Signal Integrity / Power Integrity Engineer

Job Description

Your Role

As an SI Simulation Engineer, you will be responsible for performing high-speed Signal Integrity (SI) and Power Integrity (PI) simulations and testing across advanced interfaces and platforms. You will work closely with design and layout teams to ensure optimal signal performance and reliability in complex hardware systems.

In this role, you will:

• Perform pre- and post-layout SI/PI analysis for die, package, and board-level designs.
• Conduct simulations using IBIS/IBIS-AMI models and analyze eye diagrams to recommend equalization settings.
• Analyze S-parameters including insertion loss, return loss, crosstalk, and TDR.
• Provide layout constraints and recommendations to ensure signal integrity.
• Select appropriate stack-up materials including dielectric, copper thickness, and impedance control.
• Work with high-speed interfaces such as PCIe Gen3/4/5, DDR4/5, LPDDR4/5, 10G Ethernet, and USB 3.2 Gen1/2.
• Utilize tools like oscilloscopes and VNAs for hardware validation and debugging.
• Identify technical issues and perform root cause analysis for effective resolution.

Your Profile

• Bachelor’s or Master’s degree in Engineering (BE/B.Tech/M.E/M.Tech or equivalent).
• 7–10 years of experience in high-speed SI/PI simulations and testing.
• Strong expertise in interfaces such as PCIe, DDR, LPDDR, Ethernet, and USB.
• Hands-on experience with IBIS/IBIS-AMI models and eye diagram analysis.
• Proficient in S-parameter analysis and signal integrity metrics.
• Knowledge of stack-up design including dielectric selection and impedance control.
• Experience providing layout constraints and collaborating with design teams.
• Good to have: experience with oscilloscopes, VNAs, and hardware debugging tools.
