Principal Analog Mixed-Signal Design Engineer

Job Title

Principal Analog Mixed-Signal Design Engineer

Role Summary

Member of the Optical / Broadband Analog group responsible for design and validation of high-speed optical front-end ICs, primarily multi-tens-of-GHz transimpedance amplifiers (TIAs) and related broadband analog circuits. The role includes hands-on circuit design, microarchitecture of major blocks, and technical leadership of a design team.

Work supports AI and hyperscaler data-center connectivity by improving bandwidth, capacity, and power efficiency of optical interface chips.

Experience Level

Senior — typically 10–15 years of industry experience for candidates with a Bachelor's degree; 5+ years for candidates with an MSc or PhD in Electrical Engineering.

Responsibilities

Primary responsibilities include circuit design, technical leadership, and cross-functional product development.

• Lead active circuit design and provide technical leadership for high-speed analog/RF products.
• Design transimpedance amplifiers (TIAs) and related equalizers, primarily in SiGe BiCMOS and CMOS technologies.
• Develop transmission-line and millimeter-wave structures to extend bandwidth and performance.
• Design broadband analog blocks (linear regulators, AGC loops, current/voltage sensors, bandgaps, etc.).
• Define microarchitecture of major circuit blocks and guide implementation by the design team.
• Support post-silicon validation, qualification, transfer to mass production, and customer support.
• Collaborate with layout, test, packaging, and system teams to resolve integration issues and correlate measurements to simulations.

Requirements

Must-have technical skills and experience are listed below; preferred items are noted separately.

• Must-have: Proven IC design experience including chip tape-out and lab evaluation of receiver/TIA designs.
• Hands-on experience with EDA CAD tools and analog custom layout.
• Experience measuring IC performance and debugging to correlate simulation and measurement.
• Deep transistor-level design knowledge, device physics, and control/feedback loop stability analysis.
• Experience with SiGe BiCMOS and CMOS technologies and millimeter-wave/transmission-line structures.
• Ability to lead design teams and drive technical decisions across the project lifecycle.
• Nice-to-have / strong plus: AGC loop design, CTLE experience, high-precision analog (regulators, sensors, bandgaps, DACs), package-system integration, prior chip-lead or mass-production experience, and mentoring junior designers.
• Strong communication, presentation, and documentation skills.

Education Requirements

Bachelor's degree in Electrical Engineering (RF/Analog/TIA design) with ~10–15 years industry experience, or MSc/PhD in Electrical Engineering with 5+ years industry experience. (Degree-level and years-of-experience guidance taken from the source.)
