Job description

Analog Mixed Signal SerDes Design Engineer

Cupertino, California, United States Hardware

We are seeking skilled Analog Mixed-Signal designers to join our high-speed SerDes team! Our team specializes in building next generation high-performance wireline transceivers delivering intellectual-property (IP) for Apple’s world-leading system-on-chip (SOC). In this role, you will actively work with cross-functional Analog Mixed-Signal design teams to create state-of-the‑art IPs key to Apple’s products. You will be challenged to make the best‑in‑class designs to surprise and delight Apple customers. With transforming the user experience in focus, you will get an opportunity to work on designs which makes the best systems. This enables you to learn end-to‑end system while exceeding the highest expectations of quality, innovation and efficiency. If you have strong fundamentals and a track record of tackling technical challenges, If you are passionate about learning new skills and improving the value of your work, If you like to be tuned to the bigger-picture while diving deeply into the details to innovate and solve problems, We invite you to join and grow with our team!

Description

We work on the development of high-performance and high-speed AMS circuits used in SerDes PHY, including evaluation of different circuit topologies for specific product requirements (e.g., Rx, CDR, Tx, bias generator, high-speed clock generation and low-jitter distribution, phase interpolator, DLL, VCO) with best-in‑class power, performance, and area (PPA). We work with cross-functional teams (e.g., architecture, SIPI, packaging, board design, DFT, ESD) to create block‑level specifications, and execute on transistor‑level implementation and behavioral modeling. We drive mask design to implement layout view of designs. We closely work with SOC teams to deliver IP views and make sure they meet the quality standards. While developing these complex IPs, on regular basis we interact with peers/management to communicate progress and discuss new insights making it a lively and interactive work environment.

Minimum Qualifications

• Bachelors/Masters in Electrical Engineering

Preferred Qualifications

• The ideal candidate should have deep understanding of AMS design with experience in high-speed serial links.
• Proven understanding and experience of designing analog mixed-signal circuit blocks including Bandgap, biasing circuits, LDO regulators, amplifiers, comparators, switched-cap circuits, ADCs, DACs, Oscillators, Filters
• Solid understanding of analog mixed-signal concepts like mismatch mitigation, linearity, stability, low-power and low-noise techniques
• Good grasp and understanding of digitally assisted analog design concepts (e.g. background calibrations, LMS based adaptive loops)
• Experience with high speed digital circuits (e.g., serializer, deserializer, counters, dividers, etc.) with the understanding of digital design concepts
• Knowledge of Tx/Rx equalization techniques and circuits (e.g. CTLE, DFE, de-emphasis) for 20+ Gbps NRZ and PAM applications
• Knowledge of CDR architectures and implementations
• Knowledge of lab equipments and testing
• Experience in AMS circuit modeling and performance evaluation (e.g. SystemVerilog, Matlab, Python, VerilogAMS)
• Hands‑on experience in advanced CMOS technologies, design with FinFet technology
