Description

Year of Exp– 6 to 10 Years

Location- Bangalore

NP- Immediate to 30 days 

Requirements

Requirements

Wireless Domain Expertise:
– Strong understanding of 3GPP specifications (LTE & 5G NR) and O-RAN architecture.
– Deep knowledge of 4G/5G Layer 2 features (MAC, RLC, PDCP) and radio resource management.
– Mastery of End-to-End Call Flows: Initial Access (RACH), Registration, PDU Session Establishment, Handover (X2/Xn), and Release.
– Experience specifically in RAN Capacity and Performance testing. Proven ability to interpret System Design docs and convert them into actionable test scenarios.

Tools & Equipment:
– Hands-on experience with multi-vendor UE Simulators (e.g., TM500) and O-RU Simulators.
– Proficiency with protocol analyzers (e.g., Wireshark) and internal log parsing tools.
– Experience with Linux-based test environments.

Preferred Qualifications
– Experience writing test plans for feature validation, regression, and KPI benchmarking.
– Familiarity with defect tracking tools (JIRA) and CI/CD pipelines.
– Experience with Python or Bash scripting for test automation.
– Familiarity with Virtualized RAN (vRAN) and containerized environments (Kubernetes/Docker).
– Prior experience supporting field trials or carrier acceptance testing.

– Strong technical writing skills for creating Test Strategy, Test Plan, and detailed Performance Analysis reports.
– Experience in a customer-facing role or supporting field trials.
– Excellent communication, presentation and inter-perosnal skills

Key Responsibilities

1. Test Strategy & Planning:
– Review Requirement specifications, Feature Design Documents and translate them into comprehensive Test Strategy and Test Plan documents.
– Define acceptance criteria for functional, performance, capacity and system-level test cases
• 2. Integration & Execution:
– Perform End-to-End (E2E) integration testing, validating the interface between CU, DU, and RU.
– Execute functional testing in close collaboration with the development team to catch issues early in the cycle.
– Conduct rigorous System Testing under load and stress conditions.
– Execute complex load scenarios to validate Cell Capacity (max active UEs) and Data Plane Performance (UDP/TCP throughput).
– Conduct Latency Analysis and Control Plane performance testing

3. Lab & Equipment Management:
– Manage and troubleshoot complex test setups in both conducted and OTA (Over-the-Air) environments.
– Configure and operate industry-standard test equipment, including UE Simulators (e.g., Keysight, Viavi, Spirent) and RU Simulators.

4. Debugging & Triage:
– Perform first-level log analysis (L1/L2 logs) to isolate issues between the UE, RAN, and Core.
– Monitor field defects, lead the triage process, and collaborate with Systems and Dev teams to drive resolutions.
