Job description

About this 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.

The Opportunity

Reliability earns trust. As part of our RAN System Verification team, you will work in advanced lab environments to 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 validate system behaviour under high‑load traffic scenarios, ensure that capacity and performance targets are met, and influence release decisions across our global product portfolio.

What you will do

• Provide technical leadership for end-to-end system verification of 5G features, shaping verification priorities from feature readiness to release in alignment with business strategy and customer outcomes
• Act as a technical specialist in system performance analysis using logs, traces, and KPIs such as throughput, latency, resource utilization, and QoS/QoE indicators to identify systemic bottlenecks and drive product-level improvements.
• Lead complex, cross-layer investigations across PHY, MAC, RLC, PDCP, and IP, applying advanced root-cause analysis to resolve complex performance and capacity issues.
• Perform requirement analysis for feature integration and verification to ensure alignment with customer expectations and network performance objectives.
• 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.
• Establish verification methodologies and quality standards that represent live network scenarios and provide coverage for performance, capacity, Stability and customer experience.
• Provide technical direction, coaching, and mentorship to verification engineers and contribute to the development of organizational competence in modern (AI) system verification practices.
• Drive continuous improvement of products, verification frameworks, test coverage, automation, CI/CD pipelines, and AI-assisted verification practices, improving efficiency, quality, and time to market.
• Lead collaboration across RAN development, integration/CI, product management and other stakeholders organization to resolve issues and secure high-quality deliveries.
• Lead customer trials and field issue reproduction, move quickly from symptoms to root cause and provide clear defect reports with actionable next steps.

The Skills You Bring

• Bachelor’s or Master’s in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience.
• 8 - 12+ years of hands‑on experience in system-level verification, deployment, integration, and troubleshooting of LTE/5G NR baseband and radio systems, including demonstrated technical leadership.
• Strong understanding of wireless communication systems (LTE/5G NR), RAN architecture and protocol stack, and 5G NR air‑interface technologies.
• Demonstrated experience analyzing and troubleshooting performance issues at PHY/MAC layer, including link curve verification, channel-quality assessment, and evaluation under diverse and adverse channel conditions.
• Deep expertise of system level KPIs (throughput, latency, resource load, QoS/QoE) and the ability to identify performance bottlenecks.
• Experience working with Channel emulators, fading technologies, traffic generation and test tools (for example UE simulators, Viavi, real UEs).
• Advanced Linux skills and solid knowledge of IP routing, switching, and networking.
• Demonstrated success in influencing product, architecture, and release decisions through data-driven verification insights and technical judgment.
• Programming, automation, and scripting skills (for example Python, Bash, Java) and solid understanding of CI/CD concepts.
• Experience with configuration management and automation tools (for example Git, Gerrit, Jenkins) in a modern development and integration environment.
