This role at Apple involves designing and verifying high-speed, low-power analog and mixed-signal circuits. The team focuses on creating innovative clock distribution and data recovery circuits while ensuring robust performance across various conditions. Candidates will engage in transistor-level circuit design and block-level verification to meet stringent power and performance requirements. The position is based in Austin, Texas, and emphasizes collaboration and creativity in engineering solutions.

• Master's Degree or foreign equivalent in Electrical Engineering, Computer Engineering, Electronics Engineering, or related field.
• Experience in designing and analyzing high-speed analog and mixed-signal building blocks including PLL, LDO, ADC, DAC, and Phase-Interpolator.
• Familiarity with end-to-end SERDES systems including TX/RX design and channel characteristics.
• Proficiency in RTL/Verilog modeling for mixed-signal blocks.
• Experience with MATLAB for performance analysis of SERDES.
• Knowledge of testing equipment including spectrum analyzers, oscilloscopes, and signal generators.
• Experience in layout techniques for analog and high-speed circuits.
• Familiarity with signal processing for design and analysis.
• Proficiency in Python and Shell scripting for automation and data analysis.
• Experience with design validation tools including EMIR, static timing analysis, and DFT.

• Generate block and chip-level specifications for high-speed, low-power communication.
• Design complex analog and mixed-signal circuits at the transistor level.
• Conduct block-level simulations and analyses to verify circuit functionality.
• Design clock distribution circuits and CDR circuits for effective data recovery.
• Investigate power-efficient clocking architectures to minimize power consumption.
• Design and optimize Duty Cycle Correctors and Phase Interpolators.
• Design a 100MHz clock receiver with minimal jitter contribution.
• Test chips under various process, temperature, and voltage conditions for robustness.

• Employees at Apple are often offered comprehensive benefits that support physical and mental well-being—flexible medical plans, confidential counseling, onsite wellness centers at major campuses, and resources for fitness and daily life. Families typically receive fertility support, paid parental leave with gradual return, caregiving leave, and dependent-care guidance, while financial perks commonly include stock grants (with purchase discounts), 401(k) matching, and income-protection coverage. Employees also see robust time off, Apple University learning and tuition reimbursement, donation matching and paid volunteer hours, and deep product and partner discounts.
