Role summary

Arista Networks is seeking a Senior Hardware Design Engineer specializing in High-Speed Networking. This role involves end-to-end design and development of advanced hardware solutions for high-speed networking and Ethernet products, focusing on enterprise campuses, hyperscale datacenters, and AI clusters. Responsibilities include authoring specifications, component selection, schematic capture, PCB layout, signal and power integrity analysis, FPGA design, system bring-up, debug, and working with contract manufacturers. The ideal candidate will have 10+ years of relevant experience, a BSEE or MSEE, and expertise in high-speed interfaces, advanced PCB technologies, and mass production DFM. This role requires guiding and mentoring other engineers.

Who You’ll Work With Working closely with cross-functional teams including software, product management, marketing, and manufacturing, our engineers innovate new system architectures and develop high-speed PCBs requiring state-of the-art signal integrity and power integrity design practices.

What You'll Do 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
  • BSEE or MSEE
  • 10+ years of relevant experience in hardware engineering
  • Experience designing networking hardware, particularly involving 100G and 200G PAM4 Ethernet switching
  • Embedded x86/ARM system design is highly desirable
  • Experience designing 20+ layer count boards featuring 50G+ signals, and advanced PCB manufacturing technologies such as sequential lamination, HDI, and ultra-low-loss materials
  • Experience working with multi-phase DC/DC’s for high current, high transient loads
  • Experience working with high speed interfaces, such as DDR, PCIe
  • Writing specifications and drawing schematics for high complexity boards
  • Working closely with CAD designers on complicated layout and routing
  • Working closely with Software and test engineers to bring-up and debug systems
  • Familiarity with signal integrity and power integrity concepts and tools, such as: impedance, PDN’s, differential routing, insertion loss, S-parameters, TDR’s, VNA’s
  • Experience with mass production Design for Manufacturability (DFM)
  • FPGA design and system simulation using Verilog and or VHDL
  • Working with Contract manufacturers
  • Successfully taking products from concept to production

    Iterator over a Binary Search Tree Implement an iterator over a binary search tree. Input: root = [7,3,15,null,null,9,20], calls: next(), hasNext(), next() Output: 3, TRUE, 7 Explanation: The iterator yields the smallest value (3), confirms more nodes exist, then properly yields the next in-order value (7).

  • 5

    Sort a String by Frequency Sort a string by the frequency of its characters. Input: s = "cccaaa" Output: "cccaaa" or "aaaccc" Explanation: Both 'c' and 'a' appear three times, so sorting them by descending frequency keeps them grouped equally.
