- Hands on on ESM.

Monitoring & Troubleshooting

- Integrate Prometheus/Grafana, EFK/ELK or Loki for observability.
- Use kubectl, ceph, and Linux tools for troubleshooting nodes, pods, storage, and networking.
- Analyse CNF behaviour during failures and generate RCA documentation.
- Use Netcool & OMC for monitoring.

Required Skills & Experience:

- 6-12 years of experience in cloud-native infrastructure or telco platforms.
- Solid hands-on in Kubernetes (certifications like CKA/CNCF preferred).
- Expertise in:
- CNIs (Multus, Calico, SR-IOV)
- Storage (Rook/Ceph, CSI)
- Linux (RHEL/CentOS/Ubuntu)
- Networking (L2/L3, BGP, VLAN, IPAM, Juniper/Extreme Switches)

- Experience with:

- Helm, YAML, Git

- Ericsson tools: ENM, CENX, EO-EVNFM, OMC & ESM.
- Familiarity with Ericsson CNIS framework is strongly preferred.
