System Signal Integrity Engineer
System Signal Integrity Engineer Austin,Texas,United States Hardware 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. **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. Some of the key job responsibilities are: 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. 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. 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. **Minimum Qualifications** + 2+years of experience + Bachelor’s in EE or related field + Must have strong EE fundamentals and problems solving skills + Must have strong academic background in EM theory and coupling mechanisms. + Must have experience in signal integrity + 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) **Key Qualifications** **Preferred Qualifications** + Masters or PhD in EE or related field + Experience in 3D EM simulations for debugging and mitigating complex EM coexistence issues + System or module level experience in consumer electronics hardware design + Familiarity with firmware to independently lead hardware bring up and debug efforts + Practical experience with TX/ RX equalization circuitry and understanding how they impact channel performance + Experience with standard high-speed interfaces such as Display Port, USB, MIPI, PCIe etc. + Experience with standard low-speed interfaces such as I2C, SPI, SPMI, I2S, etc. + Ability to effectively communicate complex topics and ideas with cross-functional teams who may not share the same background **Education & Experience** **Additional Requirements** + Apple is an equal opportunity employer that is committed to inclusion and diversity.
