For an international retail organisation, we are looking for a Senior / Principal Backend Engineer.
Assignment
The organisation is further developing and professionalising digital platforms that are used internationally. For the backend engineering team, we are looking for a highly experienced engineer who can contribute hands-on within a complex, high-traffic and API-driven environment.
The backend consists of scalable services built primarily with Node.js and TypeScript, using both REST and GraphQL. The GraphQL landscape uses Apollo GraphQL Federation, where individual subgraphs form part of a wider supergraph architecture. You will work within this existing production architecture, contributing to its continued development, scalability, performance, reliability and maintainability.
This role goes beyond developing individual APIs or features. You should be comfortable analysing complex technical and architectural challenges, making engineering decisions and understanding their implications within a distributed microservices landscape. You will work alongside other experienced engineers and contribute to technical decision-making, backend architecture and the technical roadmap, while remaining actively involved in hands-on development.
The technical level within the team is high. We are therefore looking for an engineer who not only has experience with the technologies involved, but can also explain how and why particular engineering and architectural decisions were made and applied in production.
What will you be doing?
- Develop and maintain backend services using Node.js and TypeScript.
- Design and.
