The Role
We’re looking for a seasoned Principal Solutions Architect to provide architectural leadership across a major finance platform modernisation programme. This role sits at the core of transforming our finance technology landscape, covering domains such as core financials, billing, payments, revenue management, and financial data services.
In this role, you will guide the end‑to‑end architecture of a cloud‑native, AWS‑hosted finance ecosystem, ensuring strong alignment to financial processes, regulatory requirements, and enterprise technology standards. You will establish clear technical governance and drive a coherent target state across multiple autonomous teams delivering finance capabilities.
You’ll combine enterprise‑level architectural leadership with hands‑on support, helping teams navigate complex financial workflows, data integrity challenges, and integration patterns across finance systems. A key focus will be enabling the transition from legacy finance platforms to a modern, scalable, and auditable architecture, while supporting ongoing financial operations and reporting needs.
The role requires both breadth and depth across application, data, integration, security and cloud architecture, alongside a strong understanding of finance platforms, controls, and compliance considerations. You’ll also bring strong stakeholder management skills, working closely with finance, technology, and product leaders to shape and deliver a robust financial systems architecture.
