About Wolt

At Wolt, we create technology that brings joy, simplicity and earnings to the neighborhoods of the world. In 2014 we started with delivery of restaurant food. Now we’re building the delivery of (almost) everything and you’ll find us in over 500 cities in 30 countries around the world. In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the globe.

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.

We are looking for Software Engineers who can develop production-level backend services in Python, to join several different Engineering Groups at Wolt. We have exciting opportunities for senior engineers ready for their next big adventure, as well as for engineers with a few years of experience looking to take the next step in their careers.

Our Engineering organization at Wolt consists of 700+ Engineers working across 70+ product teams. Some of us work on the visible parts, making our services easy on the eye and some of us focus on the unseen magic happening behind the scenes. 

Our Engineers handle the whole development process (business logic, testing, database & data streaming, CI/CD, analytics, cloud) in an autonomous manner. They build things that are accessible and made to scale. They keep our systems in the best shape by simplifying the unnecessary complexity.

We make the decisions as a team and group of teams for our ways of working and we take architectural decisions together. Everyone plays a role in our future.

Our Engineers choose the best technologies that work for Wolt, their teams and themselves. Making good choices means finding scalable, robust technology that works in everyone’s best interests. The freedom to experiment and adopt the best technology benefits everyone. Needless to say, in such an environment there’s a lot of room for learning, teaching and growing together! 

The main stack for these roles consists for example Python (FastAPI), PostgreSQL, MongoDB, Kafka, Redis, GitHub Actions, AWS, Docker and Kubernetes.

At the moment, we’re particularly looking to hire for the following groups:

Courier Group: The Courier Group is made up of great teams dedicated to optimizing logistics and routing, enhancing courier partner earnings, forecasting, and delivering outstanding onboarding and delivery experiences for our courier partners.

We are currently hiring for both the Supply and Demand team and the Fulfillment team. The Supply and Demand team's goal is to establish cities that are operationally efficient and convenient for courier partners, restaurants, and customers. We ensure we connect our courier partners when and where our consumers need them. Our team is currently focused around two main topics, courier partner monetary solicitation strategies and dynamic arrangement of delivery areas in the cities. We have an opportunity to serve millions of requests towards courier partners and apply decisions based on the state in an online manner.

The fulfillment team’s goal is to make our logistics platform more efficient while improving on-going delivery experience for consumers. To improve logistics efficiency the team is continuously making efforts to produce accurate travel and other fulfillment estimates of the delivery. This is achieved through building our own Maps platform and using Machine learning models to improve the accuracy constantly. While the on-going delivery experience is enhanced through more realistic & stable delivery ETA.

Data Group: As the scale of Wolt has rapidly grown, we are introducing new users to our data platform every day and want this to become a coherent and streamlined experience for all users, whether they’re Analysts, Data Scientists working with our data or teams bringing new data to the platform from their applications. We aim to both provide new platform capabilities across batch, streaming, orchestration and data integration to serve our user’s needs, as well as building an intuitive interface for them to solve their use cases without having to learn the details of the underlying tools.Our primary programming language of choice is Python. We deploy our systems in Kubernetes and AWS. We use Datadog for observability (logging and metrics). We have built our data warehouse on top of Snowflake and orchestrate our batch processes with Airflow and Dagster. We are heavy users of Kafka and Kafka Connect. Our CI/CD pipelines rely on GitHub actions and Argo Workflows. 

For Data Group, we have open roles to multiple teams for engineers based either in Helsinki or Berlin.

Merchant Group: The Merchant Group consists of 150+ engineers across 25+ cross-functional teams, working together to help merchants grow their businesses and streamline operations through innovative technology. Some of us focus on building seamless experiences for our merchants, while others work on the behind-the-scenes magic that makes everything run smoothly.

Currently, we are especially hiring for Wolt at Work and Drive Core teams. Wolt at Work team builds services for Wolt's business customers, making ordering and expensing easy for them and allowing them to give benefits to their employees. We build both consumer facing features, admin portal for the company account management and handle the payments, invoicing and reporting processes for the company payments.

Drive Core is a suite of products that enable our partners to use the courier partner fleet of Wolt for their own deliveries. Drive as a product is a rising star within Wolt with a lot of potential in the future. Due to the nature of the B2B domain, working in this role means facing new challenges continuously, which sometimes requires a lot of creativity. Drive works directly with purchase flow, hence working at Drive also means that you will have the opportunity to expand your knowledge across almost all important aspects of the Wolt system, e.g. merchant, venue, corporate service, logistics, etc. We also have a great team culture, where all of the engineers are fully trusted and given a lot of freedom when it comes to decision making and taking ownership.

📍All these roles are open for candidates who are based in Finland but some of the teams are also open to hiring for Tallinn, Berlin or Stockholm. Thus if you are based either in Finland or Tallinn, Berlin or Stockholm, don’t hesitate to apply.  We offer a flexible hybrid setup: you can choose to work from the office, remotely, or a mix of both - whatever suits you best. We also offer relocation support if interested in relocating to Helsinki from another country. 

Our humble expectations

We are looking for Software Engineers who can develop production-level microservices in Python. We'd love to see experience with building high-load and large-scale systems in Python. We have openings for both senior engineers with extensive experience and engineers with a few years of experience.

As a member of our teams, you'll dive into the world of microservices, primarily using Python, while remaining open to exploring other modern languages, such as Kotlin and Go, in some teams. We appreciate previous experience in handling the whole development cycle all the way to production.

But what truly sets you apart is your ability to tackle big challenges together, envision scalability and availability, and dare to question conventional decisions. You’ll be successful in our teams if you quickly grasp new concepts and thrive in an environment of continuous learning. 

We put a lot of focus on the ability to collaborate well with others. We work closely with our teammates and having a good connection with team members is essential. We understand that everyone has their own unique way of communicating with others. We expect you to be yourself, express your opinions, and work together with the rest of the team.

In addition to technical expertise, we cherish those who take ownership beyond the obvious, have an insatiable hunger for knowledge, make collaborative decisions, and enthusiastically collaborate with diverse teams Woltwide. We value the unique perspectives and skills you bring to our adventure, and we're excited to see what you can achieve with us!👥🚀

Next steps

We are hiring for a number of positions across a few different Engineering Groups. During the initial screening call our Talent Acquisition Partner will discuss with you your expectations and possible domain preferences as well as share more about different teams. After the call with a Talent Acquisition partner, the interviewing steps are conducted for a particular group in mind, with a specific team being proposed at the end of the process - that’s the moment when you’ll latest get to meet your possible Team Lead. Throughout the process, we will do our best to match your experience, skills and aspirations with the most suitable Engineering team at Wolt!
