Description

You will lead the execution and automation of performance and functional tests for core network infrastructure. Your work ensures protocols and call flows meet 3GPP standards across 4G EPC, 5G Core, Diameter, SIP (VoLTE, VoNR), and HTTP2 environments.

Responsibilities

• Execute and automate performance and functional tests using Spirent Landslide, Keysight IxLoad, and related tools.
• Validate protocols and call flows for 4G EPC, 5G Core, Diameter, SIP (VoLTE, VoNR), and HTTP2.
• Interpret and apply 3GPP specifications to ensure test cases and network behavior are standards-compliant.
• Perform API validation (REST/SOAP) and basic network troubleshooting (IP, VLANs, subnetting).
• Monitor systems using tools like Grafana and Nagios, and use scripting to automate system operations.

Required Skills

• 8+ years of experience in network testing or quality engineering.
• Proficiency with Spirent Landslide and Keysight IxLoad.
• Strong understanding of 3GPP specifications for 4G EPC and 5G Core.
• Experience validating Diameter, SIP (VoLTE, VoNR), and HTTP2 protocols.
• Ability to perform API validation using REST and SOAP.
• Knowledge of IP networking, VLANs, and subnetting.
• Experience with monitoring tools such as Grafana and Nagios.
• Scripting or programming skills to automate tool operations.

Preferred Skills

• Experience collaborating cross-functionally for test planning and issue resolution.
