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.

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.

What you’ll be doing

As an engineer in our group, you’ll work on production-level microservices in Kotlin, helping shape how merchants succeed with Wolt.

Day-to-day in this role you’ll:

• Design, build, and scale reliable systems that power merchant experiences.
• Work across the full development lifecycle – from business logic and testing to cloud infrastructure and data streaming.
• Collaborate on architecture and technology choices that keep our systems simple, scalable, and efficient.
• Grow your skills and knowledge by working alongside experienced teammates in an environment that values learning and experimentation.
  
  

Our core technologies include Kotlin (Ktor, Koin, Spring, gRPC), PostgreSQL, MongoDB, Kafka, Redis, GitHub Actions, AWS, Docker, and Kubernetes.

Our humble expectations

• We’re looking for a Software Engineer with practical hands-on experience to join the Merchant Group at Wolt! If you have a strong desire to learn, grow, build and maintain scalable, production-grade systems and want to drive impact at scale, this is the place for you.
• While Kotlin is our primary language, experience with Java, Scala, or other JVM backend languages is great - if you’re confident in your ability to learn and have a desire to grow fast, we’d love to hear from you!
• Beyond technical knowledge, we value ownership, collaboration, willingness to learn and a mindset for growth. You thrive in tackling complex challenges, questioning conventions, and working closely with teammates to build reliable, scalable systems. 🚀
  
  

What we offer

• Autonomy & Ownership – Our engineers have end-to-end responsibility for their services, from implementation to production.
• Collaboration – Architecture and ways of working are defined together, ensuring we make the best choices for long-term success.
• Scalability & Simplicity – We value pragmatic solutions that keep our systems robust without unnecessary complexity. We use technologies that serve Wolt, our teams, and our engineers best. You’ll have the freedom to experiment and adopt the tools that work.
