## Solution Test EngineerBangalore,Karnataka,IndiaFind out how well you match with this jobJob ID: 787185## Join our Team**About the Opportunity:**At Ericsson, we're shaping the future of connectivity through cutting-edge 5G and cloud-native technologies. We're looking for a Solution Test Engineer to lead end-to-end testing, system integration, automation, and validation of Ericsson Private 5G solutions ( BEWS - Private Networks). In this role, you'll work across 5G Core, RAN, Kubernetes, and cloud-native platforms, drive quality through automation and CI/CD, troubleshoot complex network issues, and collaborate with global teams to deliver world-class telecom solutions.**What You Will Do**• Test Design & Execution: Design and execute detailed E2E system test plans for Ericsson Private 5G (EP5G) solutions, ensuring full coverage of 3GPP features and customer use cases. • System Integration: Integrate and validate 5G components, including Cloud-Native Core (cn5GC), RAN, and Management/Orchestration platforms, ensuring seamless interoperability. • Advanced Validation: Own the E2E validation for specific feature sets across performance, scaling, and stability, utilizing CI/CD pipelines for automated regression. • Protocol Debugging: Perform deep-dive troubleshooting of complex call flows using tools like Wireshark/QXDM to analyze NAS/AS signaling and interfaces (N1, N2, N3, etc.). • Automation Development: Develop and maintain automated test scripts within a Python/Robot Framework environment to increase test velocity and reliability. • Stability & Performance Testing: Design and run soak tests, stress tests, and load models to identify memory leaks and system bottlenecks before deployment. • Mentorship: Provide technical guidance to junior engineers, conduct peer reviews of test cases, and contribute to the team's internal knowledge base.**Skills You Bring**Bachelor’s/Master’s in CS, EE, or related field with 6–8 years of experience in Telecom/Network testing. 5G/4G Domain Knowledge: Strong understanding of 3GPP architectures and protocols (NGAP, S1AP, RRC, HTTP/2). Ability to analyze multi-interface traces to isolate faults. Cloud-Native Skills: Hands-on experience with Kubernetes (K8s), Docker, and Helm. Understanding of K8s networking (Services, Load Balancers, and CNI basics) is essential. Networking Foundations: Solid knowledge of L2/L3 networking, including IPV4/V6, VLANs, Routing, and familiarity with OSPF/BGP. Automation Proficiency: Strong Python scripting skills and experience with Robot Framework (or similar) to automate complex system-level scenarios. System Validation Expertise: Proven ability to design test cases for performance (throughput/latency), scaling, and stability (soak/reliability). Infrastructure & Tools: Proficiency in Linux/Unix environments. Experience with industry tools such as Spirent (Landslide), Keysight, or Viavi.**“All academic credentials must be from recognized and accredited institutions and are further subject to verification.”**
