Data Engineer

IAG Loyalty; London; Hybrid; GBP 40,000 - 80,000; Full time

Job description

Who we are ????

We're the people behind the global loyalty currency, Avios, and home to three ambitious, growing businesses; IAG Loyalty, BA 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

We're looking for a Data Engineer to join the Core Data team within the Redemption function at IAG Loyalty. At IAG Loyalty, data is central to everything we do-driving decisions, innovation, and impact across the business.

In this role, you'll join a product squad focused on building data solutions that power the Redemption space-how customers turn Avios points into meaningful rewards. Whether it's understanding booking behavior or improving the reward experience, your work will have a direct impact on our products and decision-making.

We've made great progress migrating from legacy systems to a modern data stack, and you'll help us continue that journey-building new platforms and evolving the tools we've already delivered.

Though we're a large business by revenue, our data team operates like a fast-moving scale-up. We're looking for someone who's curious, adaptable, and ready to challenge the status quo. If you're excited to make a real impact, we'd love to hear from you.

What you'll get up to

You'll work across the full data lifecycle-from analysis and design to development, testing, and ongoing support of our data products. You'll play a key role in enhancing our existing platforms and infrastructure, contributing to inner-source projects that help standardise and scale data capabilities across IAG Loyalty. You'll also build applications that unlock new ways to activate and leverage our data. Working within a small, focused team using Kanban principles, you'll deliver impactful, iterative data products, while also creating clear documentation and training materials to support end users and drive adoption of new solutions.

What we need from you

• Strong SQL development skills-experience with Snowflake is a big plus, and bonus points if you've worked with dbt or SQLMesh.
• A track record of designing and delivering complex, high-impact data solutions.
• Solid understanding of ELT processes and the technologies that enable them.
• Comfortable working with cloud infrastructure, particularly AWS.
• Experience using Infrastructure as Code at scale; we use Terraform to manage and standardise our environments.
• Proficiency in at least one data-focused programming language-ideally Python (our primary language), or Go for performance-critical tasks.
• Excellent communication and collaboration skills, with the ability to work effectively across both technical and non-technical teams.
• A proactive, improvement-driven mindset-always looking for smarter, better ways to work.
• Strong attention to detail and a deep commitment to quality in everything you deliver.

Work Environment

The role has a blended base, between our Central London office and home. We trust you to make the right decision about the type of work that is best done in each location. We expect you'll achieve a 50/50 split between the two and there may be times where you'll want to visit our other locations to tell their stories, too (fully reimbursed).

You might not be right for us if:

• You prefer to stick strictly to your own tasks-we're a small, high-performing team, and collaboration is key to our success.
• You prioritise perfection over progress-we move fast, learn as we go, and value iteration over polish.
• You want to create but not build-this is an end-to-end role, and you'll own your work from initial idea through to delivery and iteration.

If you think you have what it takes but don't meet every single point above, please do still apply. We'd love to chat and see if you could be a great fit.

Equity, Diversity and Inclusion at IAG Loyalty

Our vision, 'to create the world's most rewarding experiences,' applies not only to our customers but for our colleagues too. It's about taking belonging seriously, actively fostering a culture where everyone feels welcomed and valued by embracing diverse identities, personal histories, and perspectives.

This commitment makes IAG Loyalty a rewarding place to work and enhances our ability to solve complex problems, drive innovation, and better serve our customers and communities.

Please let us know if we can make any reasonable adjustments to support your interview process with us.
