Senior Software Engineer - Full Stack (Merchants)

Ownership: Senior engineers take responsibility not only for implementation, but also for understanding the problem, shaping the solution, and ensuring it works successfully in production.

Collaboration: We work closely across engineering, product, design, data, and operations. Senior engineers are expected to help drive alignment when problems span multiple teams or areas.

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:

An AI-first mindset, with strong experience leveraging modern AI tools alongside solid engineering principles to solve problems end-to-end, independently of any specific technology stack.

Strong experience designing, building, and operating production software at scale in backend, frontend, or fullstack environments.

Experience owning complex features, services, or technical initiatives from problem definition through production and ongoing operation.

Strong understanding of system design, APIs, databases, distributed systems, testing, observability, and production reliability.

Experience making technical and architectural decisions where there are multiple valid approaches and meaningful trade-offs.

A track record of helping other engineers grow through mentoring, technical guidance, code reviews, or knowledge sharing.

Strong communication skills, including the ability to explain complex technical decisions clearly to both technical and non-technical stakeholders.

Experience with a modern backend language such as Go, Kotlin, Java, and/or modern frontend technologies such as TypeScript and React.

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.
