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. 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.

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.

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

- You are hands-on. You're comfortable jumping into the codebase, contributing directly to projects, and pairing with engineers to solve complex problems.

- You have strong technical judgment. You can arbitrate technical discussions and make tradeoffs that balance short-term impact and long-term health.

- You’ve led engineering teams. You’ve managed and grown mid-sized teams (5-10 engineers), and you know how to balance delivery with team wellbeing.

- You value leadership. You lead by example, create space for others to thrive, and measure your success through the growth and success of your team.

- You communicate with clarity. Whether in code reviews, design documents, or team updates, you communicate ideas in a way that builds shared understanding.

- You embrace autonomy. You can be trusted to drive initiatives forward without micromanagement, and you help others do the same.

- Technical leadership: Writing and reviewing production code regularly, contributing to Duffel’s engineering standards and helping the team make well-informed technical decisions.

- Shaping the roadmap: Collaborating with product managers and designers to define and deliver on a roadmap that balances technical and customer priorities.

- Team enablement: Driving high team performance through enabling healthy engineering practices—agile delivery, rapid iteration, test-driven development, and continuous improvement.

- Mentorship & coaching: Supporting your teammates in their personal growth through 1:1s, mentoring, and continuous feedback. Helping engineers identify and pursue their career goals.

- Engineering culture: Actively contributing to a positive, inclusive, and collaborative culture where technical excellence and empathetic leadership go hand in hand.

- Org design & hiring: Partnering with the People team and leadership to recruit, onboard, and retain top engineering talent. Helping shape how Duffel scales its technical organisation.

- Cross-functional collaboration: Working across teams to improve developer experience, infrastructure, reliability, and scalability of our systems.

We're dedicated to your personal growth. Our environment is comfortable both physically, but also in that our ears are always open to any ideas, concerns and questions. We believe that everyone should have pride in their work, taking full ownership of it and its impact. That's why everyone who joins Duffel owns a share of the company.
