Job description

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.

Wolt+ is Wolt's subscription service - available across 29 countries and one of the most impactful products in the business. We make Wolt more affordable and more engaging for our most loyal customers. The product is growing fast, the scope is expanding globally (we're building it together with DoorDash and Deliveroo), and we're only getting started.

We're hiring backend engineers who want to be at the front line of what engineering looks like in the age of AI.

Why Wolt+?

• An AI-first team by design. We don't use AI as a productivity add-on - we treat agentic coding as a core engineering discipline. We expect our engineers to build with AI agents, to challenge what's possible when the human-in-the-loop is a multiplier rather than a bottleneck, and to push the boundaries of what a small, focused team can ship.


• Real ownership, real impact. Wolt+ runs in 29 countries, touching millions of users daily. You'll own features end-to-end - from the idea through production - and see your work matter at scale.


• Cross-org engineering at the frontier. We work closely with DoorDash and Deliveroo to align subscription experiences across three of the world's leading delivery platforms. This is engineering at the intersection of product ambition and international complexity.


• A small team that punches above its weight. We're a cross-functional team: Backend, Mobile, Web, Product, Design, and Data - all in the same room. No handoff theatre. You'll move fast, ship iteratively, and be around people who take craft seriously.

AI-First Engineering - What This Means Here

We're building teams at the forefront of agentic coding. This isn't about using Copilot to autocomplete boilerplate. We mean engineers who:

• Design workflows where AI agents handle entire task loops, from spec to PR.


• Think in terms of orchestration: what does a human review, what does the agent own?


• Build internal tooling and abstractions that make AI-assisted development faster and more reliable for the whole team.


• Stay curious and ahead of the curve - trying new models, agents, and tools as they emerge, and forming strong opinions about what's genuinely useful vs. hype.

What We're Looking For Across all roles

• Strong engineering fundamentals - you've built and shipped software that runs at scale, and you understand what that entails: testing, observability, reliability, and maintainability.


• Genuine enthusiasm for AI-first development. You use AI tools daily and have formed real opinions about how to get the most out of them.


• Ownership mentality: you drive projects forward, communicate clearly across teams and time zones, and don't wait to be told what to do.


• Collaborative instincts - Wolt+ sits at the intersection of consumer mobile, web, backend, and data. Cross-functional work is the norm, not the exception.

About You

• You've built and shipped real software - products, platforms, APIs, apps - and you know what it takes to keep things running reliably in production. You have opinions about architecture but hold them lightly. You write tests. You read the alerts. You don't leave loose ends.


• What sets you apart right now is that you're genuinely excited about where engineering is going. You've been experimenting with AI agents and agentic coding workflows - not because someone told you to, but because you couldn't help yourself. You think about how to redesign your development loop from first principles, not how to bolt AI onto the way you already work.


• You communicate well, collaborate easily across disciplines, and care about the product as much as the code. You're the kind of engineer who asks "what's the best way to..." and then actually follows through.
