Sr. Automation Test Engineer

GAVS Technologies; Chennai; On-site; INR 900,000 - 2,400,000; Full time

Job summary

GAVS Technologies is seeking a qualified 5G Test Automation Engineer to design, develop, and maintain automated test suites for 5G cloud-native network functions. The role focuses on validating SCP, NRF, PCF, and PCRF interactions using Python, Tcl, or Robot Framework within Kubernetes/OpenShift environments.

You will build robust test pipelines, verify HTTP/2, REST, JSON/YAML protocols, and Diameter interfaces, and contribute to observability with Prometheus, Grafana, and OpenSearch.

Qualifications

• 5–10 years of relevant automation testing experience in telecom/5G.
• Strong scripting experience in Python and Tcl, with exposure to test frameworks like Robot Framework.
• Experience building automated test pipelines and using Gherkin syntax.

Responsibilities

• Design, develop, and maintain automated test suites from scratch for 5G cloud-native network functions.
• Build and maintain automated test pipelines using Gherkin syntax and PCWEB.
• Execute automated validation for SBA flows across 5G Core functions (SCP, NRF, PCF).
• Validate 5G control plane protocols (HTTP/2, REST APIs, JSON/YAML) and 4G Diameter interfaces (Gx, Gy, Rx, Sd, Sy).
• Automate end-to-end testing of SCP routing, delegated discovery, and NRF profile registration/heartbeats.
• Develop chaos and failover tests for resiliency and HA in a CUPS environment.
• Script load, capacity, and stress tests to monitor CPU trends and signaling limits.
• Deploy and run test frameworks inside Kubernetes and OpenShift clusters.
• Integrate scripts with Prometheus, Grafana, and OpenSearch for observability and KPI tracking.

Job description

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.
