A Tier 3 Support Engineer at JSI keeps our Nova and 4Sight platforms stable and helps Technical Support and Engineering resolve the hardest issues fast. Nova is our Kubernetes-based platform, built on RKE2, provisioned with Terragrunt/OpenTofu, and running across VMware vSphere and AWS/EKS environments. It uses Flux for GitOps, Grafana and Prometheus for monitoring, and Keycloak for identity. Several of our applications include AI-driven features (LLM and embedding services) for intelligent search and automation. Tier 3 sits between Technical Support and Engineering: Technical Support escalates hard issues to Tier 3, and Tier 3 escalates confirmed code defects to Engineering.
