Principal Solutions Architect

We’re looking for a seasoned Principal Solutions Architect to provide architectural leadership across a major  platform modernisation programme. This is our highest‑priority strategic initiative and sits at the heart of a wider organisational transformation spanning finance, operations, commercial, contact centre, technology, product, revenue management and fraud domains. 

In this role, you will guide the end‑to‑end architecture of a cloud‑native, AWS‑hosted ecosystem, ensuring strategic alignment, technical governance, and a coherent target state across multiple autonomous product teams. You’ll combine enterprise‑level architectural leadership with hands‑on support, helping teams navigate complex design decisions, cross‑domain dependencies, and the replacement of a large legacy monolith under fixed commercial timelines. 

The role requires both breadth and depth across application, data, integration, security and cloud architecture, along with strong stakeholder leadership in a politically complex environment.
