Mobile Engineer, iOS Android

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, we're building products that millions of people rely on every day. Behind every great customer experience is a solid engineering foundation, and that's where you come in.

We're looking for experienced iOS or Android engineers who enjoy solving problems beyond feature development. If you're excited about building scalable mobile foundations, improving developer experience, raising engineering quality, and helping other engineers build better software, we'd love to talk.

We're also embracing a new way of building software. AI is becoming a core part of how we engineer products, and we're looking for people who are curious about how AI can improve software development, not just generate code.

What you'll be doing

As a Mobile Engineer (iOS or Android), you'll work on the foundations that enable product teams to deliver high-quality mobile experiences at scale.

Depending on your background and interests, your work may include:

Building and evolving Android architecture, shared libraries and platform capabilities

Improving developer experience through tooling, automation and better engineering workflows

Driving improvements in app performance, reliability and observability

Designing scalable systems that help teams move faster without compromising quality

Working closely with engineers across multiple product teams to solve shared technical challenges

Leading technical initiatives and helping raise the engineering bar across the organization

Exploring how AI can improve engineering workflows and developer productivity

Building reliable guardrails and tooling around AI-assisted software development

This role is ideal for someone who enjoys making other engineers more productive, thinking about long-term technical health, and solving engineering problems that have impact across multiple teams.

Our humble expectations

We're looking for engineers who have experience with most of the following:

Strong experience building Android applications with Kotlin or iOS applications

Experience designing scalable mobile architectures and shared platform components

Good understanding of iOS or Android ecosystems and modern development practices

Experience with CI/CD, automation or developer tooling

Strong software design and system thinking

Experience collaborating across engineering teams and influencing technical decisions

Comfortable mentoring other engineers and driving technical initiatives

Excellent communication and stakeholder management skills

We'd especially love to meet engineers who:

Use AI regularly as part of their engineering workflow

Have experimented with modern AI development tools such as Claude Code, Cursor, Gemini, Codex, Copilot or similar

Are curious about agentic development workflows and AI-assisted software engineering

Know when to trust AI, when to challenge it, and how to build reliable engineering workflows around it

You'll stand out if you've also worked with areas such as Kotlin Multiplatform (KMP), server-driven UI, experimentation frameworks, mobile observability, or large-scale consumer mobile platforms.

This role can be based in one of our tech hubs in Helsinki or Stockholm.

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.
