Senior Analog & Mixed-Signal IC Designer

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.
