Jobbeschreibung

Design and build the interface where companies manage their agent-first source of truth.

We're building the self-maintaining source of truth for the AI-native company, the context repository that keeps company knowledge structured, up-to-date, permission-aware, and ready for every AI agent.

That takes people who are exceptionally talented, obsessed by the vision, and set on doing the best work of their lives. If that's you, read on.

The Opportunity

You'll own the core product experience of Qontext: the interface where companies decide what their AI is allowed to know, and how it stays true over time.

You'll turn deep backend logic, a graph-based, versioned, governed context repository, into product that feels effortless. From Access controls that define what each Client can reach, to the Change reviews where humans validate and refine context, you'll build the surface that the entire AI-native company runs on.

We're already live with 15+ design partners and launching v1 in Q3 2026. This is the rare moment where the product, the architecture, and the category are still yours to shape. We think of Qontext as a once-in-a-lifetime opportunity, and we hire people who feel the same.
