Senior Software Engineer Core Database

Kurrent provides an event-native data platform that feeds real-time, business-critical data with historical context in fine-grained streams from origination to destination, enhancing data analytics and AI outcomes.

We currently have developers in the UK, the US, the Netherlands, Mauritius, Norway and Cyprus.

KurrentDB is our source-available database at the core of the Kurrent Platform. With strong durability and consistency guarantees it immutably captures every event, making it easy to write, read, subscribe, and replay event streams in real time. Built for distributed systems, it stores, distributes, and indexes events efficiently, so teams can build fast, reliable services on a durable event log. KurrentDB also includes built-in JavaScript event processing, enabling lightweight projections, transformations, and workflows directly alongside the data.
