Senior Software Engineer (TS & JavaKotlin) AI DevTools

About Zencoder

Zencoder is building the next generation of AI coding agents — advanced tools that supercharge developer workflows and elevate engineering impact. Our mission is to transform how software is built by equipping developers with AIpowered tools that boost productivity, improve code quality, and unlock creativity.

Our product integrates seamlessly with JetBrains IDEs and VS Code, helping developers generate, refactor, and repair code. It includes fast and intelligent AI code completion, and our agents can independently perform tasks like running shell commands or searching the web to assist with coding and debugging. Were especially proud of our proprietary Repo Grokking™ technology, which enables our AI agents to deeply understand your entire codebase, providing the strongest contextual understanding on the market. Zencoder also connects with 20+ popular tools like Jira, Sentry, GitHub, and GitLab, making it the most integrated AI coding solution available.

This is just a small part of what Zencoder is all about. There’s much more to discover — and we’re just getting started.
