## About the Role

* An AI-first mindset, with a deep experience in leveraging modern AI tools and solid engineering principles to solve problems end-to-end, independently of any specific technology stack.
 * Proven experience building production software in backend, frontend, or fullstack environments end-to-end and at scale.
 * Strong expertise in at least one area of the stack, with a willingness to contribute outside that area when needed.
 * Experience with a modern backend language such as Go, Kotlin, Java, or similar, and/or modern frontend technologies such as TypeScript and React.
 * Good understanding of APIs, databases, testing, and software design fundamentals.
 * The ability to work independently on well-scoped problems and collaborate effectively with others.
 * Good communication skills and a pragmatic, collaborative mindset.

You do not need to be equally strong in frontend and backend. We welcome different balances of experience. You might be primarily a backend engineer who is comfortable making frontend changes when needed, or a frontend-focused engineer who is happy to work with APIs and backend services.

What matters most is that you are comfortable working across boundaries to deliver the right solution.

Experience in one or more of the following areas would be a plus:

 * Merchant-facing or internal operational tools.
 * Analytics, recommendations, or decisioning systems.
 * Grocery, retail, restaurants, logistics, or marketplace technology.
 * Integrations with external business systems.
 * Kafka or other streaming technologies.
 * Cloud infrastructure such as AWS, Kubernetes, or Docker.

You'll work on products that directly affect how merchants interact with Wolt, Deliveroo and DoorDash across Europe. The scope is broad and close to the business, giving you the opportunity to work on meaningful problems across different parts of the merchant journey while developing your skills across the stack.

## Description

As a Fullstack Engineer, you'll contribute to products and services used across the merchant experience. You'll:

 * Build and maintain production software across backend services and user-facing applications.
 * Work on areas such as merchant onboarding, analytics, recommendations, menu and order management, integrations, or merchant-facing tools.
 * Develop reliable APIs, data models, services, and user-facing features.
 * Collaborate closely with product managers, designers, operations, and other engineers to turn business needs into practical technical solutions.
 * Own features from implementation through production and ongoing maintenance.
 * Contribute to technical design discussions and improve the quality, scalability, observability, and maintainability of our systems.
 * Use AI-assisted development tools effectively as part of your engineering workflow, while critically evaluating their output and taking ownership of the final solution.
 * Be willing to work outside your primary area of expertise when needed to solve the problem end-to-end.

 * Ownership: Engineers take responsibility for the features and services they work on, from development to production.
 * Collaboration: We work closely across engineering, product, design, data, and operations.
 * Pragmatism: We value simple and maintainable solutions that create business impact without unnecessary complexity.
 * Flexibility: We care more about solving the problem than strict frontend or backend boundaries.

Our backend services primarily use Go and Kotlin, while our frontend applications use technologies such as TypeScript and React.

We also work with technologies including Kafka, PostgreSQL, MongoDB, Redis, AWS, Kubernetes, Docker, gRPC, and modern cloud infrastructure.

We're looking for engineers who have
