Wireless Systems Validation Eng

Apple • Cupertino, CA

7h • $163,031 - $225,300 • Onsite

About The Position

Apple Inc. is hiring a Wireless Systems Validation Eng in Cupertino, California, and various unanticipated locations throughout the USA. The role involves developing wireless systems with a focus on multi-radio coexistence design. The engineer defines coexistence performance requirements and test methodologies, works with cross-functional teams and external partners, provides design guidelines, reviews PCB and flex layouts, and debugs multi-radio coexistence issues.

The position supports manufacturing tests, debugs failed units, conducts large-sample failure analysis, and develops system mitigations to optimize product performance. It also analyzes root causes of parametric test failures and suboptimal results, identifies causes of test failures efficiently, anticipates performance issues from test results, and provides integration recommendations to improve overall radio-system performance and quality. The engineer uses spectrum analyzers, base station emulators, network analyzers, and other RF test equipment to measure and analyze radio-frequency signals in mobile devices. International travel is required for 15% of the role. The schedule is 40 hours per week.

The stated base-pay range is $163,031–$225,300 per year. Apple also describes potential employee stock programs, comprehensive medical and dental coverage, retirement benefits, discounted products and free services, and reimbursement for certain career-related educational expenses, including tuition. The role might also be eligible for discretionary bonuses or commission payments and relocation.

Requirements

• Master's degree or foreign equivalent in Electrical and Computer Engineering or a related field.
• Experience and/or education in full-cycle physical design and layout of sub-micron RFICs to identify potential interactions among RF components and drive system-level design improvements.
• Experience and/or education performing failure analysis to identify and resolve complex system-level hardware issues during development.
• Experience and/or education conducting hands-on rework, including soldering, tuning, and reassembly, to evaluate mockups and close performance gaps.
• Experience and/or education in microwave signal-chain architecture, link-budget analysis, and electromagnetic simulation of phased-array antennas.
• Strong fundamental understanding of RFIC and RF system design principles.
• Experience and/or education communicating circuit-design and signal-integrity design, validating analog/mixed-signal blocks such as ADC/DAC, and characterizing EVM and quantization noise.
• Experience and/or education configuring RF test equipment, including callboxes, signal generators, and signal analyzers, to conduct measurements and debug hardware issues.
• Experience and/or education collaborating with vendors to improve RF grounding, mitigate EMI, and drive mass-production solutions.
• Experience with at least one of the following radios: Cellular, GPS, Bluetooth, Wi-Fi, Thread, NFC, or UWB.
