This role demands strong and broad software engineering fundamentals, and ideally a good understanding of networking including capabilities like L2, L3, and fundamentals of commercial switching HW. Your role will not be limited to a single aspect of EOS at Arista, but cover all aspects of EOS.

Responsibilities:

• Write functional specifications and design specifications for features related to forwarding traffic on the internet and cloud data centers.
• Independently implement solutions to small-sized problems in our EOS software, using the C, C++, and python programming languages.
• Write test plan specifications for small-sized features in EOS, 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.
• Worth 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.
• Help to create a schedule for the implementation and debugging tasks, update that schedule weekly, and report it to the project lead.

• BSc, MS or Ph.D. in Computer Science/Electrical Engineering/Computer Engineering with 3+ years of related post graduate work experience
• Knowledge of C, C++, and/or python.
• Knowledge of UNIX or Linux.
• Understanding of L2/L3 networking including at least one of the following areas is desirable:
• IP routing protocols, such as RIP, OSPF, BGP, IS-IS, or PIM.
• Layer 2 features such as 802.1d bridging, the 802.1d Spanning Tree Protocol, the 802.1ax Link Aggregation Control Protocol, the 802.1AB Link Layer Discovery Protocol, or RFC 1812 IP routing.
• Ability to utilize, test, and debug packet forwarding engine and a hardware component’s vendor provided software libraries in your solutions.
• Infrastructure functions related to distributed systems such as messaging, signalling, databases, and command line interface techniques.
• Hands on experience in the design and development of ethernet bridging or routing related software or distributed systems software is desirable.
• 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.
• 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.

This is a mid-level software engineer requirement not applicable for fresh graduates or interns.
