(Sr./Staff) Signal Integrity Engineer

As a Sr. Staff signal integrity engineer, you will be working on challenging SI and PI tasks in globally distributed teams. You will be supporting SI/PI signoff of chip design, package design and PCB design in order to support successful delivery of products of various product lines to market. You will be working with design, test, P&R and application teams globally for modeling of chip high speed I/O and power rails. You will be supporting customers in signing off hardware design or resolving SI/PI issues where system design has constraints. You will also be involved in defining specifications of product electrical performance. You may also be involved in modeling and simulation of EMC issues.

Responsibilities:

Primary (70%):

• Responsible for SI/PI signoff of chip design, package design and PCB design.
• Responsible for modeling high speed I/O and PDN.
• Responsible for customer support for PCB design signoff and issue debug.

Secondary (30%):

• Responsible for product electrical specifications related to high speed I/O.
• Responsible for modeling and simulation of EMC issues.

Requirements:
