Principal Signal & Power Integrity Engineer

Responsibilities

• Development of state‑of‑the‑art packages and printed circuit boards (PCBs) for Max Linear’s next generation products.
• Perform SI/PI simulations and optimization to ensure critical signals meet their required specifications.
• Design and simulate high‑speed signal interfaces and power distribution networks (PDN) for advanced communications SoC packages and PCBs.
• Work on a diverse set of products and applications including RF/mm‑wave modems and transceivers, 5G communication, wireless connectivity, and optical communications (PAM4 1.6T/3.2T DSPs and TIAs) for data‑center connectivity and storage for AI applications.

• Deep understanding of electromagnetic fundamentals, transmission lines, and microwave theory.
• Experience designing and simulating signal and power integrity solutions for high‑speed system components (packages, PCB, connectors).
• Experience with high‑speed channel simulations for Ser Des and transient simulations for SI and PI.
• Understanding of S‑parameters, Smith Chart, and frequency domain analysis.
• Proficiency in 2.5D and 3D simulation tools such as ANSYS HFSS, SIwave, Cadence Sigrity tools, or similar field solvers.
• Expertise in time and frequency domain analysis using tools like ADS, SPECTRE, etc.
• Hands‑on experience with lab measurement equipment like Spectrum Analyzer, Vector Network Analyzer (VNA), Oscilloscopes, TDR.
• Ability to manage package development in collaboration with cross‑functional teams including systems, IC design, IC physical layout, package/PCB layout, and test/characterization teams.
• Self‑motivated with ability to work effectively in both independent and team settings.
• Strong communication, presentation, and documentation skills.
• Excellent problem‑solving skills and ability to excel in a fast‑paced environment.
• BS in Electrical Engineering or related + 9 years of experience, or MS + 7 years of experience, or Ph.D. + 4 years of experience.

• Experience with layout tools such as Cadence Allegro and APD.
• Understanding of different IEEE and Optical standards to define design guidelines.
• Experience with electro‑optic integration on packages; co‑packaging of DC‑DC converters, regulator, TIAs, and optical drivers and multi‑chip package design.
• Familiarity with IC design flows, floor‑planning, IO ring design, on‑chip decoupling, on‑die EM/IR analysis.
• Understanding of different TX/RX circuit designs and how system SI/PI impacts such circuits; use this knowledge to drive the design of packages and PCBs.
• Expertise in equalization techniques such as FIR, CTLE, DFE, FFE and different types of noise in the system and channels and how to optimize EQ settings to mitigate them.
