About The Position

As a Power Integrity Engineer for Data Center and Mac platforms, you will lead
the design, simulation, and validation of power delivery networks (PDNs) for
next-generation server and The Power Integrity Engineer will be responsible for
pathfinding studies during silicon development, providing feedback to silicon
and packaging teams on system integration trade-offs. This includes performing
target impedance analysis, transient voltage droop, and phase margin/stability
analysis. The candidate will work closely with System Design teams to provide
detailed layout strategies and guidelines during design execution and
collaborate with HW Validation teams to develop test suites for system-level
validation, evaluating design margins on power domains. The role provides PI
support throughout the project design process, from system pathfinding and
verification to characterization reviews, with continuing guidance through
production and ramp.

Requirements

• Proven technical understanding of power supply architectures, voltage regulator technologies, power distribution network (PDN) modeling and PCB design practices
• Working knowledge in 3D/2D EM simulation tools, electromagnetic modeling, and transmission line theory
• Skills with associated tools for 2.5D (PowerSI, SIWave, Sentinel-PI, nSys), 3D Full wave (HFSS, nWave), quasi-static tools (Q3D, nApex) is required
• Relevant proven understanding of HSPICE, Spectre, AMS, and Simplis models for system-level transient droop analysis
• M.S. with minimum 3 years of experience, or PhD (preferred) with a minimum of 3 years of experience

Nice To Haves

• Experience with CPM (Chip-Power-Model) usage for system transient analysis
• Understanding of die-package-board power delivery network co-design constraints and tradeoffs
• PCB and PKG layout skill
• Experience with Perl, Python, or other scripting languages
• MATLAB experience
• Excellent documentation and communication skills
• Proven ability to work independently, mentor others and innovate
• Demonstrated experience in driving initiatives that improved process, procedures and result quality
