In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the globe.

Working at Wolt isn’t always easy, but it’s definitely exciting. Here you’ll learn more, build more, and ship more than in most other companies. You’ll be challenged a lot, but also have a lot of fun on the way. So, if you’re a self-starter with drive and entrepreneurial spirit, this could be the ride of your life.

We’re hiring a Senior Backend Engineer to join our Merchant Data Hub team - a group on a mission to redefine how merchant data powers Wolt’s platform. We’re looking for someone who thrives in complex technical environments and enjoys the autonomy of building systems from the ground up.

The Merchant Data Hub team builds and owns the core systems responsible for indexing and serving merchant data across Wolt.

This distributed team of backend engineers and a team lead based across Helsinki and Berlin.

The team is currently rebuilding the foundations of Wolt’s merchant data flows to support future use cases across multiple markets.

This is a greenfield opportunity to design and build large-scale distributed systems that directly impact millions of users worldwide. As part of this team, you’ll have high ownership, visible impact, and the freedom to make key architectural and product decisions.
