Senior Backend Engineer, Purchase Domain, Pre-order Shipping Team

At Vinted, backend engineers are part of cross-functional product teams that include Mobile, Web, and Backend engineers, as well as a product manager, designer, and decision scientist. Backend engineers are responsible for implementing business logic, developing APIs for our mobile and web platforms, and scaling our backend systems to meet growing platform needs.

The Purchase domain guides members from the initial intent to buy to the successful purchase of the desired item. It is composed of several teams that work on delivering smooth checkout, payment, shipping, and messaging functionality to our users.

We're looking for a Senior Backend Engineer to strengthen the Pre-order Shipping team. The team is focused on ensuring a seamless, reliable shipping experience for Vinted users from the moment users start browsing items through to buyers completing their purchase.

Our team is seeking a Senior Backend Engineer who writes clean, elegant code and enjoys working on large-scale projects. Your main goal will be to help evolve our product to meet future challenges, while contributing to Vinted's mission of making second-hand the first choice, all with a strong focus on delivering an exceptional shipping experience.
