Work on a team implementing, testing, and debugging solutions for networking infrastructure include AI networking.
Worth with Customer Support Engineers to analyze problems in customer installations 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.
Help to create a schedule for the implementation and debugging tasks, update that schedule weekly, and report it to the project lead.

Qualifications

BS Computer Science/Electrical Engineering/Computer Engineering + 12 years experience, or MS Computer Science/Electrical Engineering/Computer Engineering + 10 years experience, or Ph.D. in Computer Science/Electrical Engineering/Computer Engineering + 7 years experience or equivalent work experience

Experience programming ASICs and other custom hardware.
Ability to utilize, test, and debug open source software libraries and other software used in your development activities.
Infrastructure functions related to distributed systems such as messaging, signalling, databases, and command line interface techniques.
Applied understanding of software engineering principles.
Strong problem solving and software troubleshooting skills.
Ability to design a solution to a small-sized problem, and implement that solution without outside help. Able to work on a small team solving a medium-sized problem with limited oversight.
