Overview

Duffel is rebuilding 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. Central to this mission is ensuring seamless, secure, and reliable payment experiences, which are crucial for every transaction and a cornerstone of trust in our platform.

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

Payments at Duffel

The Payments team are looking after all of the core infrastructure that powers any kind of financial transactions on the Duffel platform. This ranges from cash-based systems to settle and reconcile transactions with suppliers distributed globally, to our card processing infrastructure, to commission tracking and payout system. Our goal is to build primitives that can be leveraged by the various vertical teams at Duffel (Flights, Stays, soon Cars) so they can focus on delivering seamless customer experiences.

What You’ll Do

• Designing resilient and scalable systems for reconciliation, reporting, and financial operations
• Integrating a variety of global payment gateways and VCC issuers
• Implementing best-in-class security practices for our tokenisation proxy and PCI environment
• Evolving our fraud detection and prevention systems

What We're Looking For In You

• A passion for designing and building fantastic APIs, delivering great developer experiences to go with it
• An interest in working with Elixir; this is what we mostly work with. Previous experience isn't necessary, and learning on the job is absolutely fine. What's more important is your general engineering ability rather than your knowledge of a particular language or framework
• A high bar in code quality and API design
• Opinions on what good engineering standards and processes look like as we define ours at Duffel
• Big-picture thinking – you can make trade-offs on technical work streams against business impact
• Fantastic communication skills. You're able to articulate what you're working on and why to the team in a clear and structured way
• You thrive in a collaborative environment. You believe in your own methods but keep an open mind, taking suggestions and feedback onboard as well

Bonus points if you have

• Experience working with payment systems, payment gateways (e.g., Stripe, Adyen, Braintree), or fintech platforms
• A strong understanding of payment security principles, compliance standards (like PCI DSS), or fraud management
• Experience in travel, flights, hotels, or cars

What You Can Expect From Us

We're dedicated to your personal growth. Our environment is comfortable both physically and in that our ears are always open to any ideas, concerns, and questions.
