Protocol Software- Design /Senior Design Engineer

• ;Contribute to the design and development of MAC and network-layer protocol software for advanced wireless and SDR-based systems.

• ;Participate in translating architectural concepts into reliable and maintainable implementations.

• ;Implement and integrate protocol features, scheduling logic, and inter-process communication mechanisms under Linux environments.

• ;Collaborate closely with PHY and hardware teams to achieve efficient end-to-end data flow.

• ;Own specific protocol modules, from design interpretation to validation and optimization.

• ;Assist in the development, integration, and testing of protocol software components within wireless communication systems.

• ;Work under guidance to implement MAC and network-layer features, focusing on packet handling, link management, and system debugging.

• ;Participate in functional validation, simulation runs, and performance benchmarking of communication stacks.
  Document data flows, timing interactions, and results to support design and testing processes.

• ;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.
