Hybrid – London
Our client, an international professional services organisation, is undergoing a significant technology transformation and is investing heavily in its Architecture capability. As part of this growth, they are looking to appoint a Senior Solution Architect to help shape the future of their technology landscape.
This is a rare opportunity to join an organisation at a relatively early stage in its architecture maturity, where you'll play a key role in defining standards, influencing technical direction, mentoring others, and helping establish architectural best practice across the business. Alongside delivering complex enterprise solutions, you'll also contribute to the organisation's AI foundations, helping ensure the technology estate is ready to support future AI capabilities and innovation.
The Role
Reporting into the Head of Architecture, you'll work across strategic transformation programmes, partnering with business leaders, engineering teams, and fellow architects to design scalable, secure, and resilient technology solutions.
This role combines hands-on solution architecture with the opportunity to influence the wider architecture function, helping to build processes, governance, and standards as the capability continues to mature.
