Position Summary: We are seeking a highly skilled Senior ECAD PCB Design Engineer to lead the design and development of complex printed circuit board assemblies (PCBAs) supporting next-generation server and storage platforms, including high-density systems such as 2U24 Servers and 2U20 JBOD (Just a Bunch of Disks) architectures. This role requires deep expertise in Mentor Graphics tools, high-speed digital design, PCB architecture, signal integrity, power distribution, and system-level integration. The successful candidate will work closely with electrical, mechanical, thermal, firmware, manufacturing, and validation teams to deliver reliable, high-performance products that meet demanding performance, reliability, and compliance requirements. The engineer will serve as a technical leader throughout the product lifecycle—from concept and architecture through schematic development, PCB implementation, validation, compliance testing, and production release.

Key Responsibilities: PCB Architecture & Design client General Information Lead schematic capture, PCB architecture definition, component selection, and board-level design activities for server and storage products. Design complex multilayer PCBAs supporting high-performance compute, storage, networking, and management functions. Develop robust power distribution networks (PDN) and power sequencing solutions. Ensure designs meet electrical, thermal, manufacturability, reliability, and cost objectives. High-Speed Signal Design Design and validate high-speed interfaces including: PCI Express (Gen 4/Gen 5 and beyond)SAS (12G/24G)SATANVMe over PCIeEthernet interfaces (10G/25G/40G/100G/400G)DDR4 and DDR5 memory interfaces High-speed backplane and SERDES-based interconnects Perform design reviews focused on: Controlled impedance implementation Differential pair routing Length matching Return path continuity Crosstalk mitigation Via optimization and stub reduction Power integrity and noise management Chassis-Level Integration Collaborate with chassis, mechanical, and thermal teams to ensure successful integration within dense server and storage enclosures. Evaluate board placement, connector strategies, airflow constraints, serviceability requirements, and manufacturability. Support architecture decisions that balance performance, reliability, cost, and mechanical constraints. Design Reviews & Technical Leadership: Lead cross-functional engineering reviews. Develop and maintain PCB design guidelines, best practices, and reusable design methodologies. Mentor junior engineers and provide technical oversight to outsourced layout resources when applicable. Review external design deliverables to ensure adherence to product and company standards. Client General Information Manufacturing Support Partner with manufacturing, supplier quality, and NPI teams to support prototype builds and production ramp activities. Investigate and resolve manufacturing, assembly, and field reliability issues. Support DFM, DFA, and DFT initiatives.

Required Qualifications: Bachelor's degree in Electrical Engineering, Computer Engineering, or related discipline.5–10+ years of experience in complex PCB and PCBA design. Proven experience designing boards for: Enterprise servers Storage systems Networking equipment High-performance embedded platforms Strong expertise in: High-speed digital design Signal integrity fundamentals Power integrity fundamentalsPCB stack-up developmentEMI/EMC mitigation Experience with modern ECAD design platforms such as: Siemens Xpedition Cadence Allegro Altium Designer Equivalent enterprise-level ECAD tools Knowledge of DDR4/DDR5, PCIe, SAS, SATA, SERDES, and Ethernet technologies. Experience interpreting vendor reference designs, compliance requirements, and chipset design guides. Strong understanding of PCB fabrication and assembly processes.

Preferred Qualifications: Experience with 2U server, JBOD, JBOF, or storage enclosure architectures. Familiarity with BMC, management controllers, and platform management interfaces. Experience supporting SI/PI simulations using industry-standard tools. Knowledge of thermal design considerations for high-density systems. Client General Information Experience working with ODMs, EMS providers, and external design partners. Understanding of firmware-hardware interactions and platform bring-up activities.
