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.

What You Will Do

  • Infrastructure: Build and scale multi-region Kubernetes infrastructure (EKS/GKE) for five-nines workloads.

  • Architecture: Architect active-active distributed systems (Kafka, CockroachDB/YugabyteDB, Redis).

  • GitOps: Implement Terraform, Helm, and GitOps (Flux/ArgoCD) across cloud and hybrid environments.

  • Resiliency: Own DR, failover, backup/restore, and multi-region resiliency.

  • Security: Drive zero-trust security, identity, multi-tenant isolation, and cryptographic audit trails.

  • Observability: Build and maintain stacks using Prometheus, Grafana, and OTEL.

  • AI-SRE: Lead AI-driven automation (auto-remediation, incident insights, AI-based root cause analysis).

  • Deployment: Support on-prem/air-gapped deployments and legacy integrations.

Essential Skills

  • Deep Kubernetes (EKS/GKE; operators/CRDs a bonus)

  • Terraform (multi-cloud)

  • GitOps (Flux or ArgoCD)

  • Kafka / Event streaming

  • Distributed SQL databases (CRDB, YugabyteDB)

  • Prometheus, Grafana, OpenTelemetry

  • Language: Go (AI-accelerated development welcome)
