We are making travel effortless. Join us.

Whether it’s to visit the people closest to us, starting an exciting adventure, or a career-defining business trip, travel is an essential part of our lives. Yet we've all experienced the aches and pains of getting to our destination. Today, more than 4 billion airline passengers rely on technology that hasn't kept up with the expectations of the modern connected traveller.

That’s why we’ve started to rebuild the infrastructure that underpins the travel industry. We’re on a mission to unravel travel — simplifying systems and building the tools that will make the future of travel effortless.

We were part of Y Combinator S18's cohort and we are 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.

Overview

If you have a passion for helping customers and solving challenging technical problems then this may be the role for you. Duffel is hiring a Customer Success Engineer (CSE) to provide expert technical support to our largest and most important customers. You will help our customers by addressing their current questions and suggesting ways to use our APIs to build the best travel experience for their users. Additionally, you will collaborate with a cross-functional group across Duffel including Product, Engineering, Finance, and Travel Operations to ensure a superior customer experience with both the product and the company as a whole.
