Head of Core Services Development Team

at VK, Moscow

We are working on the largest content platform in the Russian internet — in terms of volume, formats, consumption time, and audience. Millions of RPS and petabytes of data are the main challenges for VK's backend. Core Backend is the product infrastructure layer that forms the foundation and allows different teams to move forward without solving the same problems.

We are looking for a Head of Core Services Development Team who wants to solve complex problems and directly influence VK's architecture.

• Comments. A unified service for working with comments for any entities — posts/videos/clips. Unified and customizable logic for easy integration into any product
