We are looking for an experienced Solution Architect to join a complex technology transformation programme within a large enterprise environment.

The role will focus on understanding the existing technology landscape, assessing current capabilities and constraints, defining future-state architecture and developing a practical roadmap for implementation.

You will work across architecture, technology, integration and delivery, engaging with both technical teams and senior business stakeholders.

  • Develop and evaluate technology and architectural options.
  • Define target-state architecture and technical principles.
  • Identify technical risks, dependencies and opportunities for simplification.
  • Translate business requirements into appropriate technical solutions.
  • Work closely with engineering teams to validate architectural decisions.
  • Support technical prototypes and proof-of-concepts where required.
  • Produce clear architecture documentation and implementation roadmaps.
  • Facilitate technical workshops and stakeholder discussions.
  • Support delivery teams through the transition from architecture into implementation.

Essential Experience

  • Strong commercial experience as a Solution Architect or Technical Architect.
  • Experience designing and assessing complex distributed systems.
  • Strong understanding of APIs, integrations and event-driven architectures.
  • Experience with modern application and cloud technologies.
  • Strong understanding of software development principles and architecture.
  • Experience assessing existing systems and developing practical improvement strategies.
  • Comfortable working where requirements or documentation may initially be incomplete.
  • Strong stakeholder management and communication skills.
  • Able to explain complex technical concepts to technical and non-technical stakeholders.

Desirable Experience

  • GCP or other cloud platforms.
  • Java / JVM technologies.
  • Microservices architecture.
  • Event-driven architecture.
  • Data and integration platforms.
  • Enterprise technology transformation or modernisation programmes.
  • Experience within large, complex or regulated organisations.

This role would suit a pragmatic architect who is comfortable working at both strategic and detailed technical levels and can confidently challenge assumptions and make evidence-based recommendations
