Core Responsibilities

Primary Functions

  • Lead end‑to‑end RF planning and design for LTE and 5G NR networks, including link budget calculations, coverage prediction, capacity planning, cell site configuration (PCI/CI), antenna selection, tilt and azimuth optimization, and interference avoidance to meet SLA and KPI targets.
  • Conduct comprehensive site surveys and on‑site verification (including indoor/outdoor and DAS/small cell environments), document findings, and produce detailed technical reports with coverage maps, recommended mitigations, and implementation checklists.
  • Perform drive tests and walk tests using TEMS, Nemo, or equivalent tools to collect KPIs, RSRP/RSRQ/SINR, throughput, handover performance, and call trace data; analyze results and deliver prioritized optimization plans.
  • Design and optimize indoor solutions using tools such as iBwave, including distributed antenna systems (DAS), small cell placements, Wi‑Fi offload strategies, and in‑building capacity modeling to achieve targeted capacity and coverage.
  • Execute frequency planning, spectrum allocation recommendations, and inter‑site interference resolution including neighbor list optimization, ANR tuning, and carrier aggregation strategy for multi‑band deployments.
  • Define and validate RF parameters and radio access network (RAN) configuration changes (e.g., power, antenna patterns, scheduler parameters) to improve KPI performance (accessibility, retainability, integrity, mobility, and throughput).
  • Create detailed RF design packages and Bill of Materials (BOM) for new site builds, upgrades, and technology migrations, including passive and active equipment specifications and cabling/backhaul requirements.
  • Collaborate with backhaul engineers to specify and validate microwave and fiber link budgets, link availability requirements, and QoS constraints for transport networks that support high‑capacity 5G services.
  • Lead acceptance testing and commissioning for new sites and network upgrades: develop test plans, define success criteria, run E2E tests, and log defects through to closure with vendors and field teams.
  • Provide expert troubleshooting for complex RF and RAN issues, including drop call analysis, radio link failures, mobility issues, intermodulation, and external interference sources using spectrum analyzers and protocol analyzers.
  • Perform capacity forecasting and traffic modeling using historical KPI data and demand drivers; recommend capacity upgrades, site splits, or traffic offload strategies (Wi‑Fi, small cells) to prevent congestion.
  • Develop site acquisition input and technical support for permitting, zoning, and tower work including structural and RF feasibility assessments, mast load and clearance considerations.
  • Create and present clear, client‑facing technical deliverables (executive summaries, slide decks, technical appendices) that translate RF findings into business impacts, CAPEX/OPEX estimates, and recommended next steps.
  • Coordinate with vendors (RAN, DAS, small cells, antenna suppliers) and system integrators to manage RF parameter implementation, neighbor relations, and software/hardware upgrades across multi‑vendor environments.
  • Implement and maintain RF network models in planning tools (Atoll, Mentum, Planet) and GIS so that planners and stakeholders can simulate scenarios, analyze "what‑if" plans, and track KPIs over time.
  • Advise on 5G features (massive MIMO, beamforming, dynamic spectrum sharing, network slicing) and their practical impact on coverage, capacity, and device experience; provide migration strategies from LTE to 5G Standalone/NSA.
  • Lead optimization sprints and continuous improvement cycles; prioritize corrective actions, estimate effort and impact, and verify KPI improvements post‑implementation.
  • Ensure RF designs and implementations comply with regulatory constraints, RF exposure (EMF) limits, landlord and municipal requirements, and operator standards.
  • Mentor junior RF engineers and field teams on best practices for drive testing, data analysis, RF tool usage, parameter tuning, and proper documentation of changes.
  • Integrate OSS/KPI analytics and data sources (e.g., MME/S1 logs, performance counters, call detail records) to generate root‑cause analyses and to design automated health checks and alerts.
  • Provide pre‑sales and tender support: develop technical proposals, scope of work, resource estimates, and risk assessments for RF network projects and managed services opportunities.
  • Develop and maintain runbooks, standard operating procedures, and configuration baselines for RAN tuning, software upgrades, and fault remediation to accelerate incident response and reduce mean time to repair.
  • Manage vendor acceptance and warranty claims related to RAN equipment and antenna systems by coordinating lab reproduction of issues and negotiating corrective actions with suppliers.
  • Evaluate and recommend test automation and scripting (Python, shell) to streamline data extraction, KPI dashboards, and repetitive analysis tasks to increase team throughput.
  • Support enterprise wireless consultancy projects including private LTE/5G and mission‑critical deployments with emphasis on SLA design, secure network separation, QoS, and lifecycle support.

Secondary Functions

  • Assist sales and account teams with technical clarifications, scope adjustments, and client roadmaps to ensure project proposals align with realistic RF deliverables and timelines.
  • Participate in RFP/RFI responses by providing detailed technical appendices, assumptions, and acceptance test criteria tailored to operator or enterprise needs.
  • Support knowledge transfer and customer training sessions for client NOC and field teams on RF troubleshooting, drive test interpretation, and basic parameter change protocols.
  • Contribute to continuous technical improvement by evaluating new RF tools, plugins, and AI/ML analytics that could enhance anomaly detection and automatic parameter tuning.
  • Maintain up‑to‑date documentation of network changes, lessons learned, and post‑implementation reviews to feed into future design and optimization cycles.
  • Coordinate cross‑functional workshops with core network, transport, security, and applications teams to ensure alignment of RAN changes with end‑to‑end performance goals.
  • Provide on‑call support for escalations during critical events, large‑scale rollouts, or new technology activations to ensure rapid restoration of service and minimal customer impact.
