  • Debug problems found by our automated test programs and fix the problems.

  • Work on a team implementing, testing, and debugging solutions to help scale EOS software.

  • Work with Customer Support Engineers to analyze problems in customer networks and provide fixes for those problems when needed in the form of new software releases or software patches.

  • 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.

  • Review and contribute to the specifications and implementations written by other team members.

  • Helping to create a schedule for the implementation and debugging tasks, updating that schedule weekly, and reporting it to the project lead
