About Vibe Kanban
Vibe Kanban is a YC-backed, London-based startup solving human–AI interaction for software developers.

As AI agents become more capable at writing code, developers are spending more of their time planning and reviewing what those agents produce. Vibe Kanban helps them do exactly that, seamlessly integrating with leading coding agents like Anthropic’s Claude Code and OpenAI’s Codex.

Thousands of engineers, from early-stage startups to large regulated enterprises, use Vibe Kanban every day.
We’re a small, talent-dense, and relentlessly driven team.

Key Responsibilities:

• Own significant parts of the backend, from architecture to polish
