Role overview

CAST AI is seeking a skilled senior software engineer with deep expertise in databases. It's more about understanding database underlying technology than just knowing how to use it.

• ClickHouse and PostgreSQL for business metrics
• GRPC and REST APIs
• GitLab CI with ArgoCD as our GitOps CD engine
• Prometheus, Grafana, Loki, and Tempo for observability
• Deployment charts are written in Helm.

Experience with everything mentioned is not a strict prerequisite for the ideal candidate, but it does offer a competitive edge.
