About OpenCoreOS
• We're building the first open-source "Thin Ledger", designed to replace legacy core systems with a Golang-based, Protobuf-defined, event-driven platform powered by Kafka, Redis, and multi-region CockroachDB/YugabyteDB.
• Our platform is AI-native from the ground up: autonomous SRE agents, AI-generated runbooks, and everything-as-code—from policies to infrastructure definitions.
• We're mission-critical by default, targeting five-nines uptime and multi-region failover for regulated institutions.
• We work openly and fast, and colocate in Huckletree, Liverpool St, London for in-person collaboration, supported by async-friendly workflows.
