Software Engineer

At the fast growing scale of the Wolt business our operational efficiency benefits greatly from having automation for managing supply (how many courier partners are online) and demand (how many orders are being placed by customers). For us it’s a clear win-win situation, but it takes an entire team to make sure that this is possible. 💪 So, in order to achieve our mission to build the best tools for keeping the fine balance between supply and demand of delivery services at any given time and place, we’ve come to the point where we decided to strengthen our ranks by adding one more Backend Engineer to our new Supply and Demand team to balance out our own team needs!

Supply and Demand team’s mission is to make Wolt cities efficient for our customers, merchants and couriers, as well as making running the cities smooth for our operations people. This is done by building tools and features that help achieve balance between supply (number of Courier Partners online) and demand (home delivery orders from consumers) by surfacing the forecasts to both our Courier Partners on the Courier App and and Wolt operations, as well as creating ways to dynamically influence the supply and demand. As a backed engineer you will have a chance to work on topics around courier engagement and activation bonuses. That can be fun and rewarding for several reasons:

• This field encourages innovative approaches and experimentation. You can try out new technologies, frameworks, and methodologies to see what works best.
• You often collaborate with various teams such as data science, product management, and operations.
• Designing systems to optimize courier activation and bonuses involves solving complex logistical and algorithmic problems.
• The need for real-time solutions means you often work in a fast-paced, dynamic environment.

At the moment, the team consists of two frontend developers, several backend engineers and data scientists as well as the engineering team lead and product lead. The main programming languages on the team are Python, Scala, and Typescript (React) and since the team also works closely with Data Scientists so this is a great chance to learn a lot about data science if you have a knack for it!

Lastly, this role can be based in one of our tech hubs in Helsinki, Stockholm, or Berlin or you can work remotely anywhere in Finland, Sweden, Germany, or Estonia. Read more about our remote setup here.
