About Us
We are part of International Airlines Group (IAG), one of the world’s leading airline groups and owner of some of the biggest brands in the sky.

Purpose of the role
Unlike domain or product specific architecture roles, this position is explicitly generalist in scope, operating horizontally across platforms, products and operating companies, and focusing on how architecture collectively enables strategic outcomes.
This role operates as part of the OpCo architecture function, accountable for local architecture outcomes and decision‑making. While aligned to Group Enterprise Architecture strategy, policies and principles, the role retains autonomy to shape and govern OpCo architectural solutions that best meet local business, delivery and regulatory needs.
