easyJet holidays — Hybrid (3 days a week in Luton office)

easyJet holidays is the UK’s fastest‑growing tour operator, on a mission to deliver brilliant holidays at unbeatable prices across more than 100 destinations. By combining easyJet’s unrivalled flight network with over 5,000 handpicked hotels and best‑in‑class technology, we’re redefining what great value package travel looks like.

Launched in 2019, we’ve already:

Become the UK’s fastest-growing, lowest‑cost travel business

Taken almost 2 million customers away in our latest full year

Delivered award‑winning sustainability initiatives

Expanded into Switzerland, Germany and France

And been named a Sunday Times Best Place to Work two years running

We’re ambitious. We move fast. And we’re building exceptional tech teams to shape the future of travel.

The Role: Principal Software Engineer

As a Principal Software Engineer, you’ll play a pivotal leadership role within our growing Development team — the group that builds and evolves all proprietary software powering easyJet holidays.

You’ll lead the technical direction of major, high-impact engineering initiatives, architect scalable and innovative solutions, mentor engineers across the function, and help shape our long-term technology strategy.

This is a role for a hands-on engineering leader who loves solving complex problems, thrives in a fast-paced environment, and wants to make a visible impact on products used by millions.

What You’ll Be Doing

Leading complex, multi-team software projects from concept to delivery

Designing and maintaining modern, scalable architectures

Setting engineering standards and championing best practices

Mentoring and developing engineers across the team

Owning critical solutions and ensuring high‑quality, resilient code

Working closely with Product, Design and stakeholders to translate ideas into technical reality

Driving innovation and contributing to long-term technology plans

What You’ll Bring

Technical expertise in:

.NET / .NET Core and Node

JavaScript frameworks such as React, Angular or jQuery

CMS platforms (Sitecore experience a bonus)

HTML, CSS and modern front-end practices

GIT, CI/CD tooling (e.g., TeamCity)

Cloud technologies (AWS preferred)

Agile delivery environments

TDD/BDD, multi‑level testing, high-transaction systems, and enterprise-scale engineering

Soft skills that set you apart:

Excellent communicator who builds strong relationships

Logical, analytical mindset with outstanding problem‑solving skills

A natural mentor who guides teams with clarity and empathy

Comfortable with ambiguity and able to navigate complexity with confidence

Why Join Us?

At easyJet holidays, you’ll work in a modern, dynamic environment where ideas move fast and your impact is felt immediately. You’ll also enjoy an exceptional benefits package, including:

Competitive base salary

Up to 20% bonus

25 days holiday

BAYE, SAYE & Performance share schemes

7% pension

Life assurance

Flexible benefits

Industry‑leading staff travel perks

Working Model

This is a hybrid role, with 3 days per week in our Luton office and flexibility on the remaining days. Some occasional travel may be required.

Ready to Join Us?

If you’re excited to build industry‑leading technology with one of the UK’s most ambitious travel brands, we’d love to hear from you.

Apply now and help shape the future of easyJet holidays.
