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