Lead Solution Architect – Large-Scale Transformation
A major platform transformation is underway — moving from legacy systems to a modern, scalable, event-driven architecture. This role sits at the heart of that journey, shaping both the target state and how it’s delivered.
You’ll operate as a senior technical authority, balancing strategic architecture with hands‑on leadership across a complex, high‑dependency environment.
Responsibilities
* Own and define end-to-end solution architecture across a multi-year transformation programme
* Set the architectural direction for modern, scalable, and platform-independent systems
* Act as the senior bridge between enterprise architecture and engineering delivery teams
* Establish standards, patterns, and governance for the evolving technology landscape
* Ensure consistency and integration across legacy and modern platforms
* Lead architecture reviews, solution walkthroughs, and key technical decisions
* Drive proofs‑of‑concept and prototype development to validate critical design choices
* Provide hands‑on technical leadership (Java), while mentoring and guiding engineering teams
* Engage senior stakeholders, clearly articulating architecture decisions, trade‑offs, and risks
Requirements
* Extensive experience in solution architecture within complex, enterprise-scale environments
* Strong hands‑on background in Java and object-oriented design
* Deep experience with event-driven architectures (Kafka or similar)
* Strong understanding of integration patterns and system interoperability
* Experience working with containerised environments (OpenShift, Kubernetes, etc.)
* Ability to operate at both strategic and hands‑on levels
* Experience in regulated or high-availability environments
* Exposure to large-scale system modernisation or migration programmes
* Familiarity with messaging standards and distributed data systems
This is a good opportunity to shape foundational infrastructure in the evolution of digital assets within regulated financial services.
