SUMMARY

Take the major responsibility for power design for Server & Storage, Networking Switch and Telecom products. Drive innovation and continuous improvement within Jabil E&I Design team by utilizing new design technologies and methodologies.

Provide exceptional support to internal and external customers, team members, and other persons through technical project cooperation.

ESSENTIAL DUTIES AND RESPONSIBILITIES include, but are not limited to the following :

Work as a power lead for the power design on the projects from kick off to mass production. Work with customer, system architect, and internal engineering team to define the whole system power delivery architecture.

If it is a customer project, need to face the power counterpart in customer side and drive the weekly technical discussion with customer to track the power design status, issues, etc.

Work with Electrical Engineer to provide the power block diagram based on the power budget. Select the suitable topologies according to the power block diagram, including CPU core power regulators, DC-DC POL, hot-swap control, Li-ion battery charger and discharger, Oring control circuit, Current sharing control circuit, EMI filtering circuit, Super-cap control circuit, etc.

Work with the suppliers to select the suitable components including controller, converter, MOSFET, Inductor, Capacitor, Fuse, Transistor, Connectors, Cables considering performance, efficiency, dimension, Use the CAD Tools like ORCAD Capture or Mentor to work out the power schematic Do the power related calculations and simulations to ensure the stability and reliability of the power design Work out the power layout guideline and work with the Layout Engineers for the placement and layout review.

Bring up the board together with the Electrical Engineer and Firmware Engineer. Work out the DC / DC test plan according to the generic power test plan and customer’s special requirements.

EVT : full test; DVT : regression test) Do the DC / DC verification based on the items in the test plan and work out the test report.

Work on the trouble shooting, issue analysis, and finding solutions for the defects. Implement the design changes on the DVT schematic and board file.

Review the recommended second source from the Component Engineer and come out the corresponding second source test plan & report.

Support power related failure analysis on the RMA board Provide technical support to manufacturing team for the power related issues during development phase, and after mass production.

For certain project, need to work with the BBU vendor to manage a customized BBU development, including technical review, schedule control, and cost control, etc.

Mentor the Senior or Junior power engineers for hard skills and soft skills. Review the Senior or Junior power engineer’s deliverables.

Keep learning the latest technology and techniques to make sure the power design up-to-date, robust, better performance and cost effective.

Person Background :

Candidates should have at least 7 years DC / DC power design experience. Typically, the following essential qualifications and experiences would be requested :
