Responsibilities

• Collaborate with our product development teams (system, packaging, digital, photonics) to translate system-level requirements into electrical design specifications down to the block and micro-architecture level
• Working closely with our system-level architects, contribute to circuit-level assessments and design tradeoffs for high performance electro-optic data links
• Design of high speed data rate communications blocks including electrical SerDes,  sub-components such as PLLs, CDRs, digital or analog equalizers and optical transceivers
• Work closely with the physical design group to integrate analog IP at the chip level
• Define and run top-level verification and modeling of analog and mixed-signal systems from behavioral model to transistor level
• Define test plans (validation/characterization/debug)
• Mentor junior engineers

• BSEE minimum, PhD preferred with 12+ years of analog and mixed-signal design experience 
• Hands-on experience with the design of high-performance low-noise linear TIAs and drivers for silicon photonics modulators at 112G and 224G PAM-4 data rates
• Hands-on experience with link budget modeling and tradeoffs for electro-optical links
• Experience with developing mixed-signal products based on advanced FinFET foundry process nodes
• Hands-on experience with Cadence design tools for circuit design and simulation including corner and Monte-Carlo simulations
• Experience with multiple successful mixed-signal product designs released into volume production meeting target performance and yield requirements
• Excellent understanding of design and layout techniques to optimize for speed, power including minimizing noise and crosstalk in high-performance circuits
• Excellent understanding of noise, jitter, layout parasitics, mismatch, and design tradeoffs

• Comprehensive Health Care Plan (Medical, Dental & Vision)
• 401k matching
• Life Insurance (Basic, Voluntary & AD&D)
• Generous Time Off (Vacation, Sick & Public Holidays)
• Paid Family Leave
• Short Term & Long Term Disability
