  • 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.
  • Work with the System Test Engineers to analyze problems found in their tests and provide fixes for those problems.
  • Mentor new and junior engineers to bring them up to speed in Arista's software development environment.

Qualifications
  • BS Computer Science/Electrical Engineering/Computer Engineering + 8 years experience, or MS Computer Science/Electrical Engineering/Computer Engineering + 6 years experience, or Ph.D. in Computer Science/Electrical Engineering/Computer Engineering + 3 years experience, or equivalent work experience
  • Expert knowledge of and extensive experience programming in C required. Knowledge of C++ and Python is desirable.
  • Significant hands-on experience troubleshooting issues, fixing bugs and developing features in the Linux kernel.
  • Familiarity with Linux kernel architecture, design and implementation.
  • Familiarity with the upstream Linux community's patching process and procedures.
  • Understanding of IP networking architecture, design and principles
  • Applied understanding of modern software engineering principles and practices
  • Strong problem solving and troubleshooting skills.
  • Strong software design and implementation skills.
  • Ability to work independently and in small teams.
  • Ability to communicate articulately, and document your designs and implementations clearly, and concisely.
  • Familiarity with the x86 and ARM CPU architectures

Compensation Information
