We are seeking an experienced Senior Software Engineer with a strong background in telecommunications, 4G/LTE protocol stack development, and real-time systems programming.

The ideal candidate will have hands-on expertise in LTE control-plane and data-plane layers (RRC, MAC, RLC, PDCP) and proven skills in C/C++ development on Unix/Linux environments. This role is focused on core product development, feature implementation, and field issue resolution—not QA, testing, or integration. You’ll work closely with cross-functional teams to design, code, and deliver high-performance LTE solutions.

Key Responsibilities:

Design and develop 4G/LTE protocol stack features (control-plane & data-plane).

Work on protocol layers such as RRC, LTE-MAC, RLC, and PDCP.

Write, optimize, and debug C/C++ code on Unix/Linux/POSIX real-time operating systems.

Analyze and resolve customer-reported and internal QA issues.

Handle field issues, debugging, and customer support escalations.

Bring up and maintain LTE test setups in a running state.

Collaborate with peers to augment LTE/5G knowledge and drive engineering productivity.

Contribute to product performance improvements and ensure high-quality deliverables.

Skills & Experience

Proven experience in telecom software development (LTE / 4G, preferably with exposure to 5G).

Strong expertise in protocol development (RRC, MAC, RLC, PDCP).

Excellent design and coding skills in C/C++.

Hands-on experience with Unix/Linux real-time operating systems.

Strong problem-solving and debugging skills for complex telecom systems.

Experience handling customer issues and fixing field problems.

Excellent communication skills and ability to work across global teams.

Qualifications

Master’s or Bachelor’s degree in Computer Science / Computer Engineering / Telecommunications.

Experience in product development roles (not QA / Integration / pure testing).

Familiarity with telecom standards, LTE architecture, and 5G evolution.

Exposure to telecom product lifecycles and performance optimization.
