Telecom Test Engineer or Network Test Automation Engineer focused on 4G/5G network validation and performance testing. Here's a refined summary of what the role is about:

Position Overview:

• This role involves testing and validating telecom network infrastructure and services, particularly in the 4G and 5G domains.
• The engineer will work with industry-standard testing tools (e.g., Landslide, Spirent, IxLoad), simulate complex call flows, and ensure conformance to 3GPP specifications.
• The responsibilities include traffic generation, protocol testing, system monitoring, and automation of test scenarios to evaluate performance and scalability.

Key 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.
• Use scripting or programming to automate system and tool operations.
• Collaborate cross-functionally with multiple teams for test planning, execution, issue resolution, and project delivery.

Ideal Candidate Profile:

• Strong hands-on experience with telecom test tools and traffic generators.
• In-depth knowledge of mobile network architecture (4G/5G).
• Comfortable working in a multi-team, collaborative environment with some project management or coordination responsibilities.
• Capable of both manual and automated test execution, with solid scripting skills for automation.
