R&D Finance Developer, Oldebroek

Travelier

is a global leader in ground transportation, offering bus, train, and ferry tickets from thousands of suppliers through our five consumer websites: Bookaway, 12go, Plataforma 10, Deonibus, and Traveling.com. Following a period of rapid growth and acquisitions, we are consolidating our technology to power the next stage of our journey.

The Travelier Connect team is at the heart of this transformation. We are a group building the single, unified tech platform that will scale all of Travelier's growing B2C activity and unlock new revenue streams. Our mission is to build a scalable, modern solution that enables faster innovation and growth across the entire company.

About The Role We are looking for a talented developer to join our R&D Finance team, where the stakes are real and the work genuinely matters. You'll be building and owning the financial systems that power our business - from core payment infrastructure to complex accounting system design - working at the intersection of engineering excellence and mission critical systems that must work in scale.

You'll take full ownership of meaningful, complex challenges - from integrating with global payment providers and PSPs to designing the internal logic that moves money reliably and traceably.

You'll shape financial processors, build reconciliation flows, and develop the dashboards that give our finance teams real clarity and control. Your decisions will directly influence how the business operates and scales.

Beyond the code, you'll be a key voice on the team - contributing ideas, challenging assumptions, and helping shape what gets built and why.
