Senior IMS Solution Integrator

Key Responsibilities

• Perform end-to-end integration of IMS nodes like CSCF, SBC, TAS, and DNS/ENUM, ensuring alignment with design documents, HLD/LLD, and customer requirements.
• Execute installation, configuration, and commissioning of IMS solutions, including preparation of delivery-specific MOPs and execution of live node activities.
• Conduct system integration testing (SIT), interoperability testing (IOT), and user acceptance testing (UAT) to validate VoLTE, VoWiFi, and other IMS-based services.
• Troubleshoot integration issues, analyze logs, traces, and signaling flows (SIP/DIAMETER), and implement corrective actions to ensure defect resolution.
• Configure SIP protocols, routing, and call flows to optimize IMS network performance and ensure adherence to key performance indicators (KPIs).
• Collaborate with solution architects, design teams, and cross-functional teams (Cloud, PACO, Transport) to support customer discussions and technical workshops.
• Prepare integration plans, test reports, and acceptance documents, maintaining knowledge repositories and standard operating procedures.
• Provide L2/L3 support during deployment and post-integration phases, ensuring timely issue resolution and customer satisfaction.
