Lead design and verification of high-speed analog and mixed-signal circuits (ADCs, DACs, PLLs, TIAs, SerDes, optical drivers) through tape-out and post-silicon bring-up in advanced FinFET or SOI processes. Collaborate cross-functionally, create documentation, present to leadership, and mentor junior designers.
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 Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
- Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
- Key Industries: Artificial intelligence, adtech, media, software, game development
- Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
- Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
- Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
