This is a hybrid role based in the UK, offering the opportunity to shape the future of the AdTech ecosystem.

• Provide architectural input for build vs buy decisions across multiple initiatives.
• Deliver artefacts in agreed formats (eg, Confluence documentation, architecture diagrams, technical papers).

What We're Looking For

• Proven experience in enterprise architecture and solution design within complex, multi-system environments.
• Strong understanding of integration patterns, data architecture, and platform strategy.
• Ability to document current-state and define future-state architectures.
• Experience supporting vendor evaluation and build vs buy analysis.
• Excellent stakeholder engagement and communication skills.
