Principal Signal & Power Integrity Engineer
Location: On-Site, Carlsbad, CA

Job Description:

At MaxLinear, we believe in pushing the boundaries of communications technology to create smarter, more connected solutions. We’re on a mission to revolutionize how the world communicates, and we need a Principal Signal & Power Integrity Engineer to help lead the charge. In this exciting role, you’ll be at the forefront of developing state-of-the-art packages and PCBs for next-gen products that power 5G communications, RF/millimeter-wave modems, and optical communications for AI-driven data center connectivity.

If you're a hands-on engineer who thrives on solving complex signal integrity (SI) and power integrity (PI) challenges, then this is the opportunity you've been waiting for. Bring your expertise in high-speed designs, simulation tools, and system-level problem solving to MaxLinear, and help shape the future of data connectivity and wireless communication.


What You’ll Be Doing

As a Principal SI/PI Engineer, you'll be responsible for:

  • Designing High-Speed Signal Interfaces: Developing and simulating signal and power integrity solutions for SoC packages, PCBs, and high-speed interconnects used in advanced communication systems.

  • Leading Package Development: Collaborate across functional teams (systems, IC design, PCB/IC layout, test, and characterization) to develop and optimize package designs for high-performance components.

  • Performing SI/PI Simulations: Utilize cutting-edge tools to perform signal and power integrity simulations, optimizing high-speed channels for SerDes, and conducting transient simulations for both SI and PI.

  • Simulating Power Distribution Networks (PDN): Design power distribution networks and ensure power integrity through careful analysis of S-parameters, Smith charts, and frequency domain analysis.

  • Collaborating with Cross-Functional Teams: Work closely with teams from systems engineering to IC layout and test to ensure all design specifications are met and high-quality standards are maintained.

  • Driving Innovation: Push the boundaries of what’s possible in RF/microwave design, working on next-gen products like PAM4 800G/1.6Tbps DSPs, TIAs, and 5G transceivers.


What We’re Looking For

We’re looking for a candidate with:

  • Deep Expertise in Electromagnetics: Strong understanding of microwave theory, transmission lines, and signal propagation.

  • Hands-On Experience with SI/PI Design and Simulations: At least 7-9 years of experience designing high-speed components, including experience with ANSYS HFSS, SIwave, Cadence Sigrity, or similar field solvers.

  • Simulation Mastery: Proficiency in time-domain and frequency-domain analysis, with tools like ADS, SPECTRE, and S-parameters.

  • Lab Measurement Expertise: Experience using lab tools such as Spectrum Analyzers, VNAs, Oscilloscopes, and TDR to validate designs.

  • Collaboration and Leadership: Ability to manage complex development projects and work across teams to bring high-performance solutions to life.

  • Educational Background: A BS in Electrical Engineering or related field with at least 7 years of relevant experience, or MS + 5 years or PhD + 4 years of experience.


Preferred Qualifications

While not required, the following are considered a plus:

  • Experience with Layout Tools: Familiarity with Cadence Allegro, APD, and other PCB layout tools.

  • Electro-Optic Integration: Experience with co-packaging of DC-DC converters, regulators, TIAs, and optical drivers.

  • Multi-Chip Package Design: Knowledge of IC design flows, floor planning, IO ring design, and on-chip decoupling.

  • Industry Standards: Understanding of IEEE and Optical standards to define design guidelines.
