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. New Verticals is everything our customers buy that isn't a restaurant meal: groceries, pharmacy, electronics, the shop on the corner.

As a Senior Mobile Engineer, iOS - you'll join New Verticals EMEA, the group accountable for that mission across Wolt and Deliveroo in 30+ countries, organised as five teams. Your home team owns quality and cost: making sure customers actually get what they ordered, at a sensible cost of getting a basket to their door. Substitutions, unavailable items, order accuracy - invisible when it works, infuriating when it doesn't. You won't only work there: mobile expertise is in demand across all five teams, and part of the role is going where the iOS work is. This role is primarily focused on native iOS development. Experience across both iOS and Android, as well as backend development, is a strong plus. What you’ll be doing Building, improving and maintaining native iOS features for customer-facing journeys within our shared consumer apps. Partnering closely with product, design and engineering colleagues to turn customer and business needs into simple, reliable and scalable mobile e

You'll spend most of your time in our micro-frontend layer, building the interfaces admins use to compose and manage Blueprints. Backend development is not expected: over time you'll grow comfortable reading and debugging the Java services your UI depends on, but that's a bonus, not a day-one requirement. You'll work in a close-knit agile team, developing new features, breaking down customer problems, and owning the areas you touch. As part of an international ART, you'll collaborate daily with engineers in Czechia and Poland, and join a team that knows the Blueprints domain deeply and is invested in bringing new members up to speed - with a clear onboarding path, a manager who runs regular 1:1s and cares about your growth, and space to learn Apple device management on the job.
