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.
At Wolt, customer experience is everything. From the moment someone opens our app to the final delivery, we’re dedicated to creating seamless, delightful experiences. But that’s not enough—we’re going beyond. Our Conversational AI team is building the future of AI-powered customer support, and we want you to be part of it.
We're not just reacting to problems—we aim to solve them before they arise, using state-of-the-art AI and Large Language Models (LLMs) to automate, streamline, and elevate the support experience for our users across 30 countries. The Conversational AI team plays a central role in this transformation by building intelligent systems that anticipate and prevent issues before they occur, helping millions of customers get what they need faster and more efficiently.
Customer support is a competitive advantage. We intend to augment the efficiency of support associates by giving them AI tools that will enhance their capabilities and productivity.
What you’ll be doing
As a Fullstack Engineer, you’ll build and maintain core backend services that power conversational features in the Wolt app. This is a high-impact role with strong ownership, end-to-end responsibility, and the opportunity to shape the next generation of intelligent support experiences.
- Design, build, and maintain backend services using Python (FastAPI) and TypeScript, which integrate with real-time AI support workflows.
- Collaborate closely with ML engineers, designers, and product managers to build features that solve real user problems.
- Take full ownership of the development lifecycle—from ideation and implementation to automated testing, deployment, and monitoring.
- Ensure high performance, scalability, and maintainability of systems across markets and use cases.
- Contribute to architectural and technical decision-making in a fast-moving, iterative development environment.
- Break down complex product features into technical tasks and prioritize work effectively.
Our humble expectations
We expect you to bring between 4 and 6 years of commercial software development experience, with at least 2 of those years focused on Python in production environments, and 1 year developing using NodeJs + TypeScript. You should have a solid understanding of backend development practices, including API design, service architecture, and database design.
Experience developing frontend with TypeScript + React, as well as experience with MongoDB is big plus. You must be comfortable taking ownership of testing, writing, and maintaining unit, integration, and functional tests without the support of a dedicated QA team.
You should be familiar with Kubernetes, AWS, Terraform, and CI/CD pipelines such as GitHub Actions. We value self-driven individuals who thrive in autonomous environments and take initiative to solve problems proactively.
📍The role is based in Helsinki or Tallinn. We maintain a remote-friendly setup to foster innovation and teamwork.
