Arista Networks is looking for software engineers to  join our IP Routing Protocols development team.  As a core member of the IP Routing Protocols team, you will be part of a dynamic, high caliber team building routing protocol software to run the world's largest data center networks.  Your software will be a key component of Arista's Extensible Operating System (EOS), Arista's unique, Linux-based network operating system that runs on all of Arista's data center networking products.

This role demands a strong and broad software engineering background, and good understanding of IP routing protocols, how they are implemented, and the networks in which they are used. Your role will not be limited to a single aspect of IP routing at Arista, but cover all of our unicast and multicast protocols for both IPv4 and IPv6. At Arista, you will own your projects from definition to deployment, and you will be responsible for the quality of everything you deliver.

The role is open to remote candidates. Employees at or near one of the listed office locations will have the option to (and will be encouraged to) go into the office as needed

  • Write functional specifications and design specifications for small-to-medium sized routing protocol features.

  • Independently implement solutions to small-to-medium scope problems in our routing protocol software, using the C, C++, and python programming languages.

  • Write test plan specifications for small-to-medium sized routing protocol features, and implement automated test programs to execute the cases described in the test plan.

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

  • Work on a team implementing, testing, and debugging solutions to larger routing protocol problems.

  • 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.

  • 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

  • Create and manage a schedule for your overall project tasks, working with your team members to update that schedule weekly, and reporting project status to management.

  • Work with management in making tradeoffs among staffing needs, project scope, and the release date of your project.


  • BS Computer Science + 5 years experience, or MS Computer Science + 3 years experience, or equivalent work experience

  • Knowledge of C or C++

  • Knowledge of UNIX or Linux

  • Understanding of IP networking and IP routing protocols, specifically one of RIP, OSPF, BGP, IS-IS, or PIM.

  • Strong problem solving and software troubleshooting skills.

  • Ability to design a solution to a small-to-medium sized problem, and implement that solution without outside help.  

  • Experience working on a small team solving a large-sized problem with limited oversight.

  • Experience organizing and leading small teams on group software development projects.

Preferred Qualifications:

  • Hands-on experience in the design and development of IP routing protocol or distributed systems software. 

  • Hands-on experience with enterprise or service provider class, ethernet switch/router system software development, or significant PhD level research in the area of network routing and packet forwarding.

If you find yourself checking several but not all these boxes and are interested, we strongly encourage you to apply.
