Luton | Full-time | Hybrid

We support hybrid working, and you’ll spend 60% of your time each month in the office.

You’re a highly capable software engineer who enjoys solving complex technical problems and building high-quality software that operates at scale.

You combine strong hands‑on engineering with sound technical judgement, a collaborative mindset and a genuine sense of ownership. If you're passionate about creating reliable, maintainable solutions while helping shape technical direction through expertise and example, this role offers the opportunity to make a meaningful impact across one of Europe's leading travel brands.

The opportunity

As a Senior Software Engineer, you'll play a key role in designing, building and operating the technology that supports millions of customer journeys every year.

Working as a senior individual contributor within a product-focused engineering squad, you'll spend most of your time hands‑on, developing software, solving complex technical challenges and improving the reliability, scalability and performance of our systems.

You'll help guide technical decisions, contribute to architecture discussions and collaborate closely with engineers, product managers and stakeholders to deliver solutions that create value for customers and the business.

"The best Senior Engineers combine deep technical expertise with a practical approach to delivery. They lead through example, help others succeed and consistently raise the quality of both our software and our engineering practices." Head of Software Engineering

You'll design, build, test, deploy and support production software, taking ownership of significant technical challenges and delivering high-quality outcomes.

You'll contribute to technical design and architectural discussions, balancing speed, simplicity, maintainability and long-term sustainability when making engineering decisions.

You'll continuously improve systems through better testing, observability, performance optimisation and operational practices, helping ensure our platforms remain reliable and scalable.

You'll also:

• Write clean, maintainable and well‑tested code.
