Working in Product Development at Wolt

At Wolt, we’re about getting things done. You’ll probably enjoy it here if you like taking ownership, developing yourself and being around friendly, humble and ambitious people. 

The behind the scenes of Wolt is run by an awesome bunch of over 700+ planners, builders, designers and data crunchers. We call ourselves Product+, as we’re the very core of Wolt’s products, tools and platforms. To build our products, we work in over 60 cross-functional, independent and autonomous teams. Teams are made up of a mix of talented individuals: engineers, designers, data scientists, analysts, and product leads. Each team takes ownership for solving customer problems in the best possible way.

Our Commitment to Diversity, Equity & Inclusion

We want to have all sorts of people in our team – people like you and me, and people different from you and me. To be able to work with diverse teammates – when it comes to gender, age, ethnicity, life background, sexual orientation, political views, religion, or any other personal trait – we consciously aim to offer equal opportunity for everyone to work with us. This is because we believe diverse teams make the most thought-through decisions and build things in the most inclusive way.

Job Description

We are looking for experienced Senior Software Engineers who can develop production-level microservices in Kotlin, to join several different Engineering Groups at Wolt.

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.

The main stack for these roles consists for example Kotlin (Ktor, Koin, Spring, grpc…), PostgreSQL, MongoDB, Kafka, Redis, GitHub Actions, AWS, Docker and Kubernetes.

Needless to say, in such an environment there’s a lot of room for learning, teaching and growing together!

FinTech Group: dedicated to shaping the future of financial services at Wolt. 🚀 Our Fintech teams play a critical role in enabling smooth and automated money flows for our customers, merchants, and courier partners as well as delivering financial products to them. To meet local requirements and provide the best financial solutions, our Fintech engineering teams are at the forefront of building integrations and automating financial processes for local country teams, supporting expansion in our existing markets and into new ones.

We currently have multiple roles in our Fintech Teams, and depending on your experience, we will make sure to find the right team for you if you love working with modern technologies like Kotlin, are always open to learning new things, find motivation in working with skilled and nice colleagues, and don't shy away from highly challenging engineering topics, you'll fit right in! 💡👩‍💻

Merchant Integrations: Running a restaurant or a store while fulfilling delivery orders is hard work that can be made easy with automation. This is where our integration platform comes in. We help our merchant partners automate the manual work with our API and integration offerings. Once a merchant has these integrations in place, their staff are free to do what they do best - service consumers without being bogged down by mundane, repetitive, and error prone manual processes. Through our API platform, we ensure that the experience for our partners is best in class, making it a breeze to work with Wolt. Be it orders going to POS (Point of Sale) systems automatically, venue management, item & inventory control, menu & catalog automation, our teams have our merchants covered!

Merchant Operations: In recent years, we started expanding our delivery offering to new verticals beyond restaurant deliveries, including grocery, pharmacy, merchandise, flowers, and apparel, all referred to as “Retail”. That meant quite many new services and technical improvements as use cases and flows are more complex than ever. Our Merchant Operations subgroup consists of 4 different teams full of smart engineers creating new solutions to enhance our operational abilities with Merchants. Here, we build merchant applications that help merchants run their day-to-day operations. We also build all the relevant tooling from Product Catalog to Offer Management systems to make sure we can capture the full assortment of the merchants in the easiest way possible.

Merchant Engagement: Engagement focuses on Acquiring more quality Merchants and reducing the time and effort it takes to onboard them so they can make their first sales on Wolt. The group also aims to make best-in-industry self-service experiences for onboarding & Imaging, a unified Merchant portal where you can get everything you need done, and insights dashboard to help maximize business performance

Retail Platforms (Wolt Market): Last year we took a leap forward with a dedicated product offering for Wolt Market - Retail Platforms. Wolt Market is a chain of dark grocery stores available on Wolt’s well known delivery platform. Wolt Market delivers groceries to our users within 30 minutes. We successfully built from scratch several teams of talented Engineers, Product Leads and Designers building internal tooling within the areas like warehousing, assortment, catalog and pricing.

Consumer Group: As the name Consumer Group implies, we are responsible for building and developing Wolt’s consumer-facing products. Our mission is to master the user experience while scaling up the platform to enable delivering a mall in your pocket. We’re humbled and proud to say our apps have the industry’s highest ratings in the App Store (4.8) and Google Play (4.6). We believe that a great user experience enables healthy top-line growth. We make sure our users find the right content from the platform and convert. We are here in the long term by retaining our customers and keeping them engaged. Currently, the Consumer Group is growing especially in the front of AdTech and Search functions making sure we succeed in the above-mentioned mission.

📍These open roles can be based in all of our tech hubs in Helsinki, Stockholm, or Berlin. This can vary depending on the exact team and their main location. You can choose whether you want to work from home, from the office or hybrid.

Qualifications

We are looking for experienced Senior Software Engineers who can develop production-level microservices in Kotlin. We'd love to see experience with Kotlin or any other JVM backend languages like Java and Scala but encourage you to convince us about your learning abilities if you come from a different background. 🛠️

As a member of our team, you'll dive into the world of microservices, primarily using Kotlin, while remaining open to exploring other modern languages, such as Python, 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!👥🚀
