SI/SSI IMS

Role Overview The Solution Integrator IMS is responsible for end-to-end integration, configuration, testing, and deployment of IMS solutions within telecom networks. The role ensures seamless interoperability of IMS components across multi-vendor environments while maintaining high service quality and reliability. Key Responsibilities 1. Solution Integration & DeploymentPerform 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.2. Testing & ValidationConduct 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.3. Network Configuration & OptimizationConfigure SIP protocols, routing, and call flows.Optimize IMS network performance and ensure KPI adherence.Support parameter tuning and capacity management.4. Troubleshooting & SupportAnalyse logs, traces, and signalling flows (SIP/DIAMETER).Identify root causes and implement corrective actions.Provide L2/L3 support during deployment and post-integration phases.5. Collaboration & Stakeholder ManagementWork closely with solution architects, design teams, and customers.Coordinate with cross-functional teams (Cloud, PACO, Transport).Support customer discussions and technical workshops.6. Documentation & ReportingPrepare integration plans, test reports, and acceptance documents.Maintain knowledge repositories and standard operating procedures. Technical Skills Required Skills & Competencies Strong understanding of IMS architecture and 3GPP standards.Hands-on experience with:SIP, SDP, DIAMETER protocolsVoLTE / VoWiFi servicesLinux/Unix systemsKnowledge of telecom nodes such as CSCF, TAS, SBC, DNS.Familiarity with packet core (EPC/5GC) and signalling flows. Tools & Technologies Wireshark / signalling analysers.Scripting (Python/Shell) is an advantage.Cloud/Virtualization (NFV/SDN) exposure preferred.Docker and Kubernetes knowledge with exposure to Cloud Native solutions. Experience & Qualifications Bachelor's degree in Electronics, Telecommunications, or related field.Typically, 38 years of experience in telecom core/IMS integration.Experience working in multi-vendor environments is preferred. Behavioural Competencies Strong analytical and problem-solving skillsCustomer-centric approachAbility to work under pressure and meet tight deadlinesEffective communication and teamwork Preferred Certifications IMS / VoLTE certificationsLinux or cloud certifications (e.g., OpenStack, Kubernetes)Ericsson internal certifications (if applicable) Key Deliverables Successful IMS integration and service rolloutHigh-quality testing and defect-free deploymentsTimely issue resolution and customer satisfaction Skills Required Docker, Shell, Scripting, Kubernetes, Diameter, Sdn, Sdp, Nfv, Dns, SBC, Epc, Volte, CSCF, Packet Core, TAS, Linux, Wireshark, Sip, Unix, Python Role Overview The Solution Integrator IMS is responsible for end-to-end integration, configuration, testing, and deployment of IMS solutions within telecom networks.
