Network Stack Developer

Key Responsibilities:

• Develop, Validate and maintain high speed L2/L3 protocol stacks over NIC drivers in Linux kernel / User mode and other Host/Device operating systems.
• Implement and optimize L2/L3 protocols, RDMA, and RoCE for high-performance networking applications.
• Collaborate with cross-functional teams to develop, test NIC firmware and protocol stack software, Troubleshoot and resolve NIC-related technical issues.
• Develop and maintain test frameworks for NIC performance and functionality testing.

Required Skills:

• Proficiency in C, C++, and Python programming languages.
• In-depth knowledge of networking protocols, including TCP/IP, IPv4, and IPv6 and their packet formats.
• Hands-on experience with tools for capturing and analyzing protocol packet exchanges across high-speed interfaces.
• Understanding of high-performance multi-core CPU/GPU clusters and their high-speed interconnect fabric interfaces such as PCIe and Infiniband.
• Working familiarity with Host Channel Adapters (HCAs) or bridges that parse, translate and route data from standard NW stacks into fabric-specific transport logic would be an added advantage.

Desirable Skills:

• Hands-on experience developing AI training/Inference application would be valuable.
• Python scripting for test log analysis and NIC behavior triage.
• Experience with machine learning and deep learning frameworks and their underlying NW payload transfer.
• Working experience with latest AI coding copilot-based flows to generate, review, test and release code.

Education:

• Bachelor's or Master's degree in Computer Science, Electrical Engineering, or a related field with a focus on computer systems or networking.

Experience:

• At least 6+ years of experience in L2/L3 stack development, using modern NIC device driver APIs including kernel mode and user mode drivers.
• Experience working with high-speed cloud data center server stack development
