Senior Backend Engineer, Revenue

We're looking for a Senior Backend (Golang) Engineer to join the Ads Team in the Vinted Marketplace domain. Our goal is to build an internal ads platform that will deliver a native ads experience at scale, integrating ads into all areas of Vinted and significantly contributing to the overall revenue. You’ll collaborate with experienced colleagues to develop a robust and scalable platform.

The project is still in the early stages, we are building many things from scratch, so prepare to move fast and try out a bunch of new things. We are constantly building new features and evolving existing ones, with experimentation being 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.

• See your code to affect millions of users almost instantly. _Our main branch gets rolled out straight to production on each merge. We deploy many times per day._
• Work with diverse tech stack, including: languages: Go, Ruby, Scala; databases/storage: MySQL, monitoring/observability: Prometheus, Grafana, data streaming: Apache Flink . _We don't expect you to be familiar with all of them beforehand, but we expect you will be excited to learn them fast._
• Apply different levels of testing: from testing your code to performance testing to investigate various potential bottlenecks.
• Take ownership of critical alerts and business metrics for your team to ensure our services achieve 99.99% availability.

• You have solid backend engineering skills, with expertise in Golang or similar programming languages.
