Senior Mixed Signal Circuit Design Engineer
Analog & Mixed-Signal Design
Originally posted 1 September 2026 by the employer — open 9 days.
About the role
This role involves the design and implementation of high-speed Serdes architectures in deep-submicron CMOS and FinFET technology.
What you'll do
- Architect high-speed Serdes architectures and transistor-level builds to push data rates to 80Gbps and higher.
- Drive the entire lifecycle from initial concept and schematic entry to layout, verification, and final silicon characterization.
- Optimize complex circuits for system performance, balancing noise, power, and loop stability in deep-submicron nodes.
- Partner with layout engineers for strategic floorplanning and high-speed routing.
- Lead post-silicon bring-up and debugging efforts, translating real-world data into build refinements.
What you'll need
- MS in Electrical Engineering, Computer Engineering, or a related field, or equivalent practical experience.
- Minimum 5 years of professional Analog Build experience with FinFET and deep-submicron CMOS processes.
- Proficiency in the Cadence Virtuoso environment and simulation tools (Spectre, HSpice, FineSim, or XA).
- Expertise in noise analysis, Monte Carlo simulations, and complex loop stability.
- Experience in high-speed data and/or clock path design.
- Proven ability in modeling, timing, and functionality of analog and digital circuits for top-level verification.
