Software Engineer - Global Expansion

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. The Data Developer Experience team is looking for a Senior Software Engineer to build core services for our Data Platform. The team builds the Data Control Plane, a Go-based internal Terraform- or Kubernetes-like platform which allows users and other services to configure and operate Data Platform infrastructure. Our mission is to meet the massive data scaling needs of a global organization with a platform that is simple yet powerful, self-healing, agentic-safe, trustworthy, snappy, and cost efficient. WHAT YOU’LL BE DOING * Designing - you align our ambitions and stakeholder needs on a feature level. You collaborate with the team to propose well fitting solutions using RFCs. * Building - you develop Go code with agents. The implementation may target a backend service, our plugin framework, CLI tooling, CI/CD pipelines, or even our React frontend app. * Documenting - you ensure high quality, curated markdown documentation for users, AI agents, and maintainers / on-call. * Operating - you strive for operational excellence with constant vigilance, proactivity, and on-call participation to ensure we provide a robust platform for business critical workloads. * Supporting - you understand the needs of diverse data platform users and guide them to golden paths. OUR HUMBLE EXPECTATIONS * You have a proven track record of designing, building, and operating large-scale distributed systems and/or platforms. * You bring deep experience with Go, but you possess a polyglot mindset and are happy to dive into Python or other languages when the problem calls for it. * You have hands-on experience building, maintaining, and optimizing CI/CD pipelines. * You possess a strong foundational understanding of networking and security best practices. * You are familiar with data platform architecture and technologies, specifically columnar databases/storage and MPP engines. * You are passionate about Developer Experience and excel at balancing user needs with technical and platform constraints. * You actively leverage agentic coding as your preferred workflow to accelerate value delivery, while maintaining the critical eye needed to rigorously vet and secure code for robust systems. WHAT’S IN IT FOR YOU * A rare opportunity to join a near-greenfield project building state-of-the-art, robust, scalable foundations for the future. * Work in a Big Tech-adjacent environment with brilliant colleagues, modern tooling and practices, and large scale. 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.

Wolt is part of DoorDash — together we form one of the world's largest local commerce platforms, operating across DoorDash, Deliveroo, and Wolt markets in 40+ countries. Our Consumer organisation sits at the intersection of machine learning and customer experience, responsible for helping millions of customers every day find the right restaurants, dishes, and items in search, personalised recommendations, and discovery surfaces that feel intuitive and relevant. It's a domain where scale is truly global, the engineering and applied science problems are genuinely hard and scientifically interesting, and the impact on the customer experience and our business metrics is immediate and measurable. We’re looking for an Applied Scientist to join our Consumer org. In this role you’ll work on some of the most technically challenging ML problems across DoorDash: understanding what our customers are looking for, identifying key concepts in their queries and surfacing the most relevant results. You'll be embedded in a cross-disciplinary team of engineers, ML engineers and applied scientists with full ownership from research to production. If your expertise matches our domain and you want to work on hard problems at global scale alongside exceptional colleagues, we'd love to meet you. WHAT YOU’LL BE DOING As an Applied Scientist in Consumer, you’ll advance the ML models and methods that power how customers across DoorDash, Deliveroo, and Wolt find and discover content. You’ll work end-to-end collaborating closely with engineers and product managers to deliver real impact. DAY-TO-DAY IN THIS ROLE YOU’LL: * Design and develop ML models for search relevance, query understanding, and ranking that operate across DoorDash, Deliveroo, and Wolt’s 40+ markets. * Bring state-of-the-art solutions to our stack for the delight of our customers, helping the team to impact business metrics. * Work end-to-end on ML problems: from problem framing and data analysis through model development, offline evaluation, and production monitoring. * Collaborate with Software Engineers, ML Engineers, Product Managers, and Analysts to translate research insights into real customer impact. * Contribute to our group-wide Applied Science community through knowledge sharing, technical reviews, and raising the bar on ML practices. OUR HUMBLE EXPECTATIONS*  * You have 4+ years of hands-on experience in applied ML with a track record of shipping models to production (a PhD in ML with applied research experience is equally welcome). * You have solid experience in Search: query understanding, query intent prediction, or semantic search. * You are proficient in Python and experienced with ML frameworks and large-scale data processing. * You communicate complex technical ideas clearly and collaborate effectively with cross-functional teams. * Experience with NLP, dense retrieval, learning-to-rank, or embedding-based methods is a strong plus. WHAT WE OFFER In this role, you will have a direct and measurable impact on millions of customers every day. You’ll join a team of world-class applied scientists and engineers in DoorDash, Deliveroo and  Wolt who care about both rigour and craft, tackling problems that are genuinely hard and impactful in ways that few companies can offer. Together with your lead, you will have the opportunity to create a personalised development plan to grow your strengths and to develop new capabilities. 📍 This role can be based in one of our tech hubs in Berlin, Helsinki, or Stockholm, or you can work remotely anywhere in Finland, Sweden, Germany. We also offer relocation support to help you join us. NEXT STEPS* Once you apply, you will go through 4 steps in our hiring pipeline: * TA Screen: a 30-minute introductory call with one of our Talent Partners to learn about your background and tell you more about the role. * Hiring Manager interview: a conversation covering your domain experience in Search or Personalisation, past projects, AI fluency, and ways of working. We will tell you more about the team, use cases, our tech stack, etc. and it will be your opportunity to ask questions. * Coding & System Design: a technical session focused on ML system design and problem-solving with some of the team’s ML Engineers. * Project / Expertise Deep Dive: an interview with the team’s Applied Scientists, going deep on your domain expertise and past projects.
