Job Title:C Programmer – Telecom Domain

Location– Atlanta, GA

Key Responsibilities

• 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

Qualifications

Required:                   

• Bachelor’s (or higher) in Computer Science, Computer/Electrical/Electronics Engineering, Telecom, or related
• 3+ years of professional experience in C (C99/C11)—especially for performance‑critical or telecom systems
• In-depth understanding of telecom protocols: 3GPP 4G/5G stacks, SIP/H.323, SS7, Diameter, RTP, TCP/IP
• Strong Linux-based development experience, including IPC, POSIX threads, build tools (Make/CMake), version control (Git/Gerrit)
• Solid debugging skills and familiarity with GDB, Valgrind, trace tools
• Good problem-solving ability and communication skills—able to work in distributed teams

Preferred:

• Telecom-specific knowledge: L2/L3 control plane, OAM (e.g. IEEE 802.1ag, Y.1731), RAN/cloud integration
• Experience with embedded systems or real-time OS (Linux kernel, RTOS)
• Exposure to cloud-native technologies (Docker, Kubernetes), automation scripting (Python, Go)
• Familiarity with test tools (Ixia/Spirent), telecom benchmarking standards (RFC 2544), and static analysis/security compliance
• Background in DSP, codecs, hardware interfaces, FPGA/ASIC integration
