Sr.Engineer, Development

Parallel Wireless; Bengaluru; On-site; INR 2,500,000 - 3,600,000; Full time

Job summary

Parallel Wireless in Bengaluru, Karnataka, is seeking a hands-on RAN software engineer specializing in LTE and 5G NR. The role spans end-to-end RAN stack development, debugging, and cross-layer analysis across 2G/3G/4G/5G technologies.

You will leverage AI/LLMs to improve development productivity, build automation for log analysis, triaging, and root-cause analysis across RATs, while working with Linux-based C/C++ codebases and standard debugging tools.

Qualifications

• Hands-on experience in Cellular RAN software development, preferably in LTE and 5G NR.
• Strong understanding of end-to-end 4G/5G network architecture and 3GPP RAN specifications.
• Extensive development experience across multiple RAN protocol layers (PHY, MAC, RLC, PDCP, RRC).
• Experience with multiple Radio Access Technologies (2G/3G/4G/5G), with deep expertise in LTE and 5G NR.
• Excellent debugging and log analysis skills with end-to-end root cause analysis across cross-layer issues.
• Strong hands-on experience leveraging AI/LLMs for software development, debugging, and productivity.
• Ability to build AI-powered automation frameworks for log analysis and triaging across RATs.
• Strong understanding of networking and telecom interfaces (TCP/IP, UDP, SCTP, Ethernet, F1, E1, Xn/X2, NG, FAPI/SCF).
• Hands-on experience with debugging tools such as GDB, Wireshark, QXDM, TM500, QCAT, protocol analyzers, and custom log analysis utilities.
• Strong C/C++ programming skills with extensive Linux-based software development and debugging experience.
