Senior Software Engineer (Scala) - Supply and Demand Team

Job Description

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!

Team Mission

The 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 Wolt operations, as well as creating ways to dynamically influence the supply and demand.

Role Responsibilities

As a backend engineer, you will have a chance to work on topics around courier engagement and activation bonuses. 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.

Team Composition

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). Since the team also works closely with Data Scientists, this is a great chance to learn a lot about data science if you have a knack for it!

Location

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.

Our Expectations

• You have solid experience designing, building, and integrating quality software (microservices) in Scala on a large scale within a complex domain with a strong focus on an event-driven approach where decisions need to be made in an online manner.
• You have knowledge of AWS, Kubernetes, Docker, observability (Data Dog or similar tools), and data storages, both SQL and NoSQL databases. We are actively using multiple solutions: PostgreSQL, DynamoDB, MongoDB, Redis.
• You’re a dedicated person who is pragmatic with a positive attitude, who doesn't shy away from going outside of their comfort zone, and demonstrates curiosity and willingness to keep continuously learning.
• You’re comfortable working with real-world data and its different nuances.

Why Join Us?

• Our product organization consists of a team of over 800 people at Wolt. We aim to build none other than the best-in-the-world engineering team here.
• You’ll get to work in a company culture where we take ownership beyond the obvious, do common things uncommonly well, think big but stay humble, do right by people, treat others kindly and justly, recognize that if we don’t learn, we won’t stay still but fall behind, and keep in mind that Luke was Yoda’s greatest achievement.
• Join us for an exciting journey! The compensation will be a negotiable combination of monthly pay and DoorDash equity. The latter makes it exceptionally easy to be excited about our company growing and doing well, as you’ll own a piece of the pie.
