Senior Hardware Design Engineer, High Speed Networking, responsible for end-to-end hardware design of high-speed networking products used in Enterprise campuses, hyperscale data centers, and AI clusters.

Work closely with cross-functional teams including software, product management, marketing, and manufacturing to architect and develop high-speed PCBs requiring state-of-the-art signal integrity and power integrity techniques.

Our Hardware Design Engineering team leads the development of high-speed networking and Ethernet products. You will contribute to end-to-end 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
• Collaborating with mechanical and thermal engineers on system 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
• Interfacing with local and overseas contract manufacturers from proto to production
• Lab bring-up and debug of prototypes
• Working with diagnostics software engineers on design validation and manufacturing test development
• Driving complex system debug across software, hardware, and test teams
• Training contract manufacturers for high-yield test and manufacturing
• Guiding groups of engineers and mentoring junior engineers

• BSEE or MSEE
• 10+ years of relevant hardware engineering experience
• 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 (sequential lamination, HDI, ultra-low-loss materials)
• Experience with multi-phase DC/DC converters for high current, high transient loads
• Experience with high speed interfaces (e.g., DDR, PCIe)
• Writing specifications and drawing schematics for high-complexity boards
• Collaboration with CAD designers on layout and routing
• Working with software and test engineers to bring up and debug systems
• Familiarity with signal integrity and power integrity concepts and tools (impedance, PDN, differential routing, insertion loss, S-parameters, TDR, VNA)
• Experience with mass production Design for Manufacturability (DFM)
• FPGA design and system simulation using Verilog and/or VHDL
• Experience working with contract manufacturers
• Proven track record of taking products from concept to production
