Job Description

Wolt is looking for a Scala Developer to join our Logistics team. This is one of those parts of Wolt's business, people don't always realize the complexity of. Logistics is absolutely integral to Wolt, and doing it well can mean the difference between delivering blissful customer experiences efficiently and profitably vs. operational nightmare and a cacophony of late deliveries. Our routing platform is fully automated, with our proprietary route optimization system finding the optimal route for each courier partner, hopping between restaurants and customers. 

The Logistics team works on several backend service components for route optimization, traffic flow prediction, delivery time prediction and supply/demand control. Scala and C++ are used in the backend services whereas data analysis and machine learning is in Python. The team is a mix of developers, data scientists and optimization researchers.


As a Scala Developer in the Logistics team, you are responsible for making our logistics scale with the insane growth phase and to connect hungry people and hard-working couriers in global cities of millions e.g. Tokyo & Berlin. In the end, the challenges are related to questions such as how to simply divide the data into so small pieces that normal databases can handle it. So you need to be a fearless problem solver as Gyro Gearloose with experience of writing production level Scala. This far, the team has mostly used Akka, Play & Slick but there’s also Http4s and Typelevel.scala being used in newer projects.

Additional Information

The position will be filled as soon as we find the right person, so make sure to apply as soon as you realize you really, really want to join us!

The compensation will be a negotiable combination of monthly pay and Wolt stock options. The latter make it exceptionally easy to be excited about our company growing and doing well, as you'll own a piece of the pie.
