Mask Layout Designer

Contract – 6 months

Hybrid – San Diego, CA

Join a world-class engineering team driving innovation in RF, analog, and mixed-signal design for advanced SoC products. As a Mask Layout Designer, you’ll collaborate closely with circuit design engineers to create, optimize, and verify custom RF and analog IP – from low-noise amplifiers and mixers to PLLs, data converters, and baseband filters – used in high-performance consumer technologies worldwide.

What you’ll do:

• Perform 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.
• Execute block-level layout through full verification flow including extraction, DRC, LVS, and DFM checking.
• Collaborate with designers on block-level floorplanning.
• Conduct layout review for power/gnd routing, electromigration, signal path check, differential and IQ matching, and signal coupling.

What we’re looking for:

• BS degree with 7+ years of relevant industry experience.
• Experience in FinFET and custom RF/analog layout for radio transceivers with deep sub-micron CMOS knowledge.
• Solid understanding of RC delay, electromigration, coupling, guard rings, DNW, PN junctions, and advanced process effects (LOD, WPE).
• High proficiency with CADENCE layout tools and interpretation of CALIBRE DRC, ERC, LVS in FinFET technology (7nm preferred).
• Excellent communication skills and ability to work with cross-functional teams.
• Scripting skills in PERL or SKILL are a plus but not required.
