Job Description

About this opportunity:

We are currently seeking a talented and dedicated individual to join our Ericsson team as a Technical Authority Expert. This critical role belongs to our Managed Services department, directly contributing to our ongoing Ericsson Operations Engineer projects. You will be at the forefront of tech-driven change, offering your specialist knowledge to guide the entire lifecycle of our projects. Whether we are in the Create, Sustain, or Evolve stages, your expertise will pave the way forward in your domain.

What you will do:

Provide Level 2/L3 support for RAN issues in a multi-vendor environment (Huawei and Ericsson). Monitor and troubleshoot 2G/3G/4G/5G RAN network alarms and performance degradation. Handle critical network outages and support field teams for fault isolation and resolution. Perform cell-level diagnosis, KPI degradation analysis, and coordinate corrective actions. Support post-integration and commissioning activities of sites and technologies. Implement RAN parameter changes, neighbor list updates, and site-level configurations remotely. Analyze KPIs (e.g., CSSR, DCR, HOSR, Throughput, UL/DL utilization) and suggest optimization. Support in RNO activities such as drive test log analysis, PCI/PSC/BSIC planning, and handover tuning. Participate in planned activities (software upgrades, parameter audits, RAN swaps) ensuring minimal impact. Raise and manage MOPs for configuration changes or troubleshooting activities. Coordinate with vendors and field teams for successful execution of changes and issue resolution. Prepare daily/weekly performance reports, RCA documentation, and trouble tickets. Maintain logs of parameter changes, outage history, and RAN configuration audit trails

The skills you bring:

Strong knowledge of Huawei BTS3900/eNodeB/gNodeB and Ericsson RBS/eNB/gNB platforms. Hands-on experience with Huawei M2000, U2020, NetEco, and Ericsson OSS/RNCS/RAN tools. Familiar with LTE/NR architecture, Layer 1/2/3 concepts, S1/X2 interfaces, and VoLTE fundamentals.
