This job is no longer accepting applications.

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.

Our humble expectations

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.

Next steps

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.

If you want to check up on your application or have any further questions about the position you can turn to Talent Acquisition Partner, Severi Kausola, at at any given time.

We’re currently active in 23 countries and more than 100 cities, servicing over 7 million customers. Our apps (iOS and Android) have the industry’s highest reviews, largely because of our customer-centric approach to how we build our products and operations. For example, our customer service team responds in a matter of seconds, in the customer’s own language.

We've also been fortunate enough to receive some appreciation and recognition for our hard work along the way: Apple selected Wolt’s app as their Editors' Choice, Wired named the company one of the "Hottest Startups in Europe," Forbes included our CEO Miki Kuusi on its 30-under-30 in Consumer Tech list, and the Nordic Startup Awards named Wolt Company of the Year. In 2020 we were recognized as Europe’s most promising startup as part of Adyen and TNW‘s #Tech5 competition, and as the fastest growing tech company in Europe by the Financial Times.
