Job description

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).

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.
• Lab characterization skills: oscilloscopes, VNAs, spectrum analyzers, BERT setups.
• Publications or patents in analog/mixed‑signal IC design are a plus.
