Troubleshoot defects identified during testing and deployment.

Maintain test results, evidence, logs, and technical findings.

Support customer acceptance and technical sign‑off.

Cloud, Virtualization & Infrastructure

Deploy and support SDM/Core Network functions in bare‑metal, virtualized, and cloud‑native environments.

Work with VNF/CNF deployments.

Hands‑on exposure to OpenStack, Kubernetes, and VMware.

Support deployment, configuration, scaling, networking, connectivity, and troubleshooting.

Work with infrastructure/cloud teams to resolve platform‑related issues.
