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 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 are the Support Engineering Group, the team responsible for delivering a seamless support experience to Wolt’s 50M+ users and 300K+ partners across the globe. Our mission is to provide fast, effective help to every customer, merchant, and courier whenever they need it. We deliver this by building intelligent self-help flows, powerful automations, and a world-class, in-house chat platform that makes getting support effortless.
To bring this vision to life, we are looking for a Senior Fullstack Engineer to help build the next generation of the support experience. You will craft new intuitive chat interfaces, self-help flows, and automated tools that our customers, merchants, and couriers interact with directly. Your core challenge is to build a robust and elegant experience that feels tailor-made for each distinct user group, while scaling seamlessly across dozens of countries and languages. If you are passionate about creating world-class systems that help millions, we invite you to join our team in either Helsinki 🇫🇮 or Tallinn 🇪🇪. Read more about our hybrid setup here.
