Analog & Mixed-Signal Design
Originally posted 29 December 2025 by the employer.
About the role
This role involves end-to-end ownership of analog building blocks, from architectural definition through silicon validation, with a focus on high-performance Driver and TIA circuits in BiCMOS and advanced semiconductor nodes.
What you'll do
- Architect and design high-speed analog and mixed-signal circuits, including Transmit drivers, Transimpedance amplifiers (TIAs), receiver front-ends, Clocking and timing circuits (PLLs, DLLs, low-jitter references), Biasing networks, bandgaps, and on-chip power regulation.
- Perform transistor-level design, simulation, and optimization across PVT corners.
- Analyze and optimize bandwidth, noise, linearity, jitter, stability, and power.
- Collaborate with layout engineers on floorplanning, matching, isolation, and parasitic management.
- Define and support silicon bring-up, characterization, and debug, including correlation to simulations.
- Contribute to design methodology, IP reuse, and best practices across programs.
What you'll need
- MS or PhD in Electrical Engineering or related field.
- 7+ years of hands-on analog or mixed-signal IC design experience.
- Strong fundamentals in feedback and stability analysis, noise and jitter modeling, high-speed analog circuit design, power integrity, and substrate isolation.
- Experience taking Driver, TIA, or related analog blocks through tape-out and lab validation.
- Proficiency with industry-standard analog design and simulation tools.
Nice to have
- BiCMOS (SiGe) and/or advanced CMOS nodes.
- High-speed data-path or I/O-adjacent analog circuits.
- Experience with process scaling and technology trade-offs.
- Exposure to silicon debug, failure analysis, and yield learning.
Skills: high-speed analog, mixed-signal circuits, transmit drivers, TIAs, PLLs
