We leverage the latest advancements in cloud computing, artificial intelligence, and software-defined networking to provide our clients with a competitive edge in an increasingly interconnected world.

At Arista, we take pride in our track record of success and strive to maintain the highest standards of quality and performance in everything we do.

Job Description

Who You’ll Work With

Arista’s Linux Kernel team is responsible for developing and maintaining the Linux kernel in EOS. This includes keeping pace with the latest developments in the upstream Linux Kernel community, and integrating new versions of the upstream kernel as they become available. This work also involves designing and implementing new Linux kernel features, and working with the upstream kernel development community to get these changes incorporated into the mainline Linux kernel code base. Kernel software engineers are also responsible for the CPU subsystems on all Arista products. You will evaluate new CPUs and work with CPU vendors to integrate their kernel support into EOS. You will also help to bring-up and qualify new CPUs in our hardware products.

Arista Software Engineering roles demand a strong and broad software engineering background. While the primary focus area for this role is Linux Kernel software, your work 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.

What You’ll Do

Track ongoing developments in the Linux Kernel and identify features and functionality of interest to Arista for our products and for internal development needs.
Develop and maintain EOS Kernel features and tests using C, C++ and Python, review and contribute to functional and design specifications. Build automated tests and test infrastructure to validate the features.
Work with hardware engineers and vendors to qualify new Kernel dependent hardware components like CPUs and NICs for integration into Arista products.
Work with the Kernel community to contribute features back to the mainline.
Work with a team of Kernel engineers to integrate new versions of the Kernel for use in EOS and our internal development.
Provide technical leadership across features, projects and tools.
Work with Customer Support Engineers and customers to analyze, mitigate and fix problems in customer networks.
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.

Qualifications

BS Computer Science/Electrical Engineering/Computer Engineering + 8 years experience, or MS Computer Science/Electrical Engineering/Computer Engineering + 6 years experience, or Ph.D. in Computer Science/Electrical Engineering/Computer Engineering + 3 years experience or equivalent work experience
Expert knowledge of and extensive experience programming in C required. Knowledge of C++ and Python desirable.
Significant hands-on experience troubleshooting issues, fixing bugs and developing features in the Linux kernel.
Familiarity with Linux kernel architecture, design and implementation.
Familiarity with the upstream Linux community’s patching process and procedures.
Understanding of IP networking architecture, design and principles
Applied understanding of modern software engineering principles and practices
Strong problem solving and troubleshooting skills.
Strong software design and implementation skills.
Ability to work independently and in small teams.
Ability to communicate articulately, and document your designs and implementations clearly, and concisely.
Familiarity with the x86 and ARM CPU architectures
