Backend Engineer
Qontext, Berlin
The role
You'll architect and build the core of the context repository: the database, the versioning, and the retrieval that let AI agents reach correct, permission-aware company knowledge in real time.
This is deep backend work. You'll own the systems that keep context consistent and trustworthy at scale, from File versions and Change reviews to Automatic Change Reconciliation, and the Sync infrastructure that keeps the context repository up to date.
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.
What you will do
- Design the data model and database systems at the core of the context repository
- Build versioning, change reviews, and automatic change reconciliation that keep context consistent and auditable
