At Ericsson, we are the world leader in 5G innovation and deployment, powering a connected future where technology improves the way we live and work. With unmatched expertise and market penetration in 5G New Radio (NR), we are shaping the future of communication and pioneering advancements that will lead us into the era of 6G.

As part of our RAN System Verification team, you will verify, troubleshoot and deliver Ericsson's 5G New Radio (NR) solutions on high-performance General Purpose Processors (GPP), with sharp focus on performance, scalability and quality. You will work in advanced lab environments to validate system behaviour under realistic and extreme traffic conditions, influencing release readiness and overall product quality.

Perform capacity and performance verification of RAN systems under high-load traffic scenarios comprising Max supported UEs per cell/DU, throughput (DL/UL), control plane capacity and mobility under load.

Analyse system behaviour and performance using logs, traces, KPIs including throughput, latency, PRB utilisation, resource load and QoS/QoE indicators.

Troubleshooting Link curve verification, Channel quality and perform root cause analysis across multiple protocol layers (PHY, MAC, RLC, PDCP, IP) for complex system issues.

Perform requirement analysis for feature integration and verification to ensure alignment with customer expectations.

Contribute to continuous improvements of products, test coverage, verification frameworks, automation and CI/CD pipelines.
