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 

We're building teams at the forefront of agentic coding. This goes beyond autocomplete or occasional prompting. We’re looking for 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.

If you find yourself naturally asking "can an agent do this?" before reaching for the keyboard, you'll fit right in.

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. 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: Discovery is one of the most critical parts of the product. You’ll own features end-to-end and see your work directly influence user behavior at scale.
• Cross-functional collaboration: You’ll work closely with product managers, designers (including motion), backend engineers, and data teams to build seamless user experiences.
• 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.

What we’re looking for

• Solid engineering fundamentals: 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, from breaking down problems into technical tasks to ensuring features are tested, stable, and successfully shipped
• Ability to work independently and drive projects: You’re comfortable owning work end-to-end with minimal guidance, collaborating with designers to clarify requirements, creating tasks, and moving initiatives forward
• Product and execution thinking: You operate well in ambiguous environments and contribute not just to implementation, but to shaping what gets built and how
• Experience operating in production environments: You’ve debugged real issues in live backend services and understand what it takes to maintain reliability at scale
• Collaboration and communication: You communicate clearly and work effectively across teams, including in multi-team development environments

🌍 Where You’ll Work

You will be based in Helsinki, and be a part of a distributed, cross-functional team with engineers in Berlin and Helsinki. We operate in a remote-friendly environment designed to encourage collaboration and innovation.

Next steps

These positions will be filled as soon as we find the right persons, so make sure to apply as soon as you realize you really, really want to join us!

Every order on Wolt passes through us. The Cart & Checkout team owns the critical path from the moment a customer adds something to their cart to the moment they Slide to order - and the experience that follows. We run in 29 countries, handle millions of daily transactions, and build the surfaces that every other team depends on.

We’re hiring a senior backend engineer who wants to be at the front line of what engineering looks like in the age of AI - and who wants to do it on systems that genuinely matter.

💡 Why Cart & Checkout?

• We've shipped features millions of customers use daily: Double order, persistent baskets, group orders, scheduled delivery, tipping, reviews and so on. The team builds and owns these end-to-end. You'll join a team with a strong track record and keep that momentum going.
• Real ownership, real impact: You’ll own infrastructure at our highest criticality level. When it’s down, ordering is down. Your work shows up directly in conversion metrics across every Wolt market.

• Technical ownership and high-priority projects: Your time is split between maintaining and evolving critical services and shipping visible features along the main user path. No pure maintenance. No feature factory.
• Cross-org engineering at scale: We co-own checkout APIs that serve Wolt, DoorDash, and Deliveroo clients simultaneously - aligning ordering experiences across three of the world’s leading delivery platforms.
• Competitive pay and equity: Salary + DoorDash RSUs. When the company wins, you win.

🤖 AI-Native Engineering - What This Means For Us

• We’re building a team 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 developing a clear perspective on what’s genuinely useful vs. hype. If you find yourself naturally asking “can an agent do this?” before reaching for the keyboard, you’ll fit right in.

🔍 What We’re Looking For

• Strong backend engineering fundamentals: you've built and shipped services that run at scale, and you understand what that entails: API design, observability, reliability, and maintainability.
• Genuine enthusiasm for AI-first development: You use AI tools daily, have real perspective on how to get the most out of them, and want to push what's possible when AI agents are part of the engineering workflow.
• You take responsibility for outcomes end-to-end: from design through production, across teams and time zones.
• Collaborative instincts: Cart & Checkout sits at the intersection of purchase, pricing, payments, logistics, and so many others. Working across disciplines is the norm, not the exception.
• Experience with Python, Kotlin, or Go: We’re language-pragmatic but these are what we run - and you should feel at home in at least one.

🙌 About You

You care about the product as much as the code. You have opinions about architecture but hold them lightly. You communicate well, share context generously, and build trust with the people you work with - across engineering, product, and design.

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.

For day-to-day work, our engineers are organized into smaller cross-functional feature squads or system-level teams. These teams have a great deal of autonomy and are responsible for the development and architecture of their features and systems. They take full ownership of their code and handle everything from concepting, design, and implementation to release, maintenance, and bug fixes.

We are looking for experienced Senior Android Engineers to join our app development organization. We have several roles available across various teams, from developing new member-facing features to building the foundational systems that ensure seamless connectivity and data synchronization between the Oura Ring and the app. Whether you are passionate about crafting beautiful user interfaces or architecting robust, scalable low-level systems, we have a place for you.

This role is on-site or remote within Finland, with a preference for candidates who can regularly visit our offices in Helsinki or Oulu.

What You will do

• Architect, design, build and maintain features to the Oura Android app using Kotlin, Compose, Room, Coroutines and Flow.
• Work in a cross functional squad together with a passionate group of engineers, designers, data scientists, our product manager, health science experts and other stakeholders.
• Refactor existing features to improve code quality, performance, and maintainability.
• Ensure high quality through code reviews, automatic testing, and engineering best practices.
• Use Kotlin flows and coroutines for efficient asynchronous programming and handling complex state flows in the UI.

Who You are

We believe you’ll succeed in this role if you have a genuine passion for building high-quality products and a strong sense of ownership. You thrive in a collaborative environment and are driven to create meaningful value for end-users.

We would love to have You on our team if You have:

• A minimum of 8 years of professional development experience shipping Android apps.
• Strong experience with Kotlin and modern Android app architectures.
• Taking strong ownership of the Android team’s work from technical planning to ensuring we ship working and high quality features.
• A proactive, get-stuff-done attitude.
• Drives and delivers on complex and often ambiguous initiatives with minimal guidance
• Thriving in a dynamic startup-like environment. We're building something completely new within the Oura app, and many of us come from startup backgrounds. We move and experiment fast, with continuous product discovery ongoing. We believe in creating value through iterative and incremental development as opposed to big bang releases.
• Solid understanding of what you build as a whole, both from an engineering and end-user perspective.
• Problem-solving mindset and adaptability.
• Strong collaboration and communication skills.
• Experience with collaborative development on complex shared codebases.
• A focus on quality through automated testing

Benefits

What we offer:

• Competitive salary

If you are passionate about improving people's health and want to contribute to a product that millions of people use and love, we would love to hear from you!

We are looking for a Senior Software Engineer, DataFlow (Android), to focus on core Android components responsible for storage and movement of data between Oura’s mobile app and cloud.

We’re looking for exceptional people. If you lack “senior-level” experience but are otherwise highly capable please do apply.  Staff+ engineers will also be considered, though make that clear in your application.

This role is hybrid, as you'll work a day or so a week at the Helsinki Office at Pohjoisesplanadi 37. We don't have any strict policy on this as a company, but as a team we appreciate spending some time face to face.

Team size: 6-10

DataFlow team core mission:

• Reduce the effort required to store and query data that needs to be available in Oura’s app and across the cloud
• Empower feature teams to develop end-to-end features without the need to involve backend engineers.
• Evangelize compliance with standardized data schemas, data quality and data lifetime management.
• Ensure our systems are performant, scalable and cost-efficient, able to handle millions of active users and PBs of data.

The dataflow team is a platform team - most of the work is internal-facing. UI work is rare.
The team includes android, iOS,  backend, and “full-stack” engineers that do both app-side and backend work.

This role:

You will be one of the core Android engineers for this team. The focus area may naturally shift over time but the following provides an idea of the work being done:

• Writing kotlin code (for the most part)
• Improving app-cloud data sync, including: reliability, latency, performance, observability.
• Improving app-side data storage: performance, data access api design, data migration systems, etc.
• Implementing automation and codegeneration layers.
• Supporting a variety of work in the platform domain, including data management and more.

You will participate in both design and implementation work. This being a platform team with internal users, we expect team members to be proactive in identifying opportunities for improvement at feature and architecture level.

Technologies:

• Android: Kotlin, (with some C++ libs, mostly in other domains), RealmDB (we’re migrating away from it), Sqlite
• Backend: Python, Rust, AWS
• Misc: some TypeScript

We believe great engineers have a solid understanding of the fundamentals and learn quickly. Hence it’s more important that you can showcase excellence than having experience with specific tech.

What we’re looking for:

• Experience with mobile development
• Ideally, proficient in Kotlin programming and modern Android app architecture. iOS experience is also considered.
• Previous experience solving challenging technical problems.
• Broad knowledge of software fundamentals, testing, concurrency, databases, and system design.
• Ability to take ownership of projects, design technical solutions, drive implementation, and deliver results with limited guidance.
• Ability to mentor other engineers and increase developer productivity across teams.
• Ability to produce high quality code quickly (with and without AI) -  you identify yourself as a prolific programmer.
• Driven by value creation and overall impact.
• Team player with great spoken and written communication skills.
• Motivated to learn and further develop your skills

Not required but potentially relevant:

• Knowledge of distributed systems, data syncing mechanisms and challenges (data consistency, etc).
• Experience with HTTP API design: if interested, there is potential to work on both the backend APIs and the Android integration for new features
• Experience with JNI and C/C++ code.
• Experience writing highly performant code at lower and higher level, including application profiling.
• Knowledge of iOS - if interested, there is potential to contribute on both Android and iOS.
