Information About The Position We're hiring a Senior Backend Engineer II to join the Engineering Experience domain in Vinted's Platform unit. Our domain builds the tools, platforms and golden paths that the rest of Vinted Engineering relies on every day - from the first line of code an engineer writes to the moment it runs safely in production.

Development Environments & AI is responsible for development environments and the engineering AI tooling ecosystem. Its flagship is Spinup, a cloud development environment that lets engineers and coding agents validate changes in remote environments without the complexity of managing local services. The team also leads the adoption of AI-assisted engineering across the company.
