Job Description

Position Overview

We are seeking a Senior ECAD PCB Design Engineer to lead the design and development of complex PCBAs for next-generation enterprise server and storage platforms, including 2U24 Servers and 2U20 JBOD architectures . The ideal candidate will have extensive experience in high-speed digital PCB design, Mentor Graphics tools, signal integrity, power distribution, and system-level integration while collaborating with cross-functional engineering teams throughout the product lifecycle.

Key Responsibilities

PCB Design & Architecture

  • Lead schematic capture, PCB architecture, component selection, and board-level design.
  • Design complex multilayer PCBAs for enterprise servers, storage systems, and networking platforms.
  • Develop power distribution networks (PDN) and power sequencing solutions.
  • Ensure designs meet electrical, thermal, manufacturability, reliability, and cost objectives.

High-Speed Digital Design

  • Design and validate high-speed interfaces including:
  • PCIe Gen4/Gen5
  • SAS (12G/24G)
  • SATA
  • NVMe
  • Ethernet (10G–400G)
  • DDR4/DDR5
  • SERDES-based interconnects
  • Perform design reviews focusing on:
  • Controlled impedance
  • Differential pair routing
  • Length matching
  • Crosstalk mitigation
  • Power integrity
  • EMI/EMC considerations
  • Via optimization and return path continuity

System Integration

  • Collaborate with Electrical, Mechanical, Thermal, Firmware, Manufacturing, and Validation teams.
  • Support board placement, connector selection, airflow optimization, and chassis integration.
  • Balance performance, reliability, manufacturability, and cost constraints.

Technical Leadership

  • Lead engineering design reviews and technical discussions.
  • Develop PCB design standards, methodologies, and best practices.
  • Mentor junior engineers and review outsourced PCB layouts.
  • Ensure compliance with engineering and quality standards.

Manufacturing & Product Support

  • Support prototype builds, NPI activities, and production ramp.
  • Troubleshoot manufacturing, assembly, and field reliability issues.
  • Drive Design for Manufacturability (DFM), Design for Assembly (DFA), and Design for Test (DFT) initiatives.

Required Qualifications
