• Track ongoing developments in the Linux Kernel and identify features and functionality of interest to Arista for our products and for internal development needs.
• Develop and maintain EOS Kernel features and tests using C, C++, and Python, review and contribute to functional and design specifications.
• Build automated tests and test infrastructure to validate the features.
• Work with hardware engineers and vendors to qualify new Kernel dependent hardware components like CPUs and NICs for integration into Arista products.
• Work with the Kernel community to contribute features back to the mainline.
• Work with a team of Kernel engineers to integrate new versions of the Kernel for use in EOS and our internal development.
• Provide technical leadership across features, projects, and tools.
• Work with Customer Support Engineers and customers to analyze, mitigate, and fix problems in customer networks.
