Description

Design, develop and execute manual and system-level E2E test cases covering RAN (5G NR) and 5G Core (SA) scenarios. Prepare and maintain test plans, test strategies, and test case documentation based on requirements and specifications. Perform detailed call-flow and protocol trace analysis (L3 and signalling) to debug and isolate complex end-to-end issues. Conduct interoperability, performance and KPI validation tests across UE, gNodeB, and 5G Core elements. Use and operate UE simulators (e.g., Viavi, Amarisoft) and other lab test equipment to reproduce and validate issues. Collaborate closely with product teams, software engineers, and field teams to reproduce customer issues and drive defect resolution. Work with cloud-native 5G Core and Kubernetes environments to validate CNF behaviour and deployment scenarios. Contribute to continuous improvement of test processes, tools, and test automation where applicable. Mentor junior engineers and share best practices in test design and debugging. Bachelor's or Master's degree in Computer Science, Engineering, Telecommunications, or related field. 8-10 years of hands-on experience in wireless testing with strong focus on 5G NR end-to-end testing. Deep knowledge of 5G NR SA and LTE technologies and practical experience across RAN and 5G Core. Strong understanding of 3GPP specifications with emphasis on Layer 3 protocols and signalling procedures. Proven expertise in call-flow and protocol trace analysis for debugging complex E2E issues. Hands-on experience with UE simulators such as Viavi and Amarisoft. Experience preparing test plans, test cases and conducting requirement analysis. Working knowledge of cloud-native 5G Core and Kubernetes environments. Familiarity with KPIs and system-level performance validation. Exposure to test automation frameworks and Python scripting. Experience with CI/CD pipelines and container orchestration in test environments.

Responsibilities

Design, develop, and execute manual and system-level end-to-end test cases for 5G scenarios. Collaborate with product teams and engineers to reproduce customer issues and drive defect resolution.
