We are #VLteam – tech enthusiasts constantly striving for growth. The team is our foundation, that’s why we care the most about the friendly atmosphere, a lot of self-development opportunities and good working conditions. Trust and autonomy are two essential qualities that drive our performance. We simply believe in the idea of ​​“measuring outcomes, not hours”. Join us & see for yourself!

About the role

We’re looking for a Full-Stack Engineer who moves confidently across both frontend and backend — fluent in TypeScript, comfortable in Node.js internals, and curious about tooling beyond the usual stack. This isn’t just a UI-heavy role with a backend tacked on. You’ll contribute meaningfully to frontend architecture and performance, while also digging into backend challenges involving gRPC, cryptography, Electron, and efficient service design.

It’s a good fit if you think in systems, care about how things run under the hood, and value maintainability as much as feature velocity.
