    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.

    Key Responsibilities

    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)
