Integrate with processors and high-speed interfaces, perform simulation, synthesis, place-and-route, timing closure, support lab bring-up and debug, and produce design documentation.

Design and execute test plans and topologies to validate functionality, performance, stability and scalability of Arista networking products. Find hard-to-detect bugs, work closely with developers to complement automated tests, participate in design reviews, and drive platform validation and defect verification.

The Senior Systems Engineer will manage global infrastructure, oversee service availability, perform server maintenance, and design hybrid cloud environments, ensuring operational excellence and security incident response.

Design and execute system-level test cases for a network management system, troubleshoot issues, write bug reports, and improve user experience.

The POC Engineer designs and demonstrates networking solutions for clients, manages complex test topologies, and collaborates on product enhancements.

Provide commercial legal support across Europe: draft, review and negotiate complex commercial and licensing agreements; advise on EU/member-state regulatory matters including GDPR, export controls and anti-corruption; identify legal risk and manage external counsel; partner with business and executives to develop processes and templates to ensure compliance and efficiency.
