About the role

JD – Solution Architect, OAM (2G/4G/5G)Role overview

Position: Solution Architect, Unified OAM for 2G, 4G and 5G RAN
Location: Gurgaon
Experience: 12+ years in 4G/5G OAM product development, plus years leading delivery of OAM programs
The role: own the OAM architecture and design from discovery to design sign-off, then guide the team through implementation and release

Key responsibilitiesArchitecture and design

Own the OAM architecture: a RAT-independent core (boot orchestrator, configuration, fault, performance, process health, software and log, inventory managers) with RAT adapters kept separate
Define one configuration tree and one alarm and counter framework across 2G, 4G and 5G, with conflict checks on shared resources
Design the northbound layer (SNMP agent and MIB, XML or NETCONF server, syslog client) and the O1 interface to an SMO
Design the RU M-plane manager (NETCONF client, YANG models) for 4T4R and 32T32R massive MIMO RUs, including array, beamforming and calibration objects
Design the fronthaul and sync manager: clock priority (local GNSS, external PTP, SyncE), hardware holdover and cell gating signalled to L1
Define the HAL so the same OAM runs on the platforms like Qualcomm and Intel
Design process health supervision and recovery levels

Discovery and delivery

Lead onsite discovery: study the existing OAM and platform, confirm assumptions and scope additions, and take the design to customer sign-off
Map 3GPP and O-RAN requirements (CM, FM, PM, trace) to design components and the test plan
Break the design into work for core OAM, RAT, M-plane, northbound and base platform teams
Review design, code and test results; mentor senior leads and developers
Work with the test lead on a framework with traceable test cases, simulators and automated regression
Drive debugging and root-cause analysis on integration, performance and field issues

Stakeholders
