• Develop and maintain software for embedded systems, ensuring real-time performance and reliability.
• Conduct thorough network performance analysis and optimization.
• Collaborate with cross-functional teams to ensure seamless integration with network protocols and application stacks.
• Troubleshoot and resolve low-level network and software issues, distinguishing hardware from software challenges.
• Enhance the efficiency, scalability, and stability of networking solutions through innovative development and optimization.
• Develop application-level BSD/POSIX sockets programming solutions for real-time operating systems and hypervisors.
• Work on a variety of other RTOS and tools related technologies.
• Supporting the generation and review of certification data.
• Perform additional job duties as assigned.
