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.
