Full job description

Software Engineer London | Full-time | Hybrid | Shoreditch/Liverpool Street

Create the Future of Travel With Us

Whether it's visiting the people closest to us, starting an exciting adventure, or a career-defining business trip, travel is essential. Yet we've all experienced the aches and pains of getting to our destination.

More than 4 billion airline passengers rely on technology that hasn't kept up with modern expectations. That's why we're rebuilding the infrastructure that underpins the travel industry - simplifying systems and building tools that will make the future of travel effortless.

We were part of Y Combinator S18's cohort and we're backed by Benchmark, Blossom, Index Ventures, and Kima Ventures - a fantastic set of investors that has helped build some of the world's largest companies.

Our London team is growing, and we're looking for talented people to join us on our journey.

Engineering at Duffel

We're building tools to simplify travel distribution, search, and booking through one seamless API. The technical challenge? Design a beautiful API, then integrate it with hundreds of travel providers - each with different systems and requirements - whilst delivering a fantastic developer experience.

We work with Elixir, Phoenix, Kubernetes, and Google Cloud Platform, but we value strong engineering fundamentals over specific tech experience.

You'll Thrive Here If:

You're passionate about designing beautiful APIs and creating great developer experiences

You have a high bar for code quality and API design

You have opinions on good engineering standards and processes as we define ours at Duffel

You think big picture - making tradeoffs between technical work and business impact

You communicate clearly, articulating what you're working on and why in a structured way

You thrive collaboratively - you believe in your methods but stay open to feedback and suggestions

Bonus: Experience in travel, flights, hotels, or cars

What You'll Get:

Competitive salary + equity (you'll own part of Duffel)

Work from anywhere policy

Duffel travel allowance (use what we build)

Matched parental leave

Sabbatical programme (3 months full pay)

Visa sponsorship available

Office in Shoreditch + regular team socials

Why Now Matters

You'll work on the core API powering millions of travel bookings. Early-stage role = outsized impact on how we build and scale.
