Principal Engineer, Power Integrity
About The Position
Marvell is seeking a senior-level Power Integrity Engineer for its Platform Engineering team, supporting board, switch, and optics development for next-generation platform solutions. The role drives execution across complex, cross-functional programs in AI, wired and wireless communications, and critical infrastructure markets. The engineer is responsible for power delivery network (PDN) analysis, power plane design, and verification across board, switch, and optical platforms operating at high-speed data rates. The role partners with circuit design, packaging technology, and board design teams to define and implement power delivery solutions that meet internal specifications and customer requirements. It includes providing technical expertise and design guidance, performing lab-based validation, and working with cross-functional teams and customers to ensure platform designs meet performance, quality, and schedule objectives. The position also provides customer-facing specifications and design-review support, helps develop platform-wide PI methodologies and workflows, and mentors junior engineers. The successful candidate will identify and mitigate power integrity risks across the platform stack and help drive issues to resolution.
Requirements
- Bachelor's degree in Electrical Engineering or a related field and 10–15 years of related professional experience, or a Master's degree and/or PhD in Electrical Engineering or a related field with 5–10 years of experience.
- Strong fundamentals in electromagnetics, transmission lines, and microwave theory, with in-depth knowledge of PDN analysis and high-speed differential and single-ended signals.
- Proficiency in power plane design, modeling, and analysis using tools such as PowerSI, SIwave, or Cadence Sigrity.
- Experience with 2-D and 3-D EM simulation tools such as Ansys HFSS, HSPICE, ADS, or COMSOL.
- Experience with VNA and TDR measurements for board and package characterization, and hands-on experience with lab equipment such as oscilloscopes and logic analyzers.
- Familiarity with decoupling capacitor placement strategies and AC impedance targets across board, switch, and optics platforms.
- Working experience with EM field solvers and time- and frequency-domain tools for power domain analysis on SoC, SerDes, and critical power domains.
- Understanding, debugging, and simulation of EMI/EMC problems related to power delivery.
- Ability to automate PI and packaging activities using scripting tools such as Python.
- Strong analytical, problem-solving, and debugging skills, with a sense of urgency and accountability.
Responsibilities
- Own end-to-end power integrity analysis across SoC package, board, and system-level power domains for board, switch, and optics platforms.
- Develop PDN target impedance specifications and decoupling capacitor strategies, translating power supply requirements into board and package design.
- Perform power plane design, modeling, and analysis, and generate package and PCB models for PI simulation and measurement correlation.
- Analyze VRM and regulator behavior, loop stability and control-loop interaction with the PDN, transient and load-step response, and voltage droop.
- Evaluate power delivery paths for optics integration and ensure power integrity across board-to-module and module-to-switch interfaces.
- Develop PI methodologies, rules, and workflows to meet platform-level specifications across critical power domains.
- Work with packaging, board layout, and switch architecture teams to define PI specifications, review designs, and provide improvement feedback.
- Provide customer-facing PI specifications and ongoing support for customer board design reviews and power delivery analysis.
- Perform VNA- and TDR-based lab measurements to correlate simulation results with real-world power delivery performance.
- Mentor junior engineers and provide technical guidance in power integrity.
- Identify platform-wide power integrity risks, develop mitigation strategies, and escalate issues as needed to drive resolution.
Benefits
- Bonus and equity plans, including a new-hire equity grant and annual equity refreshers.
- Employee stock purchase plan with a 2-year look back.
- Family support programs to help balance work and home life.
- Mental health resources.
- Recognition and service awards.
