Department: Design, Planning & Optimization (DPO)

Location: North Region (Thailand)

Role Summary

Lead the North Region RF Engineering team to ensure end‑to‑end network performance, superior customer experience, KPI achievement, and continuous improvement across 2G/3G/4G/5G RAN. The role focuses on customer satisfaction (NPS, churn reduction), complaint handling, black/white cell improvement, interference management, and performance optimization.

Key Responsibilities

• End‑to‑End Performance & Customer Experience

• Monitor daily/weekly RAN KPIs and ensure SLA achievement.

• Improve customer experience for NPS, churn drivers, and complaint hotspots.

• Lead investigation and resolution of VIP and high‑impact customer complaints.

• Network Optimization & Problem Management

• Manage problematic clusters, black cells, white spots, and worst cells.

• Conduct root‑cause analysis and apply optimization actions for coverage, capacity, mobility, and interference issues.

• Identify internal/external interference and lead interference hunting activities.

• Perform parameter consistency checks and correct deviations.

• RAN Features, Software & Mobility Strategy

• Plan and deploy RAN features across LTE/NR and ensure performance benefits.

• Support software upgrade activities, in-band upgrades, and post‑upgrade tuning.

• Optimize mobility strategy (HO parameters, layer steering, load balancing).

• Field Testing & Benchmarking

• Lead drive test, walk test, NBTC compliance, and benchmarking activities.

• Manage event performance support - concerts, festivals, stadiums - with real‑time monitoring and rapid KPI recovery.

• Provide findings and recommendations with E2E performance review reports.

• Capacity & Quality Management

• Monitor capacity for LTE/NR layers (PRB, CE, DL/UL load, M-MIMO) and propose expansions or configurations (add sector, small cells, TDD config).

• Improve coverage and throughput through antenna optimization and parameter tuning.

• Governance & Acceptance

• Review and approve PAC/FAC/SSOA for new sites, expansions, relocations.

• Ensure network design quality aligns with optimization requirements before acceptance.

• Maintain reporting accuracy and documentation standards.

Qualifications

Technical Skills
