About The Position

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.

Requirements

• 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 fundamentals PCB stack-up development EMI/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.

Nice To Haves

• 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.
• Experience working with ODMs, EMS providers, and external design partners.
• Understanding of firmware-hardware interactions and platform bring-up activities.
• Exposure to lifecycle management, sustaining engineering, and field failure analysis.

Responsibilities

• 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.
• Design and validate high-speed interfaces including: PCI Express (Gen4/Gen5 and beyond) SAS (12G/24G) SATA NVMe over PCIe Ethernet 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
• 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.
• 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.
• 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.
