The people here at Apple don't just create products - they create the kind of wonder that's revolutionized entire industries. It's the diversity of those people and their ideas that inspires the innovation that runs through everything we do, from amazing technology to industry-leading environmental effortsThe iPhone System Technologies organization is seeking a Signal Integrity Engineer for the hardware development team. In this highly collaborative role, you will interface with various technology and module teams (such as camera, display, sensors, etc.) to influence their integration at the system level with emphasis on design and debug of high-speed and low-speed links.

Our team is collaborative, creative and passionate about what we do and the products we make. We want to hear from you!

DescriptionWe are seeking a candidate with a strong background in Signal Integrity including Lab and Simulation experience. Knowledge of electromagnetics, transmission line theory, extracting channel models and simulating EMI/Crosstalk are expected. Channel elements include rigid PCBs, flexible printed circuit boards, connectors, and other components in a mobile system.

Responsibilities:

Participating in schematic reviews to inform selection and placement of various system level channel components including RLC filters, DC-blocking capacitors, board to board connectors, etc.

Simulating loss, crosstalk, and coupling concerns to guide layout & system design using 3D/2.5D/2D EM modeling tools.

Leading layout reviews and making data-driven recommendations to achieve robust SI performance on various signals running at low and high speeds.

Performing design feasibility study, design testing and verification, and system bring up.

Providing design guideline and supporting to system architecture design, board layout, product bring up, debug, validation, and factory builds.

Performing time-domain and statistical simulations to qualify signal integrity and optimizing driving strengths and equalization to ensure adequate voltage and timing margins over high volumes.

Performing lab measurements such as VNA characterization, Eye Diagrams, BERTs and Compliance Testing.

Working with multi-functional teams to define design requirements for improved EM performance and system coexistence by developing and improving design methodologies to achieve minimal EMI.Preferred QualificationsPh.D. in EE with 5 years or equivalent of relevant working experienceA strong background in mobile system engineering is preferredA passion for engineering with demonstrated initiative, creativity, and innovation.
