Who we are


We’re IAG Loyalty – one organisation with two ambitious, growing divisions across Loyalty and Holidays. Each has its own goals, strategy and team, but together we’re united by a shared vision to create a more rewarding world of travel and experiences.


Our Loyalty division is home to Avios, the global loyalty currency, enabling millions of members to collect and spend rewards across travel, retail and financial services.


Our Holidays division including British Airways Holidays and Iberia Vacaciones, brings together trusted brands, connecting customers to thousands of destinations worldwide through seamless, end‑to‑end travel experiences.


We’re on an exciting journey of growth and transformation – we’re going places.



The Opportunity ✨


As the Loyalty division evolves into a Platform as a Service business, we’re looking for a talented and passionate Senior Application Security Engineer to join our security engineering team. You’ll have a background in software engineering and a deep interest in application and API security. You thrive on collaboration, enjoy helping others grow, and see security as an enabler — not a blocker. You’ll be an AppSec advocate who supports our engineers in identifying and addressing security issues across the software development lifecycle.


You’ll be part of a small, dynamic team within the Product department that drives the Loyalty divisions digital transformation, technology strategy, and product direction. Our cloud‑native platform powers the Avios currency and the digital experiences used by millions of loyalty members. This is a great opportunity to work with cutting‑edge technology in a fast‑paced, agile environment.
