Wireless Engineer II

Contractual Role on W2

JOB SUMMARY

Responsible to monitor, manage, and optimize the mobile network delivering mobile communications services. Collaborate with internal and external organizations including Wireless Ops, Field Ops, NOC, Net Ops, Engineering, Product management, and 3rd parties to generate the best mobile wireless experience for our customers.

MAJOR DUTIES AND RESPONSIBILITIES

Ensures that the mobile network meets or exceeds Service Level Objectives (SLOs) for RAN, core, backhaul, and devices.

Responsible for optimizing KQIs with the primary goals of maximizing performance, minimizing network transitions, and optimizing throughput and latency.

Drive E2E service performance, triage issues, determine root cause, and resolve impairments in a timely manner.

Analyze coverage, interference, handover, and overall performance quality. Utilize analytics tools to investigate KQIs/KPIs and drill into the network at the appropriate level (national, market, cluster, gNB, vendor type, equipment type, installation type).

Proactively identify opportunities for implementation of automation to identify E2E service performance anomalies and trends.

Responsible for auditing SAS grants, power levels, and channel assignments.

Monitors and audits golden/modifiable configurations daily to ensure alignment to standards. Focuses on most impactful sites/clusters for optimization efforts, which can include:

• Configuration changes (mobility, power, etc.)
• Antenna configuration changes on strand or RoE

Contribute to daily, weekly, monthly cadence of service performance and network problem reports to develop insights into service performance.

Create and implement service improvement plans, confirm successful implementation and operational readiness (knowledge DB, documentation etc.).

Leverage individual or collective service improvement actions/MoPs including prioritization, dependencies, timelines, test plans etc. These plans could involve new releases, upgrades, configuration changes etc.

Validate success of service implementation actions to verify issue resolution with no additional problems being introduced in the network.

Participate in and contribute to the cross-functional knowledge transfer across E2E Performance engineers between the HMNO Core, RAN and SAS domains/technologies to advance skills expertise and foster collaboration.

Create detailed documentation and contribute to the development of processes and procedures that improve E2E service performance and team effectiveness.

Create overall dashboard to convey network health. Utilize analytics reports to create service improvement plans, convey optimization recommendations, and implement approved enhancements.

Performs service impact analyses and validates success of Configuration/Change Management activities.

Adheres to industry specific local, state, and federal regulations, as applicable.

Knows, understands and follows company policy.
