Main activities and tasks:

1. Network Planning & Design

• Plan and design RAN (2G/4G/5G) networks, ensuring optimal coverage, capacity, and performance in alignment with business and customer requirements.
• Develop and validate RAN topology, frequency, and parameter plans.

2. Solution Implementation & Change Support

• Support the implementation of solutions and changes initiated by client related to RAN network.
• Prepare technical design documents and validate implementation feasibility.
• Collaborate with operations, optimization, and field teams to ensure seamless deployment of changes.

3. Software and Feature Rollout

• Manage and coordinate RAN software and feature rollout in collaboration with vendor (Ericsson) and internal stakeholders.
• Evaluate new features, conduct impact analysis, and validate post-rollout performance.

4. Operation on Production Nodes

• Perform configuration, parameter tuning, and troubleshooting directly on live production nodes while ensuring network stability and minimal customer impact.
• Ensure strict adherence to change management and rollback procedures.

5. Inventory Data Management

• Manage Inventory data and ensure consistency across all related systems (ENM, OSS, Configuration Management databases, etc.).
• Validate data accuracy for integration, audit, and performance purposes.

6. Performance Monitoring & Optimization

• Continuously monitor RAN KPIs, identify degradations, and execute corrective actions.
• Perform root cause analysis (RCA) of performance issues and implement optimization measures.
• Support interference detection and mitigation using advanced tools and methodologies.

7. Incident & Change Request (CR) Handling

• Provide technical support and coordination during incidents and network outages affecting RAN performance.
• Manage and review Change Requests (CRs) related to RAN design, implementation, and parameter updates.

9. Customer & Event Support

• Provide customer complaint investigation and resolution support related to RAN quality and performance.
• Lead Public Event Assurance activities, including capacity planning, pre-event testing, and live monitoring.

10. Cross-Functional Collaboration

• Work closely with Core, Transmission, and OSS teams to ensure end-to-end network quality.
• Interface with vendors (Ericsson) and partners for feature introduction, issue resolution, and performance improvement initiatives.
