Role Overview

We are seeking a highly experienced Senior or Staff Analog/Mixed-Signal IC Designer to join a world-class semiconductor team. The ideal candidate brings deep expertise in high-speed analog circuit design—spanning wireline transceivers, RFIC front-ends, and precision data converters—and has a track record of delivering silicon in advanced FinFET or SOI processes. This is a high-impact individual contributor or technical lead role focused on next-generation silicon for data communications, wireless, and compute applications.


Key Responsibilities

  • Design and verify high-speed analog and mixed-signal circuits including ADCs, DACs, PLLs, clock distribution, laser/modulator drivers, and transimpedance amplifiers (TIAs).
  • Architect and implement wireline SerDes front-ends, optical interconnect ICs, and multi-GHz analog signal chains from concept through tape-out.
  • Develop transistor-level schematics and layouts in advanced FinFET (7–16 nm) or SOI technologies; collaborate with layout engineers to meet stringent PPA targets.
  • Drive pre-silicon simulation and post-silicon bring-up; analyze measured silicon data and iterate on design to close specification gaps.
  • Partner with digital, CAD, and systems teams to define mixed-signal partitioning, interface specs, and shared design methodologies.
  • Produce detailed design documentation and present technical progress to cross-functional stakeholders and leadership.
  • Mentor junior designers and contribute to best-practice development across the organization.

Required Qualifications

Education & Experience

  • Ph.D. in Electrical Engineering (or related) with 6+ years of analog/mixed-signal IC design experience, OR
  • MS. in Electrical Engineering (or related) with 8+ years of analog/mixed-signal IC design experience.

Core Technical Skills

  • Analog / high-speed circuit design: wideband amplifiers, comparators, bias networks, ESD-tolerant I/Os.
  • Laser/modulator drivers and transimpedance amplifiers (TIAs) for optical interconnect applications.
  • High-speed ADC and DAC design (pipeline, SAR, flash, current-steering); including low-speed (LS) converters for control and calibration planes.
  • Clocking systems: DLLs, resonant/CMOS clock distribution, fractional-N synthesis, jitter budgeting, oscillators (LC/Ring).
  • Hands-on design in advanced FinFET nodes (TSMC / Samsung 5–16 nm) and/or Silicon-On-Insulator (SOI) processes.

Preferred Qualifications

  • RFIC design experience: LNA, mixer, PA driver, Broadband amplifiers, RF front-end modules.
  • Familiarity with high-speed wireline PHY architectures (56G / 112G PAM-4 SerDes, NRZ).
  • Background in optical module ICs (TOSA/ROSA driver ASICs, coherent DSP interfaces).
  • Proficiency with Cadence Virtuoso, Spectre / APS / Ultrasim, and industry-standard layout tools.
  • Proficient in designing RF passives like transmission lines, inductors, Tcoils, etc using EM tools like EMX, Peakview, etc.
  • Lab characterization skills: oscilloscopes, VNAs, spectrum analyzers, BERT setups.
  • Publications or patents in analog/mixed-signal IC design are a plus.

What you need to know about the San Francisco Tech Scene

San Francisco and the surrounding Bay Area attracts more startup funding than any other region in the world. Home to Stanford University and UC Berkeley, leading VC firms and several of the world’s most valuable companies, the Bay Area is the place to go for anyone looking to make it big in the tech industry. That said, San Francisco has a lot to offer beyond technology thanks to a thriving art and music scene, excellent food and a short drive to several of the country’s most beautiful recreational areas.

Key Facts About San Francisco Tech

  • Number of Tech Workers: 365,500; 13.9% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Google, Apple, Salesforce, Meta
  • Key Industries: Artificial intelligence, cloud computing, fintech, consumer technology, software
  • Funding Landscape: $50.5 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Sequoia Capital, Andreessen Horowitz, Bessemer Venture Partners, Greylock Partners, Khosla Ventures, Kleiner Perkins
  • Research Centers and Universities: Stanford University; University of California, Berkeley; University of San Francisco; Santa Clara University; Ames Research Center; Center for AI Safety; California Institute for Regenerative Medicine
