Join our Team About this opportunity: Own the architecture, technical planning, and delivery of IMS LCM scopes for telecom operators. Lead end-to-end lifecycle activities—from upgrades and patches to expansions, migrations, hardware replacements, maintenance, and decommissioning—while protecting service continuity and providing technical leadership across SDU and SDH teams. What you will do:
• Own technical design and execution for IMS nodes, including CSCF, TAS, SBC, MRF, DNS/ENUM, and HSS.
• Ensure solutions align with HLD/LLD, customer requirements, CPI, and 3GPP standards.
• Prepare and review NIRs, MOPs, upgrade, rollback, and contingency plans.
• Lead live-network LCM activities, upgrades, testing, acceptance, and handover.
• Validate VoLTE, VoWiFi, SIP/Diameter signaling, call flows, configurations, and KPIs.
• Troubleshoot complex IMS issues, perform RCA/CAPA, and provide L2/L3 support.
• Act as the technical contact for customers and coordinate with Cloud, PACO, Transport, and vendor teams.
• Track plans, risks, milestones, and technical documentation in JIRA/DSF.
• Support effort estimation, capacity planning, mentoring, and knowledge sharing. The skills you bring:
• 10+ years of telecom experience with hands-on IMS LCM, upgrades, migrations, and live-network activities.




• Strong knowledge of IMS architecture: CSCF, TAS, SBC, MRF, DNS/ENUM, and HSS.
• Expertise in SIP, SDP, Diameter, RTP, VoLTE, VoWiFi, EPC/5GC, and 3GPP standards.
• Experience in IMS troubleshooting, signaling analysis, RCA, KPI monitoring, and tools such as Wireshark.
• Working knowledge of Linux/Unix, Kubernetes, OpenStack, Docker, NFV/SDN, and cloud-native environments.

• Strong customer communication, stakeholder management, leadership, and problem-solving skills.
• Experience working in multi-vendor telecom environments.
• IMS/VoLTE or vendor product certifications.
• Kubernetes, OpenStack, AWS/Azure, Linux, Wireshark, or ITIL certification.
• Experience mentoring engineers and leading cross-functional technical teams.
• Secure and successful IMS upgrades and lifecycle activities.
• Service continuity with minimal network impact.
• Timely troubleshooting and resolution of technical issues.
• Accurate technical documentation, configurations, and handover. “All academic credentials must be from recognized and accredited institutions and are further subject to verification.”
