## Description

SENIOR 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 a Senior Engineer to help shape both the product and the team building it.



ENGINEERING AT DUFFEL

We're building tools to simplify travel distribution, search, and booking through one seamless API. The technical challenge? Design a world class API, then integrate it with a vast number 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.

As a Senior Engineer, you won't just execute against a spec - you'll help define what gets built and how. You'll take on ambiguous problems, shape technical decision
