Senior 5G Network level Engineer

Team: IT

Accountabilities:

• Execute end-to-end validation of 5G RAN and Small Cell systems against 3GPP Release 15/16/17 specifications.
• Analyze protocol signaling (RRC, NGAP, XnAP, NAS) to identify deviations and ensure standards compliance.
• Perform deep root cause analysis of complex network issues using tools such as Wireshark, QXDM, and QCAT.
• Debug call processing flows including ENDC (NSA), SA architectures, mobility events, and handover failures.
• Investigate performance issues such as throughput drops, signaling failures, and security tunnel setup problems.
• Develop Python and Robot Framework scripts to automate protocol testing and data analysis workflows.
• Leverage AI tools to analyze logs, process PCAP files, and accelerate failure diagnostics.
• Manage lab environments, including network element configuration, SeGW setup, and core network simulation tuning.

Requirements:

• 5–10 years of experience in 5G RAN, Small Cells, or telecom protocol engineering roles.
• Strong understanding of 3GPP standards including TS 38.331, TS 38.413, TS 38.423, and TS 24.501.
• Hands-on expertise in LTE/5G call flows, mobility events, handovers, and RAN feature debugging.
• Solid knowledge of IETF protocols such as IPsec, IKEv2, SCTP, and secure network gateway integration.
• Experience with protocol analysis tools such as Wireshark, QXDM, QCAT, XCAL, or XCAP.
• Proficiency in Python and scripting for automation, log analysis, and packet processing.
• Familiarity with AI-assisted debugging tools and data-driven engineering workflows.
• Strong analytical mindset with excellent problem-solving and troubleshooting skills.
• Ability to work independently in complex lab and multi-vendor environments.

Benefits:

• Competitive salary aligned with experience and expertise.
• Opportunity to work on advanced 5G and next-generation telecom technologies.
• Exposure to cutting-edge RAN systems, protocol stacks, and global standards.
• High-impact engineering role with ownership of complex validation environments.
• Work with advanced automation and AI-driven engineering tools.
• Professional growth in a highly specialized and evolving telecom domain.
