Principal Solution Architect

Overview

Join to apply for the Principal Solution Architect role at TPXimpact | B Corp

We’re growing our team! We’re looking for Principal Solution Architects who will serve as key leaders on client-facing projects. This role involves guiding clients and development teams through complex digital product development and technology implementations. You will work closely with clients and internal teams to understand context, co-design solutions, and lead technical teams through product development.

You will be accountable for running projects, leading architecture work across some of our most complex and high-impact 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 artifacts, 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.

Your work will be human-centred, design-led, and agile. As a principal consultant, you will lead projects 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.

The Principal Solution Architect will also drive the growth of the Technology Strategy and Architecture practice, contribute to business development, and mentor other consultants and architects.

We are committed to having a positive impact on the clients and the communities we serve. We actively encourage applications from women, disabled, Black, Asian, and Minority Ethnic candidates and historically under-represented groups.
