About the company Arista Networks is an industry leader in data-driven, client-to-cloud networking for large data center, campus and routing environments. What sets us apart is our relentless pursuit of innovation. 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. Our solutions are designed to not only meet the current demands of the digital landscape but to also anticipate and adapt to future challenges. At Arista we value the diversity of thought and perspectives that each employee brings to the table. We believe that fostering an inclusive environment, where individuals from various backgrounds and experiences feel welcome, is essential for driving creativity and innovation. Our commitment to excellence has earned us several prestigious awards, such as Best Engineering Team, Best Company for Diversity, Compensation, and Work-Life Balance. 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. About the role 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. Responsibilities We are looking for an experienced, self-motivated, and team-oriented Hardware Engineering Senior Director to drive the creation of industry-leading Cloud Networking Ethernet switches. Arista takes pride in designing and manufacturing the highest-density, highest-bandwidth products on the market. Scale and grow our Sydney hardware organization Manage, mentor, and motivate a team of hardware, firmware, signal integrity, diags, and FPGA engineers with a diverse range of experience levels, from new college grads to experienced industry veterans. Identify, define, and implement new processes and tools that help improve productivity and efficiency within the Hardware team Establish Sydney hardware labs to expand local development and test capabilities, including site requirements, site reviews, equipment and power planning, and site negotiations. Collaborate with SW and Central Engineering Directors to expand local teams outside of Hardware. Provide technical guidance and direction to hardware engineers to resolve complex Hardware bring-up and cross-functional problems Work with product management teams to translate high-level product direction into future system designs with detailed, executable steps for cross-functional teams. Drive Vendor roadmaps of key components (ASICs, connectors, PCB vendors, etc.) to advance Arista’s Hardware designs, as well as align with internal product roadmaps Communicate project status and changes to mitigate unexpected issues. Participate in schematic and board design reviews Develop and communicate priorities across a portfolio of projects. Drive the design of high-quality products with high first-pass yields at manufacturing. Ensure the prototype manufacturing infrastructure and capacity meet product portfolio needs. Act as the initial point of contact for customer escalations, and supervise resolution Engage with customers on product definition and critical escalations as required Requirements BS or MS in Electrical Engineering, Mechanical Engineering, or Physics 4+ years of Management experience, and 10+ years of relevant experience in networking or systems hardware design, particularly in the Enterprise market Proven experience leading hardware engineering teams across multiple simultaneous projects. Prior technical management experience is a must Proficient with high layer count printed circuit boards and high-speed design, with background experience or knowledge of key protocols such as: Ethernet, SMBus, SPI, PCIe, POE, PTP, MDIO Expertise in Designing For Manufacturability (DFM) and collaborating with Contract Manufacturers (CM) Demonstrated success in taking products from concept through to production. Strong communication skills and experience in guiding direct reports, working with other managers or other teams, and interfacing with executive leadership Ability to translate high-level product direction into actionable steps.
