  • Work with upstream open source BIOS communities to contribute features back to the mainline.
  • Review and contribute to functional and design specifications written by other engineers.
  • 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.
  • Provide technical leadership across features, projects and tools.
  • 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 + 3 years experience, or MS Computer Science/Electrical Engineering/Computer Engineering + 2 years experience, or Ph.D. in Computer Science/Electrical Engineering/Computer Engineering + 1 years experience, or equivalent work experience
  • Expert knowledge of and extensive experience programming in C required. Knowledge of C++ and Python is desirable.
  • Experience designing and developing software in CPU firmware, BIOS and boot loader environments.
  • Experience bringing up new CPU boards.
  • Significant hands-on experience diagnosing problems, troubleshooting issues, and fixing bugs in low-level CPU firmware, BIOS and boot loader software.
  • Familiarity with Linux kernel architecture, design and implementation desirable
  • Understanding of IP networking architecture, design and principles desirable
  • 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 and experience working with the x86 and ARM CPU architectures
