Staff Engineer, Power Integrity
About The Position
The Staff Engineer, Power Integrity develops electrical systems and circuits for a range of applications. The role researches system concepts, creates plans, and documents designs in schematics and system specifications. It includes testing, simulation, validation, and qualification of systems, making adjustments as needed, and supporting electrical systems through manufacturing. The engineer works with designers, customers, manufacturing engineering, and project leadership to support robust, high-quality product development. Design improvements incorporate feedback from manufacturing, test, supply chain, reliability, industrial design, and simulation reviews. The position leads power-integrity analysis and design across boards and systems, supports end-to-end power delivery, and drives process and quality improvements.
Requirements
- Proven technical understanding of power supply architectures, voltage regulator technologies, power distribution network modeling, and PCB design practices.
- Working knowledge of 2D/3D electromagnetic simulation tools, electromagnetic modeling, and transmission line theory.
- Required experience with associated 2.5D tools such as PowerDC, PowerSI, SIWave, OptimizePI, Sentinel-PI, and nSys; 3D full-wave tools such as HFSS and nWave; and quasi-static tools such as Q3D and nApex.
- Familiarity with LTSPICE, HSPICE, Spectre, AMS, and Simplis models, or equivalent, for system-level transient droop analysis.
- M.S. with at least 7 years of experience, or Ph.D. with at least 5 years of experience.
- Bachelor's degree or an equivalent combination of education and experience, with educational requirements potentially varying by geography.
Nice To Haves
- M.S. and/or Ph.D. academic background in power or signal integrity, power electronics, and analog circuit design.
- Understanding of power supply architectures covering multi-stage and multi-phase voltage regulator technologies, PCB and package design trends and trade-offs, and chip supply design for low- and high-power methodologies.
- Experience developing power-integrity/signal-integrity methodologies, modeling PDNs from system to die, and conducting laboratory correlation and validation.
- Familiarity with Python coding and AI/ML-assisted automation.
- Experience designing and analyzing product power supply solutions.
- Deep understanding of voltage regulator design principles and the electrical performance of system environments.
- Good knowledge of 2D/3D electromagnetic simulation tools, electromagnetics, and transmission line theory.
