Troubleshoot and resolve complex customer issues involving Arista hardware, software, hyperscaler networks, and AI infrastructure. Investigate network problems, perform root-cause analysis, collaborate with engineering, sales, and account teams, and document technical resolutions. The role supports installation, operation, and maintenance while requiring expertise in networking protocols, Linux, packet analysis, high-speed connectivity, and cloud or AI networking environments.

Develop and maintain Linux kernel features for Arista EOS, integrate upstream kernel releases, and qualify CPU and NIC hardware. Build automated tests, troubleshoot customer and system-test issues, contribute patches to the upstream Linux community, and own projects from definition through deployment. The role also provides technical leadership, cross-functional collaboration, and mentorship to junior engineers.

Develop and deliver software for Arista’s Linux-based EOS network operating system. Responsibilities include designing and implementing C, C++, and Python features; writing specifications, test plans, and automated tests; debugging routing and packet-forwarding issues; supporting customer network troubleshooting; collaborating on larger distributed systems and routing projects; reviewing code; mentoring engineers; and managing project schedules.

Designs, develops, integrates, and maintains low-level CPU firmware, BIOS, and boot-loader software for networking products. Responsibilities include CPU board bring-up, hardware and vendor collaboration, Linux kernel evaluation, automated testing, debugging, open-source contributions, customer issue resolution, technical leadership, and mentoring.

Develop and lead Layer 1 networking software controlling physical-layer components, optics, transceivers, PHYs, and gearboxes. Design, implement, test, debug, and optimize features using C, C++, and Python. Collaborate with customers, product managers, hardware, manufacturing, and test teams to bring new components to market and resolve network issues. Provide technical leadership, own projects through deployment, build telemetry and test infrastructure, and mentor junior engineers.

Develop and optimize PCIe software for networking hardware, including link bring-up, parameter tuning, Linux PCI drivers, virtual memory allocation, error handling, performance measurement, and userspace mediation between ASICs, FPGAs, and PCIe bridges. Build automated validation tests in C, C++, and Python while diagnosing low-level firmware and hardware issues.

Designs and develops network systems software controlling hardware components in switches and routers. Responsibilities include architecting features, coding in C, C++, and Python, building automated tests, debugging customer and system-test issues, collaborating with hardware and manufacturing teams on new products, providing technical leadership, and mentoring engineers. The role requires ownership from feature definition through deployment and customer interaction, with emphasis on hardware control interfaces, scalability, performance, and software quality.

The BIOS Software Engineer will design and maintain low-level CPU firmware, BIOS, and boot loader software, working closely with hardware engineers and contributing to open-source BIOS communities.

Join Arista's SONiC development team as a software engineer to design, implement, and test system software for networking solutions, collaborating with other engineers and customers to resolve issues.

The Software Engineer will develop, test, and maintain the EOS software, collaborate with teams to analyze and fix network problems, and mentor junior engineers.
