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. IAG Transform provides creative and innovative solutions to drive sustainable transformation by delivering procurement and airline services, as well as group-wide systems across IAG. Each operating company benefits from the Transform centralised model, driving efficiencies, automation, and economies of scale.
Purpose of the Role
The Generalist Principal Architect is accountable for maintaining a holistic, enterprise-wide architectural view across business, application, information, integration, infrastructure, cloud, and service domains. The role acts as a technology-agnostic, vendor-neutral authority, providing independent, expert architectural leadership and assurance to ensure that technology change across the Group is coherent, scalable, secure, and aligned to business strategy.
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.
Your Responsibilities
Enterprise & Cross-Domain Architecture
- Maintain an end-to-end architectural view across business capability, applications, integrations, data, infrastructure, cloud, security, and service layers
- Ensure architectural coherence across domains, identifying and addressing duplication, fragmentation, or misalignment
- Operate as a senior architectural authority able to review, challenge, and arbitrate design decisions across multiple technology areas
Strategy, Change & Enablement
- Translate business and Group strategy into clear architectural principles, target states, and transition roadmaps
- Identify opportunities to simplify, modernise, or converge technology landscapes in support of business objectives
- Support major programmes and initiatives by ensuring architectural integrity from concept through delivery
