Lead Technical Architect in London

We're looking for multiple Lead Technical Architects who will play a central role in the successful delivery of technology projects. You will work closely with clients and internal teams to understand context, co-design solutions, and lead technical teams through product development. In this role, you will lead architecture work on client programmes. You will design and oversee end-to-end technology solutions that are scalable, secure, user‐centred, and ethically responsible. This role involves translating business needs into technology solutions, creating architecture artefacts, and supporting clients to make sustainable and user‐focused technology choices.

You might be a specialist in a particular technology domain or platform - such as legacy system migration, m365, Azure, GCP, AWS, data platforms or intelligent process automation - but you will apply a technology agnostic perspective. You'll operate as a trusted advisor, often leading smaller engagements or playing a senior role on larger ones, but may also work solo or contribute as a member of a team as needed. You will be the source of technical oversight and advice for the wider team and for the client. You will also support the development of junior colleagues while contributing to practice improvement and business development.
