    Arista Networks is looking for world-class Senior/Lead SDN / Networking / Distributed Systems software engineers, with expert knowledge of C/C++ and Python.

    As a Senior/Lead SDN / Networking / Distributed Systems software engineer, you will collaborate and work with customers, product management and engineers to design and build novel Software Defined Networking (SDN) features in EOS that help… networks run effectively and efficiently. These solutions require you to understand SDN technologies such as, but not limited to, EVPN, VXLAN, MPLS, Overlay and Traffic Engineering Controllers, OpenConfig, IETF RFCs, in depth and figure out how to apply it optimally to solve customer problems. You will need to be able to define the SDN features, design data structures and algorithms and tie it all together with the lower layers.

    Arista Software Engineering roles demand a strong and broad software engineering background. While the primary focus area for this role is SDN, the role will not be limited to any single aspect of software development at Arista. It will cover all aspects of software development spanning the addition of new features, debugging problems and fine tuning code for scalability and performance. You will own your projects from definition to deployment and customer interactions, and you will be responsible for the quality of everything you deliver.

    Arista Software Engineering prides itself on a supportive and growth oriented culture. Over time, as your interests change, coupled with evolving business needs you will have the opportunity to switch from SDN to other areas, if you like.
