Hardware Systems Signal Integrity Engineer - iPhone

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 efforts

The 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!

Description

We are looking for 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":"Lead layout reviews and make data-driven recommendations to achieve robust SI performance on various signals running at low and high speeds.

Perform time-domain and statistical simulations to qualify signal integrity and optimize drive strengths and equalization to ensure adequate voltage and timing margins over high volumes.

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

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

Participate 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.

Work 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.

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

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

Preferred Qualifications

Master or Ph.D. in EE, with 5 years or equivalent of relevant working experience.

A strong background in mobile system engineering is preferred

A passion for engineering with demonstrated initiative, creativity, and innovation.

Excellent communication and presentation skills

Minimum Qualifications

Bachelor's in EE or related field and a minimum of 5 years of industry experience

Strong EE fundamentals and problems solving skills

Strong academic background in EM theory and coupling mechanisms.

Hands-on experience in hardware board-level testing, validation, and with lab equipment (TDR, VNAs, scopes, near field scanning, spectrum analyzers)

Hands-on experience in EM and circuit simulation tools such as Ansys HFSS/Maxwell/SIWave, CST, ADS/Spice/Spectre, Cadence/Sigrity, scripting languages (Python, Perl)

Work experience as Signal Integrity Engineer is a must
