Wireless Systems Validation Eng

Job description

Imagine what you can do here. Apple is a place where extraordinary people gather to do their lives best work. Together we create products and experiences people once couldn't have imagined, and now, can't imagine living without. It's the diversity of those people and their ideas that inspires the innovation that runs through everything we do. Minimum Qualifications: Master’s Degree or foreign equivalent in Electrical and Computer Engineering or related field. Experience and/or education must include: Performing Specific Absorption Rate (SAR) measurements for wireless communication devices using standardized RF exposure testing methodologies to evaluate compliance with international regulatory limits under head, body-worn, and extremity operating conditions. Conducting spatial peak SAR evaluations using both 1-gram and 10-gram mass averaging techniques in accordance with internationally recognized RF exposure standards to determine compliance margins for consumer wireless products operating across multiple frequency bands. Preparing and validating tissue-equivalent liquid mixtures by measuring dielectric properties such as conductivity and permittivity to ensure RF absorption characteristics remain within regulatory tolerance ranges during SAR testing. Performing SAR system validation procedures including probe verification, measurement drift assessments, and calibration checks to maintain traceable measurement accuracy and regulatory compliance of RF exposure test systems. Analyzing SAR measurement data to evaluate spatial peak RF energy absorption patterns and determine compliance margins relative to regulatory exposure limits under multiple device configurations and transmission conditions. Applying RF power scaling and extrapolation techniques to evaluate SAR levels under maximum transmitter output power conditions when testing is performed below maximum rated power. Executing automated scanning procedures to map electric field distributions within standardized anthropomorphic phantoms and determining localized RF energy absorption within simulated biological tissue models. Developing automated data processing or workflow optimization tools to improve SAR measurement efficiency, reduce testing cycle time, and ensure consistent analysis of RF exposure compliance results. Develop and validate cellular power tables for mobile communication devices by defining evaluation methodologies, validating compliance under multiple operating conditions, and aligning testing strategies with cross-functional engineering teams to ensure RF exposure requirements are met.
