Job Summary

We are seeking experienced Senior Hardware Design Engineers to design and develop high-performance networking hardware for next-generation Ethernet and AI networking systems. The ideal candidate will have 10+ years of experience in complex hardware design, high-speed digital systems, PCB design, signal/power integrity, and taking products from concept through production.

Key Responsibilities

• Design high-power, high-density Ethernet switching hardware for AI and networking applications.
• Author functional specifications and perform component selection and qualification.
• Develop complex flat and hierarchical schematics.
• Work closely with eCAD/CAD teams on PCB layout, routing, and component footprints.
• Define PCB stackups and fabrication requirements with PCB vendors.
• Perform or coordinate signal integrity and power integrity analysis for high-speed datapath and power signals.
• Support prototype bring-up, lab validation, troubleshooting, and system debugging.
• Collaborate closely with hardware, software, test, manufacturing, and systems teams.
• Work with domestic and international Contract Manufacturers from prototype through mass production.
• Drive Design for Manufacturability (DFM), manufacturing yield, and product quality.
• Guide and mentor junior hardware engineers.

Required Qualifications

• BSEE or MSEE or equivalent technical degree.
• 10+ years of relevant hardware engineering experience.
• Strong experience designing networking hardware, particularly 100G/200G PAM4 Ethernet switching.
• Experience designing 20+ layer PCBs with 50G+ high-speed signals.
• Hands-on experience with HDI, sequential lamination, and ultra-low-loss PCB materials.
• Experience with multi-phase DC/DC power designs supporting high-current and high-transient loads.
• Strong experience with high-speed interfaces such as DDR and PCIe.
• Experience with complex schematic capture, component selection, and board-level hardware design.
• Strong understanding of Signal Integrity (SI) and Power Integrity (PI) concepts.
• Experience with impedance, PDNs, differential routing, insertion loss, S-parameters, TDR, and VNA.
• Experience with DFM and mass-production hardware development.
• Experience working with Contract Manufacturers and PCB vendors.
• Strong hands-on experience with hardware bring-up and system-level debugging.
• Proven ability to take products from concept through production.

Preferred Qualifications

• Experience with embedded x86/ARM system design.
• FPGA design and Verilog experience.
• Experience with system-level simulation and validation.
• Experience working on high-performance Ethernet, switching, data center, or AI networking platforms.
• Experience leading technical teams or mentoring engineers.

Ideal Candidate

The ideal candidate is a hands-on senior hardware engineer who can own the complete hardware development lifecycle, from architecture and component selection through schematic design, PCB layout, SI/PI validation, prototype bring-up, debugging, manufacturing, and production.

Must be willing to work 100% onsite in Santa Clara, CA or Roseville, CA.
