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.

Engineering Excellence: You’re skilled in writing production-level code and following engineering best practices, ensuring your solutions are efficient, maintainable, and scalable.
Clear Communication and Drive: You can effectively communicate complex technical concepts to non-technical audiences, bridging the gap between data science and business needs. You can take ownership of initiatives and drive projects to conclusion while working with varied stakeholders.
Analytical Problem-Solving: You excel at breaking down complex business challenges into clear, solvable machine learning problems, and designing data-driven solutions to address them.
If you’re driven to make an impact through innovative machine learning solutions, we’d love to see how you can help us push boundaries!
