Job description

Job Description

• Ownership of system Architecture level and design level sign-off on protocol software for high end wireless communication systems
• Algorithmic level decision making backed by a combination of field and theoretical exposure and experience
• Propose, implement and maintain protocol software for industry leading wireless products – including cognitive radios, complex tactical mesh networks, SDR’s, ultra-low latency communication links such as HIL (Human in loop)
• Own the team(s) for one or more communication projects with respect to implementation, qualification and deployment
• Promote a strong ownership culture, ensuring engineers deliver complete solutions within their own domain

Professional Skills

• Strong proficiency in C programming with advanced understanding of memory management, concurrency, and performance optimization.
• Excellent knowledge of Linux internals, including kernel networking stack, device interfaces, and debugging tools (e.g., tcpdump, perf).
• Understanding Layer 2/3 protocols (Ethernet, ARP, VLAN, IP, ICMP, routing protocols such as OSPF/BGP/RIP).
• Expertise in MAC layer design, scheduling, and resource allocation algorithms.
• Experience with IPC mechanisms — shared memory, message queues, semaphores, pipes, UNIX domain sockets
• Hands‑on experience with socket programming (UDP/TCP/RAW).
• Knowledge of routing and forwarding concepts, QoS, and packet scheduling.
• Familiarity with PHY layer concepts and basic understanding of analog/digital waveforms, modulation, and signal timing.
• Proficient in Linux build and debugging tools (gcc, gdb, make, Wireshark, valgrind).
• Fluency, good communication & presentation skills.
• Experience in real‑time or embedded Linux systems is a strong plus.
