Lead Backend Engineer, Marketplace Payments (Limited-time Relocation Bonus)

We're searching for a Lead Backend Engineer to join one of our engineering teams in the Marketplace Payments domain. Our goal is to build secure & reliable payments solutions for all Vinted buyers and sellers. You’ll collaborate with experienced colleagues to own the critical lifecycle of a user’s financial journey. This means architecting the systems that power a user’s first sale and balance activation, ensuring seamless payment account creation across multiple PSPs. You will lead the charge in navigating the complexities of KYC/KYB and identity verification within an environment of ever-changing regulatory requirements. You and the team will drive the high-stakes execution of user migrations between different PSPs and payment licenses, all while maintaining the scalable, resilient core platform that ensures smooth payment account lifecycle for the entire Vinted Marketplace.

This is a fast-paced environment at the beginning of our journey, so we embrace uncertainty. We're constantly building new services and evolving existing ones, with experimentation being a key. We balance the "fail fast" principle to avoid analysis-paralysis, but we also take the time to understand the benefits of different alternatives before diving in. We're not afraid to make mistakes. We learn from them.
