About The Position

We are seeking an experienced and analytical Senior Network Performance Engineer with deep expertise in Ericsson RAN software and hardware to lead performance management and optimization across our Radio Access Network. In this role, you will be responsible for driving end-to-end user experience, capacity, and accessibility across Verizon's LTE, VoLTE, 5G-NR (NSA & SA architectures), and Voice over NR (VoNR) deployments. You will utilize Ericsson Management System tools (ENM, MOShell/AMOS), diagnostic traces, and PM counters to deliver top-tier network quality and service reliability.

Requirements

Bachelor's degree or four or more years of work experience
Four or more years of relevant work experience.
Hands-on experience with Ericsson Network Manager (ENM), MOShell/AMOS, and ENM scripting utilities for bulk parameter changes and MO configuration.
Proficiency in 3GPP Rel 15/16/17 architectures, beam management, Massive MIMO, SSB/CSI-RS configuration, EN-DC anchor relations, and 5G-SA/VoNR layer management.
Hands-on experience decoding call traces (GPEH/UETR), diagnostic logs (QXDM, TEMS Investigation, Actix Analyzer, Wireshark), and analyzing VoLTE/VoNR SIP call flows.
Ability to parse large counter datasets and trace logs using SQL, Python, or visualization tools (Tableau, PowerBI).

Nice To Haves

Bachelor’s or Master’s degree in Electrical Engineering, Telecommunications, Computer Science, or a related field.
Five or more years of dedicated hands-on experience in RF engineering and network performance optimization, with a minimum of 3+ years directly working on Ericsson LTE/5G RAN equipment.
Experience with 3rd-party benchmarking analysis (RootMetrics, Ookla, Tutela).
Advanced scripting proficiency (Python, Perl, Shell) for automating MOShell tasks, parameter audits, and KPI reporting.
Experience with Ericsson Open RAN (O-RAN) solutions, RIC, and rApp/xApp performance integrations.

Responsibilities

Lead radio tuning and optimization across Ericsson Baseband and Radio Units (including Massive MIMO, C-Band, and mmWave deployments) for LTE, 5G-NR (NSA & SA), VoLTE, and VoNR services.
Monitor and optimize key Ericsson Performance Management (PM) counters to drive improvements in Accessibility, Retainability, Mobility, and Throughput KPIs.
Parameterize and audit Ericsson feature states and system constants across spectrum layers. Validate features like Carrier Aggregation, Massive MIMO, EN-DC, and Dual Connectivity.
Analyze end-to-end voice quality using Ericsson UE Trace/Cell Trace data and external probes. Troubleshoot SIP signaling, RTP packet loss, jitter, MOS scores, and EPS Fallback (EPSFB) performance.
Monitor and optimize key performance indicators for 5G FWA CPEs on Mid-Band (C-Band) and High-Band (mmWave).
Leverage Ericsson CLI tools (MOShell/AMOS/ENM) to execute health checks, check cell operational states , and run automated parameter audit/turnup scripts.
Identify high-utilization sectors and cell-edge bottlenecks using Ericsson counter data; formulate carrier addition, power control, re-sectoring, or hardware upgrade strategies.
Partner with RF Planning, Operations, and Core teams to resolve complex cross-domain issues.
