RF Engineer Team Lead – North Region

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.

1. 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.

2. 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.

3. 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).

4. 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.

5. 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.

6. 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

• 7+ years in RAN optimization (2G/3G/4G/5G).
• Strong KPI understanding: CSSR, CDR, HOSR, throughput, latency, interference, congestion.
• Proficiency with ENIQ, SmartCare, TEMS, Nemo, Actix, Azenqos, MapInfo, etc.
• Strong knowledge of parameter tuning, PCI/PSC planning, and antenna/RF fundamentals.
•  

Leadership & Soft Skills

• Team lead or senior engineer experience.
• Strong communication and cross‑functional coordination.
• Able to manage customer escalations and high‑pressure situations.
• Analytical, decisive, with strong problem‑solving skills.

Preferred

• Experience with AIS/True/DTAC networks or Ericsson/Nokia systems.
• Familiarity with North Region topology and customer behavior.
• Experience with data analytics or automation tools (Excel macro, Tableau, Python)
