Radio Frequency Optimization Engineer (LTE/5G)

About the role

The RF Optimization Engineer monitors, analyzes and improves radio network performance, mainly on LTE with involvement in 5G optimization. The role covers coverage quality, service reliability, capacity utilization and customer experience.

Key responsibilities

• Analyze network KPIs such as accessibility, retainability, mobility, throughput, radio quality and resource utilization to identify and prioritize performance issues.
• Investigate root causes using BTS counters, alarms, configuration data, drive test results and UE logs, ensuring data accuracy and KPI consistency.
• Audit and optimize radio parameters such as idle mode mobility, handovers, neighbor relations, load balancing and Carrier Aggregation.
• Investigate coverage gaps, interference, overshooting and congestion, and recommend parameter changes, physical optimization or capacity improvements.
• Investigate complaints escalated by Customer Care, distinguish network-related issues from UE capability or configuration problems, and follow corrective actions to verified resolution.
• Collaborate with RF Planning on PCI, PRACH, frequency and other planning revisions, and coordinate with Operations, Core and IP/Transmission on end-to-end service issues.
• Support LTE/5G feature trials and assess performance after carrier additions, software upgrades and network changes.
• Prepare and implement approved optimization actions with clear objectives and rollback criteria, validate results with before/after comparisons, and document findings and regular performance reports.

Required profile

• Bachelor's degree in Telecommunications, Electrical or Electronics Engineering or a related discipline.
• Fresh graduates: strong wireless communications and LTE/5G fundamentals, analytical ability and willingness to learn; internships, projects or training are an advantage.
• Experienced candidates: preferably two or more years of RF optimization or RAN performance experience with practical troubleshooting and KPI improvement skills.
• Good communication, teamwork, problem-solving and reporting skills, and willingness to support field investigations.
• Proficiency in Kurdish, Arabic and English.

Required skills

• Understanding of LTE/5G architecture, radio procedures and their impact on user experience; knowledge of 5G NR SA/NSA is an advantage.
• Familiarity with performance tools and drive test or UE log analysis; practical proficiency expected from experienced candidates.
• Experience with Nokia radio networks, parameters and counters is an advantage.
• Good Microsoft Excel skills and Word and PowerPoint proficiency; Python or Power BI knowledge is an advantage.
