Kotlin Backend Engineer - Retail Group

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.

As a Software Engineer in Global Retail,

you'll shape how customers discover, browse, and buy retail products - apparel, beauty, electronics, auto parts and more - across

Wolt, DoorDash and Deliveroo. Retail is a large growth opportunity for the business, and our mission is to be the most trusted and

magical way to shop the brands and local stores customers love. You'll play a key role in making that real - from product

discovery through to shopping experience in the apps millions of people use every day.

You’ll join an evolving area where

we are replacing and improving parts of the existing consumer apps, building specific retail journeys within large-scale B2C

applications. This means working in a complex environment where multiple teams own different parts of the same app, and where

strong technical judgment is needed to create consistency, quality and speed across teams.

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.

As an engineer in our group, you’ll work on production-level microservices in Kotlin

and Go, 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.

Our

Tech Stack​

Our core technologies include Kotlin (Ktor, Koin, Spring, gRPC), PostgreSQL, MongoDB, Kafka, Redis,

GitHub Actions, AWS, Docker, and Kubernetes.

Wolt is a place where you can learn,

teach, and grow. If you’re passionate about building great technology and working in an environment that values teamwork and

autonomy, we’d love to hear from you!

📍These open roles are based in our tech hubs in Helsinki. We work in distributed

teams, but might not be able to offer fully remote work or relocation.

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. As we are exploring Go, we're looking for people who are

confident in their ability to learn and teach! 🛠️

Beyond technical expertise, we value ownership, collaboration, and a

mindset for growth. We think you're a great communicator who thrives in tackling complex challenges, questioning conventions, and

working closely with teammates to build reliable, scalable systems. 🚀

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!

Our Commitment to Diversity and

Inclusion​

We’re committed to growing and empowering a more inclusive community within

our company, industry, and cities. That’s why we hire and cultivate diverse teams of people from all backgrounds, experiences, and

perspectives. We believe that true innovation happens when everyone has room at the table and the tools, resources, and

opportunity to excel.
