[Hiring] Junior Backend Engineer, Discovery @Wolt - English

Role Description

We’re looking for passionate and product-minded Backend Engineers to join our Discovery team - the group behind some of the most visible and impactful parts of Wolt’s consumer app. You’ll work on features that help millions of users discover their next favorite restaurant, grocery store, or product - from the homepage and category views to new vertical experiences like groceries, electronics, pet food, and health & beauty.

This is more than just a backend engineering role. We’re looking for someone who combines strong technical skills with curiosity, ownership, and a deep interest in creating meaningful user experiences at scale.

AI-First Engineering in Discovery

• 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 you’ll do:

• Design, build, and operate high-performance backend services - primarily in Kotlin and Go (experience with Python is a plus) - powering discovery surfaces, front pages, and category experiences across Wolt’s new and existing verticals.
• Own your services end-to-end: from requirements, design, and delivery to testing, CI/CD, deployment, monitoring, and on-call.
• Translate product and user needs into scalable, low-latency solutions and run experiments (A/B tests, feature flags) to continuously improve performance and impact.
• Collaborate closely with Product Leads, Frontend, Data, and Machine Learning teams to build features like search, ranking, personalization, and data-pipeline integrations.
• Drive reliability, observability, and efficiency - through automated testing, logging, tracing, alerting, incident response, and post-mortems.
• Continuously improve technical quality by reducing tech debt, proposing architectural improvements, and measuring their outcomes.

Why this role?

• Join our Discovery team and shape how users experience Wolt from the moment they open the app.
• 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.
• Real ownership, real impact: Discovery is one of the most critical parts of the product.
• Cross-functional collaboration: You’ll work closely with product managers, designers (including motion), backend engineers, and data teams.
• A small team with high leverage: We operate as a tight, cross-functional team where engineers have a strong voice, move fast, and take responsibility for what they ship.

Qualifications

• At least 1-2 years of experience building production backend services.
• 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.
• End-to-end ownership mindset: You take responsibility beyond implementation.
• Ability to work independently and drive projects: You’re comfortable owning work end-to-end with minimal guidance.
• Product and execution thinking: You operate well in ambiguous environments.
• Experience operating in production environments: You’ve debugged real issues in live backend services.
• Collaboration and communication: You communicate clearly and work effectively across teams.

Where You’ll Work

You can be based in Helsinki or Stockholm, and you’ll be part of a distributed, cross-functional team with engineers across Berlin and Helsinki. We operate in a remote-friendly environment designed to encourage collaboration and innovation.

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.
