  • 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.

  • ✅ 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)

  • 🧘‍♂️ Sabbatical programme (3 months full pay)
