Software Engineering Tech Lead – Node.js, React & TypeScript

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 ✨

Are you a hands-on engineering leader who enjoys solving complex technical challenges, shaping architecture and helping developers do their best work?

At IAG Loyalty, we're looking for a Tech Lead to help shape the future of our customer contact technology, building scalable, cloud-native solutions that connect our customers, colleagues and digital products.

This is an opportunity to take real ownership of technical design and delivery. You'll be making architectural decisions, getting hands-on with code and guiding engineers to build secure, reliable and high-performing solutions that make a genuine difference to how we support millions of Avios customers.

Working with technologies including Node.js, React, TypeScript and AWS, you'll help evolve our technology, tackle complex integrations and introduce new capabilities that improve both the customer and colleague experience. You'll have the freedom to challenge existing approaches, influence technical direction and drive engineering best practices.

Our customer contact technology includes Amazon Connect, alongside integrations with our wider Loyalty Platform, web and mobile channels. You don't need contact centre or Amazon Connect experience to succeed here. We're much more interested in your software engineering background, architectural thinking and ability to lead technical delivery.

What you'll be doing 🚀

As our Tech Lead, you'll be the technical driving force behind our Customer Contact products, combining hands-on software engineering with architectural ownership and technical leadership.

You'll design, build and evolve scalable, cloud-native applications and services using modern technologies including Node.js, React, TypeScript and AWS. Working closely with our Product Manager, you'll translate product ambitions into practical technical solutions, making architectural decisions that balance customer needs, security, performance and long-term maintainability.

You'll take ownership of complex technical challenges, from designing APIs and integration patterns to connecting our customer contact technology with the wider Loyalty Platform, web and mobile applications, and third-party systems. You'll help evolve our existing capabilities and shape new solutions that improve efficiency, reliability and the overall customer and colleague experience.

Remaining close to the code, you'll contribute to development, review technical solutions and champion high engineering standards. You'll help improve testing practices, CI/CD pipelines and system performance, ensuring the technology we build is secure, maintainable and ready to scale.

Beyond hands-on delivery, you'll guide and mentor engineers, share knowledge and encourage fresh thinking across the team. Working collaboratively with Product Managers, architects and engineering teams across IAG Loyalty and the wider group, you'll help shape technical direction, challenge existing approaches and continuously improve how we design and deliver software.

What you'll bring ⚡

We're looking for someone with a strong software engineering background who enjoys being hands-on, solving complex problems and taking ownership of technical decisions.

• Software engineering expertise – strong hands-on experience designing, developing and delivering modern applications, ideally using Node.js, React and TypeScript, with a solid understanding of frontend and backend development, APIs and software design patterns.
• Architecture and technical design – experience designing scalable services, APIs and distributed systems, with the ability to evaluate technical options, make sound architectural decisions and consider long-term maintainability.
• Cloud and DevOps experience – practical experience building and operating cloud-native applications, ideally within AWS, alongside an understanding of CI/CD, infrastructure as code and modern development practices. Experience with GitHub and Terraform would be advantageous.
• Integration and security – a solid understanding of API design, system integration patterns and security principles, with experience connecting services and third-party platforms.
• Technical leadership – experience guiding engineers, reviewing code, sharing best practices and raising engineering standards. You don't necessarily need to have held a formal Tech Lead title.
• Collaboration and delivery – the ability to work closely with Product Managers, engineers and wider stakeholders, translating business challenges into technical solutions and delivering value in an agile environment.

Experience with Amazon Connect or contact centre technology would be a bonus, but it's not essential. We're open to engineers from different industries who bring strong engineering fundamentals, architectural thinking and a passion for building great products.

We might not be right for you if:

• You only want to focus on your to-do list; we’re a small, high-performing team, we help each other to succeed.
• You value perfection over fast iteration and progress; IAG Loyalty moves fast, we learn and iterate as we go; our environment isn’t right for everyone.
• You’re looking to create but not build; this is an end-to-end role, you need to be comfortable owning your space, from ideation through to delivery and review.

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.

The Blend 📍

This role will work as part of our Loyalty Division and 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
