Tallinn, Harjumaa, Estonia Wolt - English Full time €90,000 - €120,000 per year
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.

Engineering the future of customer support — at a global scale

As we scale our operations from 30 to 60 countries, supporting millions of users and partners, our internal tools need to scale with us. The Support Engineering group is at the heart of this mission. We build high-performance admin applications and core operational tools that empower our support teams to work smarter and faster. A key part of this is our in-house chat platform, which already handles around 5 million conversations every month. On top of this foundation, we're developing advanced features to reduce manual work, improve communication, and proactively resolve issues — often before our users even notice them.

Our systems range from automated reach-outs for delayed orders to deeply integrated tools that enable our support teams to deliver assistance quickly, reliably, and with a human touch. By removing inefficiencies and automating repetitive tasks, we're ensuring that Wolt's 25M+ users and 300K+ partners receive world-class support at scale.

We're now looking for a Backend Engineer (Golang) to join us in building scalable, low-latency systems that power these tools and shape the future of customer support at Wolt. You'll work on impactful products that directly influence how millions of people experience Wolt every day.

This role can be based in one of our tech hubs in Helsinki, Berlin or Tallinn. 

What you'll do:
  • Build and maintain high-throughput backend services using Go.
  • Collaborate with product managers, designers, and frontend developers to ship features that support internal support agents across the globe.
  • Design systems that are scalable, resilient, and easy to maintain.
  • Lead and contribute to architectural discussions and technical decision-making.
  • Write well-tested code and help the team maintain high code quality standards.

Our humble expectations:
  • 7+ years of professional software engineering experience, with a proven track record of building and scaling complex systems.
  • Experience working with Golang in production (at least 2+ years), with the ability to mentor others and drive best practices across the team.
  • Strong hands-on experience with both SQL and NoSQL databases — especially Cassandra.
  • Solid understanding of designing and operating low-latency, high-throughput distributed systems.

Nice to have

  • Background in or other backend languages.
  • Familiarity with cloud infrastructure (AWS, GCP) and event-driven architectures.
  • Previous on-call experience, with a pragmatic approach to reliability and incident management. We support healthy, balanced on-call practices and make sure responsibility is shared fairly.
What we value
  • A product-oriented mindset — you think beyond the ticket, understand the "why" behind the work, and aim to create real impact for users, having a high level of resposability.
  • Experience leading projects or making key technical decisions, especially in fast-paced environments.
  • Clear and proactive communication skills, with a collaborative spirit — we move fast, but we succeed together.
  • Commitment to inclusivity: we value diverse perspectives and encourage people from all backgrounds to apply, even if you don't meet 100% of the requirements.
Next steps:

We review applications on a rolling basis and encourage you to apply as soon as you feel excited about this opportunity. If you need any adjustments in our hiring process (for example, related to accessibility, caregiving, or personal circumstances), let us know — we'll be happy to support.
