Sr. RFIC Layout Engineer

San Diego, California, United States


Role Number:200464561
The Wireless SoC Radio Team designs state-of-art highly energy efficient CMOS radios, from RF to bits. To deliver these radios, our team is responsible for the design of a wide range of RF, analog, and mixed-signal blocks from RF front-end amplifiers to data converters, including baseband filters, baseband and RF phase-locked loops, crystal oscillators, and bandgap references. We are working on new technologies that transform the user experience at the product level, all of which is driven by a world-class vertically integrated engineering team spanning RF/Analog architecture and design, Systems/PHY/MAC architecture and design, VLSI/RTL design and integration, Emulation, Design Verification, Test and Validation, and FW/SW engineering. In this role, you will work closely with the RFIC design team to layout and verify custom RF and analog IP for complex SoC products. You will have a critical impact on developing Apple’s state-of-the-art radios and getting them into hundreds of millions of products.


As a RF IC Layout Engineer, you will be a key member of a small RFIC team, researching, designing and bringing the next-generation of wireless technologies into high-volume production in advanced CMOS technology nodes. Responsibilities include: - Detailed transistor-level layout of RF and analog circuit blocks including LNA, mixers, PLL, LO generation, modulators, power amplifiers, ADC/DAC, baseband filters, and bandgap/bias/LDO. - Block level and top-level layout through full verification flow including extraction, DRC, LVS, and DFM checking - Co-work with designers on block level and top-level floorplanning. - Layout review for power/gnd routing, electromigration, signal path check, differential and IQ matching, and signal coupling. - Top-level layout integration and verification, schedule management.

Minimum Qualifications

  • Knowledgeable in layout techniques for device matching, minimizing parasitics, RF shielding, and high frequency routing.
  • Solid understanding of RC delay, electromigration, and coupling.
  • Understanding of guard rings, DNW, PN junctions, and advanced process effects such as LOD, WPE, etc.
  • High level proficiency in interpretation of CALIBRE DRC, ERC, LVS, etc. in FinFet Technology.
  • Knowledge of CADENCE layout tools.
  • Excellent communication skills and able to work with cross-functional teams.
  • Capability to lead other layout engineers for top-level integration.
  • Ability to recognize failure prone circuit and layout structures and proactively work with circuit designers for the best approach to resolve problems.
  • Scripting skills in PERL or SKILL are a plus, but not required.
