Senior Hardware Design Engineer, High Speed Networking

Arista Networks•Nashua, NH

About The Position

Arista Networks is an industry leader in data-driven, client-to-cloud networking for large data center, campus and routing environments. Our Hardware Design Engineering team is at the forefront of developing high-speed networking and Ethernet products used in Enterprise campuses, hyperscale datacenters and bleeding edge AI clusters. The team is responsible for the end-to-end design and development of advanced hardware solutions that meet the demands of modern networking environments. Candidates for this position would be responsible for the entire hardware design process: Authoring functional specifications of high power and high density Ethernet switches used in AI networks, Selecting and qualifying components, Schematic capture and tool-based design verification, Working closely with eCAD teams on PCB layout and component footprints, Working with internal teams to run (or run your own) signal integrity simulations on both power and datapath signals, Working closely with mechanical and thermal engineers on the system general arrangement and physical realization, Specifying PCB stackup and fabrication details with various PCB vendors, Working with internal teams to develop (or develop your own) programmable logic devices for control and timing planes, Working closely with local and overseas Contract Manufacturers (CM), from proto through production, Lab bring up and debug of prototypes, Working closely with diagnostics software engineers on both design validation and manufacturing test development, Driving complex system debug between software, hardware, and test teams, Training CM for high yield test and manufacturing, Guiding groups of engineers and mentoring younger engineers.
