• 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.
