In this vital technical role, you will design, deploy, configure, integrate, and optimize complex P-CSCF, I-CSCF, and S-CSCF network elements, ensuring uncompromised session routing, voice quality, and high availability across distributed cloud environments.

Bringing 5+ years of progressive professional hands‑on experience in telecommunications core engineering, you will empower Tier‑1 mobile network operators to achieve superior signaling reliability, low‑latency call establishment, and resilient communication workflows. This prestigious career opportunity offers competitive remuneration, high executive visibility, and professional growth within a premier global IT consulting and executive recruitment enterprise.

As an IMS CSCF Engineer supporting Comp Nova on a remote basis across the USA and Canada, you will take full operational, tactical, and technical ownership of core SIP signaling, IMS registration flows, interoperability testing, and network performance tuning. Your day‑to‑day responsibilities include configuring Call Session Control Functions, managing Diameter and SIP interfaces, troubleshooting voice call drop anomalies, collaborating with cross‑functional core engineering squads, and interacting directly with technical recruitment leaders like Salwan Singh.

• Architect, deploy, configure, test, and maintain enterprise‑grade IMS P-CSCF, I-CSCF, and S-CSCF network elements.
• Analyze, troubleshoot, and optimize SIP signaling, registration, call setup, and teardown flows across IP networks.
• Integrate CSCF platforms with Home Subscriber Servers (HSS), User Data Management (UDM), and Application Servers.
• Execute rigorous interoperability testing (IOT) and end‑to‑end voice over LTE (VoLTE) and 5G voice (VoNR) service validation.
• Monitor core network performance metrics, traffic counters, and signaling latency to preempt operational bottlenecks.
• Conduct root‑cause analysis (RCA) and incident remediation for complex signaling failures and session drops.
• Collaborate seamlessly with multi‑vendor engineering squads, NOC teams, and client project stakeholders during deployment cycles.
• Maintain meticulous technical documentation, network architecture diagrams, routing policies, and configuration audit logs.

• Bachelor’s degree in Telecommunications Engineering, Electrical Engineering, Computer Science, or related technical discipline.
• Minimum of 5+ years of progressive professional hands‑on experience in telecom core networks and IMS CSCF engineering.
• Strong, demonstrable operational expertise in SIP, SDP, Diameter, RTP, and SIGTRAN protocols.
• Comprehensive working knowledge and practical proficiency in Nokia, Ericsson, or Huawei IMS core architectures.
• Deep practical experience in real‑time network troubleshooting, packet analysis, and signaling trace inspection (Wireshark, TShark).
• Solid practical grasp of cloud‑native deployment models, containerization, and virtualized network functions (VNFs/CNFs).
• Exceptional analytical problem‑solving aptitude, crisis management skills, and professional communication capabilities.
• Mandatory legal work authorization and physical availability for remote professional operations in the USA or Canada (C2C, W2, or IC eligible).

• Professional vendor certifications such as Nokia Certified Telecommunications Engineer or Cisco Certified Network…
