**Project description:**
We are seeking a talented and experienced Software Engineer with expertise in developing IP communication protocols and strong proficiency in C++. As a key member of our software engineering team, you will play a crucial role in designing, implementing, and maintaining robust and efficient communication protocols for our software products.

Design and develop IP communication protocols: Design, architect, and implement scalable and reliable IP communication protocols to enable efficient data transfer and communication between networked devices.
Collaborate on protocol specifications: Work closely with cross-functional teams, including network architects, system engineers, and product managers, to define and refine protocol specifications based on project requirements and industry standards.
Implement protocol features: Write clean, efficient, and well-documented code in C++ to implement protocol features, including packet handling, message parsing, error detection and correction, congestion control, and security mechanisms.
Conduct protocol testing and optimization: Conduct rigorous testing and debugging of protocols to ensure functionality, performance, and interoperability. Optimize protocols for efficiency, latency, and throughput, and address any identified bottlenecks or issues.
Collaborate with the development team: Collaborate with other software engineers, QA engineers, and system architects to integrate protocols with other software components and ensure seamless interoperability across the system.
Documentation and technical support: Create comprehensive technical documentation, including protocol specifications, design documents, and API references. Provide technical support to internal teams, customers, and partners regarding protocol-related inquiries, troubleshooting, and integration.
