Test Development, Sr. Engineer

• Design, develop, and validate test hardware, including Test Interface Boards (TIBs), load boards, cables, and connectors for server power supply test systems.

• Create detailed schematics, PCB layout (considering signal/power integrity), generate BOMs, and lead the prototyping and debugging of test boards.

• Select appropriate connectors, cables, and probing solutions to ensure robust interfacing between the Unit Under Test (UUT) and test system instrumentation.

• Collaborate closely with Test Software Engineers and Power Supply Design Engineers to integrate hardware solutions into a fully functional test system.

• Conduct DFT activities to ensure the right test requirements and design inputs for test HW design.

• Perform validation of test hardware, including signal integrity analysis, timing checks, and noise measurements to ensure compliance with test requirements

• Troubleshoot and resolve complex hardware issues related to grounding, noise, crosstalk, and impedance matching within the test system.

• Create and maintain comprehensive documentation for designs, including specifications, validation reports, and standard operating procedures.

• Support manufacturing test teams by resolving hardware-related issues on the production line and implementing continuous improvements to enhance test efficiency, yield, and cost-effectiveness.

• Taking part in the Pre-Development project for new technology evaluation and deployment

• Train technicians and test station operator.
