Full-time
We’re looking for experienced Software Engineers to join various teams within the Merchant Group at Wolt! If you have a strong track record of building and maintaining scalable, production-grade systems and want to drive impact at scale, this is the place for you.
Who We Are
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 Do
As an engineer in our group, you’ll work on production-level microservices in Kotlin, helping shape how merchants succeed with Wolt. You’ll have opportunities to:
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.
How We Work
Autonomy & Ownership – Our engineers have end-to-end responsibility for their services, from implementation to production.
Collaboration – Architecture and working methods 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.

📍These open roles can be based in our tech hubs in Helsinki, Stockholm and Tallinn. You can choose whether you want to work from home, from the office or hybrid.
Our humble expectations
We’re seeking experienced Software Engineers with a strong background in building scalable microservices. 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, we’d love to hear from you! 🛠️
Beyond technical expertise, we value ownership, collaboration, and a mindset for growth. You thrive in tackling complex challenges, questioning conventions, and working closely with teammates to build reliable, scalable systems. 🚀
Next steps
We are hiring for multiple open positions across different teams in the Merchant Group. 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 the group. After the recruiter screening call, during the rest of the interviewing steps, you’ll meet hiring managers and software engineers from the Merchant group, a specific team being proposed at the end of the process - that’s the moment when you’ll 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!
The compensation will be a negotiable combination of monthly pay and DoorDash RSUs. 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.
