Solution Integration and Deployment:

• Perform end-to-end integration of IMS nodes (e. g., CSCF, SBC, TAS, DNS/ENUM).
• Execute installation, configuration, and commissioning of IMS solutions.
• Preparation of delivery-specific MOPs and execution of Live node Activities.
• Ensure alignment with design documents, HLD/LLD, and customer requirements.

Testing and Validation:

• Conduct system integration testing (SIT), interoperability testing (IOT), and user acceptance testing (UAT).
• Validate VoLTE, VoWiFi, and other IMS-based services.
• Troubleshoot integration issues and ensure defect resolution.

Network Configuration and Optimisation:

• Configure SIP protocols, routing, and call flows.
• Optimise IMS network performance and ensure KPI adherence.
• Support parameter tuning and capacity management.

Troubleshooting and Support:

• Analyse logs, traces, and signalling flows (SIP/DIAMETER).
• Identify root causes and implement corrective actions.
• Provide L2/L3 support during deployment and post-integration phases.

Collaboration and Stakeholder Management:

• Work closely with solution architects, design teams, and customers.
• Coordinate with cross-functional teams (Cloud, PACO, Transport).
