## About the Role

The headline: We're looking for a Solution Architect with 1-2 years of architecture experience, built on a solid software engineering background. Someone who's been a developer, understands how systems behave in production, and can turn that into pragmatic, scalable architectural decisions.

Retail domain experience is essential: you'll be shaping solutions that directly impact store operations, digital commerce, supply chain, and customer experience., * 2:1 or above degree in Computer Science or a STEM discipline.

 * 1-2 years of Solution Architecture experience in a commercial environment.
 * Strong engineering background: ideally 4-6+ years as a hands-on developer.
 * Retail domain experience (eCommerce, POS, supply chain, merchandising, store systems, or similar).
 * Solid understanding of modern architectures: APIs, microservices, event-driven patterns, cloud platforms, CI/CD, DevOps.
 * Ability to work in agile squads and collaborate with engineers, BAs, and product teams.
 * Clear communication skills: you simplify complexity and influence decisions.

Why this role matters:

You won't be stuck producing theoretical diagrams. You'll be embedded in delivery squads, shaping real solutions, working with engineers who value architectural clarity, and helping global retail organisations modernise its technology landscape.

This is a perfect fit if you're an ex-developer who wants to grow into a senior architect and build a career on top of genuine engineering credibility.
