Key Responsibilities

  • Engineer and maintain IMS core network components, with a focus on Ericsson architecture (CSCF, HSS, TAS, MRF, SBC).
  • Rapidly adapt to Nokia IMS platforms (Cloud Native Communication Suite, TAS, CFX, SBC, MRF).
  • Lead planning and execution of large-scale live core network migrations, including vendor swaps, rollback strategies, and cutover procedures.
  • Support and troubleshoot 4G/5G voice services including VoLTE, VoNR, VoWiFi, and RCS.
  • Design and secure IP networks using BGP, OSPF, QoS, VPNs, and SBCs (Ribbon, Metaswitch).
