5G RAN System Verification Engineer

About the Opportunity

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. Reliability earns trust. 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.

What will you do

• Drive end-to-end system-level verification of 5G RAN technologies to secure release readiness.
• 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.
• Troubleshooting system behaviour, performance, throughput, latency, resource load and QoS/QoE indicators for complex issues by analysing logs, traces, KPIs across multiple protocol layers (PHY, MAC, RLC, PDCP, IP).
• 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.
• Collaborate closely with RAN development, integration/CI and product management teams.
• Continuously develop competence in relevant technical domains and modern verification practices. Apply AI-assisted verification methods.

What you will bring

• Bachelor’s or Master’s degree in Computer Engineering, Computer Science, Electrical Engineering or equivalent.
• 2 to 4 years of hands‑on experience in system‑level verification, configuring, deploying, and troubleshooting LTE/5G NR baseband and radio equipment.
• Strong understanding of wireless communication systems (LTE/5G NR), RAN architecture/protocol stack and 5G NR air-interface technologies
• Demonstrated experience analysing and troubleshooting performance issues at PHY/MAC layer.
