, accelerate, and operationalise what’s already been defined — ensuring continuity, stability, and incremental evolution. Any improvements should be evidence-based and respectful of the current architecture and organisational context.

Technology Environment

The Modernisation Programme Operates Within a Predominantly

• Java-based application ecosystem
• AWS cloud environment
• API-first and event-driven integration model
• BPM and decision management platforms
• Containerised deployment (e.g., Kubernetes)

Candidates should demonstrate experience designing solutions in comparable enterprise technology environments.

Requirements

• 12 years in enterprise solution architecture.
• Experience in large-scale insurance or financial services transformation.
• Proven track record in modernising legacy ecosystems.
• Deep experience with:
  • API-led and event-driven architectures
  • BPM / workflow platforms
  • Decision engines / rules management
  • Cloud-native and microservices architecture
  • Enterprise integration patterns
• Experience working in board-visible transformation programmes.

Experience Modernising Legacy Platforms In Brownfield Enterprise Environments Is Highly Desirable, Including Use Of Incremental Migration Strategies And Architectural Decomposition Approaches Including

• Modular decomposition in brownfield environments.
• Strangler patterns.
• Anti-corruption layers.
• Transitional architectures.
