Domain Architect - Operational Procurement (gn)

We’re on the lookout for a talented Domain Architect (gn) to help us transform our Operational Procurement architecture into a modern, scalable, and streamlined system. In this role, you’ll guide multiple teams, making sure we’re all on the same page and working together to evolve legacy systems into clean, decoupled components using best practices. You’ll serve as an important link between Platform Managers, Director of Engineering, Delivery Lead, development teams, and the Chief Software Architect, mentoring engineers and fostering cross-team collaboration.
The Challenge: As our Operational Procurement Domain has grown, so have its complexities - like defining clear boundaries for teams and domains, managing separation of concerns, building new components, and untangling legacy systems. Your mission? Help our organisation bring structure and clarity to these areas so we can build a future-ready architecture that sparks innovation and supports business growth.
This is a great opportunity to shape a smarter, cleaner Operational Procurement domain - where creativity thrives, and business success follows.
