Job Description

Arista delivers networking excellence by designing the industry’s most advanced fabrics for rack-scale and data center-scale AI, alongside the highest-performance and most reliable campus platforms.
We are pushing beyond today’s 1.6T-per-port systems toward higher-bandwidth, higher-radix, and more power-efficient architectures. This work spans high-speed electrical design, cabled backplanes, 200G+ per-lane SerDes, liquid-cooled switching, and next-generation optics that reduce the interconnect power and thermal burden of AI infrastructure.
Our hardware strategy starts with the hardest problems our customers face—scaling bandwidth, controlling power, preserving signal integrity, and delivering uncompromising availability—and carries through first-silicon architecture, system design, validation, manufacturing, and deployment. We work across the full stack of merchant silicon, custom FPGA capability, optics, mechanics, power, thermal design, and EOS-enabled platform integration.
As a Senior Director leading hardware, you will engage directly with hyperscale and enterprise customers to understand their scaling, performance, and deployment challenges—and translate those requirements into differentiated platforms. You will lead and grow our exceptional Sydney engineering organization, set architecture and execution direction, and turn merchant silicon, FPGA innovation, and system-level engineering into industry-leading routing, hyperscale, data center products.

Who You'll Work With 

As an Arista Hardware Engineering Senior Director, you will lead multiple cross-functional teams in the design and verification of an industry-leading portfolio of Networking Ethernet switches.
