Lead Engineer

Roles and responsibilities

Key Responsibilities:

• Participate in solution integration and deployment for 5G/4G Core systems in cloud-native environments, with a focus on Openstack, Aerospike (NoSQL), and containerized network functions (CNF/VNF).
• Work on operational and configuration aspects of OCS (Online Charging System), PCRF (Policy and Charging Rules Function), DRA (Diameter Routing Agent), and associated call flows.
• Perform troubleshooting, analysis, and problem-solving for 4G/5G core network issues, particularly involving SMF, PCF, NRF, and CHF in 5G, and EPC core in 4G.
• Utilize cloud-native tools such as Docker, Kubernetes, and OpenStack to manage container platforms for network function virtualization.
• Employ monitoring tools like Prometheus, Grafana, and Kibana for system performance analysis and diagnostics in cloud environments.
• Collaborate with cross-functional teams to ensure seamless integration of core network elements with cloud platforms, including AWS/OpenStack.
• Ensure effective deployment and integration of 4G/5G core solutions with strong knowledge of Diameter and HTTP2 protocols.
• Maintain deep technical knowledge of 5G & 4G EPC (Evolved Packet Core) fundamentals and related communication technologies. Provide input for improving system reliability, scalability, and performance in live deployments.

• Cloud & Virtualization**: Experience with cloud platforms such as AWS, OpenStack, and working in virtualized environments (VNF/CNF).

  5G & 4G Fundamentals**: Solid understanding of the fundamentals of 5G and 4G EPC networks, including architecture and data call flow.
