Sr. Automation Test Engineer

5G Test Automation Role (PCRF/PCF/SCP/NRF)

Experience: 5 \- 10 years

Automation Scripting: Design, develop, and maintain automated test suites from scratch using Python, Tcl/iTcl, or Robot Framework to validate 5G cloud\-native Network Functions.

Framework Management: Build and maintain automated test pipelines using Gherkin syntax, PCWEB, or similar test tools, ensuring strict execution of regression and stability pools.

5G Architecture Testing: Execute automated validation for Service\-Based Architecture (SBA) flows across 5G Core functions including SCP, NRF, PCF, and 4G PCRF.

Signaling \& Protocol Verification: Validate 5G control plane protocols (HTTP/2, REST APIs, JSON/YAML) and 4G Diameter interfaces (Gx, Gy, Rx, Sd, Sy) through automated signaling scripts.

Call Flow \& Routing Automation: Automate the end\-to\-end testing of SCP routing rules, delegated discovery, Model\-C/D communication, and NRF profile registration/heartbeats.

Resiliency \& HA Validation: Develop automated chaos and failover test cases to evaluate pod failures, ungraceful terminations, and interface switchovers in a CUPS environment.

Performance \& Capacity Benchmarking: Script automated load, capacity, and stress tests to monitor CPU trends, maximum signaling limits, and maximum simultaneous PDU sessions.

Cloud\-Native Integration: Deploy and execute test automation frameworks natively inside containerized Kubernetes and OpenShift cluster environments.

Observability Tracking: Integrate automated scripts with observability tools like Prometheus, Grafana, and OpenSearch to track real\-time application metrics and KPI synchronization.
