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’re looking for passionate and product-minded Backend Engineers to join our Discovery team - the group behind some of the most visible and impactful parts of Wolt’s consumer app. You’ll work on features that help millions of users discover their next favorite restaurant, grocery store, or product- from the homepage and category views to new vertical experiences like groceries, electronics, pet food, and health & beauty.

This is more than just a backend engineering role. We’re looking for someone who combines strong technical skills with curiosity, ownership, and a deep interest in creating meaningful user experiences at scale.

What you’ll do:

  • Design, build, and operate high-performance backend services - primarily in Kotlin (experience with Python or especially with Go is a plus) -  powering discovery surfaces, front pages, and category experiences across Wolt’s new and existing verticals.
  • Own your services end-to-end: from requirements, design, and delivery to testing, CI/CD, deployment, monitoring, and on-call.
  • Translate product and user needs into scalable, low-latency solutions and run experiments (A/B tests, feature flags) to continuously improve performance and impact.
  • Collaborate closely with Product Leads, Frontend, Data, and Machine Learning teams to build features like search, ranking, personalization, and data-pipeline integrations.
  • Drive reliability, observability, and efficiency - through automated testing, logging, tracing, alerting, incident response, and post-mortems.
  • Continuously improve  technical quality by reducing tech debt, proposing architectural improvements, and measuring their outcomes.

Our humble expectations: 

We’re looking for someone with:

  • Around 3 - 6 years of experience in backend development using Kotlin. Python and Go experience is highly valued as well. 

  • A strong ownership mindset - someone proactive, curious, and eager to understand how things work under the hood.

  • A product- and customer-focused approach, with a pragmatic attitude toward solving real user problems.

  • Excellent communications skills in English

Why You’ll Love Working Here: 

  • Make an impact: Build features used by millions across multiple countries. 

  • Own it end-to-end: Design, build, and operate high-performance backend services with real product impact.

  • Work with great tech stack: Kotlin at the core, plus Go and Python for scalable, modern systems.

  • Collaborate & innovate: Partner with Product, Data, and ML teams to create personalized, data-driven user experiences.

  • Grow & learn: Improve architecture, reliability, and performance in a culture that values ownership, curiosity, and teamwork.
