Responsibilities

• Lead hardware circuit design, schematic development, and PCB layout review for high-performance datacenter switches (Top-of-Rack, Leaf, and Spine architectures) to ensure robust system performance and manufacturability.
• Evaluate and integrate advanced networking silicon (e.g., Broadcom, Marvell), high-speed interconnects, and Baseboard Management Controllers (BMC).
• Drive design verification, system bring-up, high-speed signal integrity validation, debugging, and root cause analysis, including RMA failure resolution.
• Collaborate closely with mechanical and thermal teams to address high power density and cooling challenges inherent in 1U/2U rackmount data center environments.
• Own BOM management and support production to ensure smooth transition from NPI to mass production for complex, high-layer-count PCBAs.
• Participate across the full product lifecycle from NPI, MP to EOL.
• Collaborate with cross-functional teams including layout, component engineering, firmware, mechanical, power, thermal, QA, software, PM, ID, and compliance.

Qualifications * Bachelor's degree or above in Electrical Engineering or a related field. * 5+ years of hands-on experience in system-level hardware design, specifically for datacenter switches, enterprise core routers, or high-density server/storage networks. * Deep understanding of high-speed Ethernet technologies, including 100G/400G/800G interfaces (QSFP28, QSFP-DD, OSFP), MAC/PHY protocols, and advanced switching fundamentals. * Experience with high-speed board design, signal integrity analysis (PAM4, PCIe Gen 5/6, high-speed SerDes), and impedance control. * Experience in hardware validation, debugging, and failure analysis in production environments. * Familiarity with datacenter hardware requirements, including hot-swappable redundant power supplies (CRPS), field-replaceable fan modules, and compliance standards (ESD, EMI/EMC, safety). * Proficiency in hardware design tools such as OrCAD Capture, Cadence Allegro, or Mentor PADS.

Nice to Have

• Experience with Baseboard Management Controller (BMC) hardware design (e.g., ASPEED AST2500/2600) and related firmware integration.
• Familiarity with Open Compute Project (OCP) networking standards, rack-level power architectures (e.g., 48V DC-DC conversion), or liquid cooling solutions.
• Experience leading cross-functional teams in complex, high-power hardware system development.
