• Develop, debug, and optimize C-based telecom components: L1/L2/L3 stacks, signaling, media handling, billing, or messaging systems
• Implement and enhance network protocols (TCP/IP, SIP, RTP, Diameter, NGAP/S1AP—3GPP)
• Write modular, reusable, and efficient C code; manage memory manually to avoid leaks and buffer issues.
• Use debugging tools (GDB, Valgrind), static analysers (Coverity, Cppcheck), and trace signal flows to root cause complex issues.
• Collaborate in Agile/scrum environments—plan, code & test features, participate in design/code reviews, and deliver high-quality software on time.
• Produce technical documentation: software design specs, interface definitions, test plans
• Work cross‑functionally with hardware, firmware, testing, QA, and system engineering teams
