Senior Application Security EngineerWho we are 🩵
We're the people behind the global loyalty currency, Avios, and home to three ambitious, growing businesses; IAG Loyalty, British Airways Holidays and The Wine Flyer . Each business has its own goals and strategy, but collectively we create brilliant experiences for our global customers.
We're on a truly exciting journey of growth and transformation - we're going places! This is where you come in.
The Opportunity
As IAG Loyalty 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 IAG Loyalty's 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.
This role is based out of our London office. We call our approach to hybrid working The Blend - it's about giving you the flexibility to choose where you do your best work, while staying connected with your team and the wider business. This means you will be required to spend at least two days per week in the office, with the rest of the time working from home. You may also be required to work from one of our other office or partner locations, based on your role and 'to do' list.
What you'll be doing 🌠
As a Senior Application Security Engineer, you'll lead the application security practice within the IAG Loyalty security team, taking responsibility for key security KPIs in this area. You'll champion secure software development by working closely with engineers and product teams, embedding security practices into our engineering culture. You'll provide training, offer expert advice, and drive awareness of security from the earliest stages of design through to deployment.
You'll help integrate automated security tooling and checks into our CI/CD pipelines, facilitate threat modelling sessions, and review security-sensitive design decisions around authentication, cryptography, and logging. You'll also ensure that tools such as SAST, DAST, and SCA are effective and efficient, and that testing programmes - including pen testing, vulnerability scanning, and bug bounty - are delivering value.
You'll triage vulnerabilities, support engineering teams with practical mitigations, and contribute to documentation that strengthens our internal standards and processes. Maintaining a strong security culture will be a key focus, and you'll also support internal and external audits where needed.
