Role & Responsibilities :

LTE & 5G OAM Development and Automation:

• TRS OAM & OAMSIM Architecture Architected and validated TRS OAM and OAMSIM frameworks for LTE eNodeB and 5G gNB components, ensuring conformance with 3GPP TS 32-series specifications and vendor-specific M-plane interfaces.
• Management Plane Automation Engineered automated workflows for fault, configuration, and performance management using Python, Bash, and CI/CD integrations, enabling zero-touch provisioning and reducing operational overhead.
• Cloud-Native OAM Integration Containerized OAM agents using Docker and Podman, deployed via Helm charts into Kubernetes/OpenShift clusters, supporting dynamic scaling and lifecycle orchestration of network functions.
• Protocol Stack Debugging Performed deep-dive diagnostics on SNMPv2/v3 trap flows, NetConf/YANG schema mismatches, and RESTful API failures, enhancing inter-component telemetry and observability.
• Remote Telemetry & Log Aggregation Implemented remote diagnostics and centralized log harvesting for distributed LTE/5G nodes, leveraging Fluentd and custom collectors to support proactive fault isolation.
• Onboarding Enablement & Compliance Tooling Authored modular onboarding kits, including YAML templates, compliance checklists, and decision trees, enabling reproducible deployment and audit-aligned configuration practices.
• Regression & Scenario-Based Validation Designed and executed regression test suites and scenario-driven validation for OAM feature sets during TRS upgrades, ensuring backward compatibility and system integrity.
• OAMSIM Virtualization Enhancements Extended OAMSIM capabilities to emulate M-plane behavior for early-stage validation of OAM features, decoupling development from hardware dependencies and accelerating test cycles.
• Embedded Risk & Safety Controls Integrated operational risk controls and compliance hooks within OAM workflows, aligning with ISO/IEC 27001 and internal safety governance frameworks.

• Analyzing issues from the UMTS/LTE/5G NR (SA, NSA) protocol stack (NAS/MM/GMM/EMM/ESM/RRC/MAC/RLC/PDCP/L1) or from IMS perspectives (SIP/VOLTE/VOWIFI/VILTE/SMS/VONR/VINR).
• Implementing appropriate fixes based on suggestions from SLSI/MTK, if necessary.
• Collaborating with team members to understand similar issues observed in earlier products and making informed decisions.
• Interacting with other components like RIL/Framework/SIM during root cause analysis.
• Analyzing and root causing critical milestone issues within 24 hours.
• Understanding network signaling (Live/TE) to identify and address issues.
• Verifying chipsets/handset features such as MO/MT speech calls, handover, cell selection/reselection, PS/CS calls, and CSFB functionality.
• Hands-on experience with UMTS/LTE/5G NR (SA, NSA) modem protocol stack development or debugging (NAS/MM/GMM/EMM/ESM/RRC/MAC/RLC/PDCP/L1).
• Experience with IMS-related technologies (SIP/VOLTE/VOWIFI/VILTE/SMS/VONR/VINR).
• Familiarity with Samsung chipsets/tools (Shannon DM) or MediaTek (ELT, etc.) chipsets.
• Log analysis expertise for issues like MO/MT speech calls, cell selection/reselection, PS/CS calls, CSFB functionality, dial-up connections, IMS calls, VoLTE, SCG, MCG, RLF, VoNR, etc., across different models.

Job Role : Physical Layer Developer

Responsibilities :

This role requires meticulous configuration, thorough testing, and continuous optimization of the DU and UESIM components to ensure their effective functioning within the 5G network environment.

Job Role : Physical Layer Developer

Responsibilities:

• Understanding of Carrier Aggregation (CA) Technology : Understand concept of CA, a technology that combines two or more carriers into one data channel to enhance data capacity of a network.
• Implementation of CA in 5G New Radio (NR) : Implement CA in 5G NR to provide multi-connectivity with asymmetric upload and download, providing even more bandwidth to a single user.
• Working with Millimeter Wave Frequencies : Work with millimeter wave frequencies, where up to 700 MHz is available.
• Support for Contiguous and Non-Contiguous Component Carriers (CCs) : Ensure that 5G NR CA supports up to 16 contiguous and non-contiguous CCs.
• Aggregation of New 5G Bands : Aggregate new 5G bands up to approximately 1 GHz of spectrum.
• C/C++ Data Structures and Development : Use C/C++ data structures for implementation of above responsibilities.

This role requires a deep understanding of 5G NR and carrier aggregation technology, as well as ability to implement these technologies in a real-world network environment using C/C++.
