Principal Analog Mixed-Signal Design Engineer - Optical

Job Title

Principal Analog Mixed-Signal Design Engineer - Optical

Role Summary

Principal-level analog/RF design engineer responsible for architecture, transistor-level design and validation of high-speed optical receiver front-ends (TIAs) and related broadband analog circuits. The role is on the Broadband Analog team focusing on SiGe BiCMOS and advanced CMOS FinFET implementations for data center, metro and long-haul optical applications.

Primary mission: deliver leading-performance analog/RF IP and drive designs through tape-out, lab validation and transition to production.

Experience Level

Senior (Principal). Experience guidance: Master's or PhD holders typically 7+ years; Bachelor’s degree holders typically 10+ years of relevant industry experience.

Responsibilities

The role combines circuit design, layout-aware implementation, measurement correlation and cross-functional production handoff.

• Design active circuits for high-speed optical receivers, including transimpedance amplifiers (TIAs) and broadband drivers.
• Develop transmission-line and millimeter-wave structures to extend bandwidth and performance.
• Design broadband analog blocks (equalizers, AGC loops, linear regulators, current/voltage sensors, bandgaps, DAC/ADC interfaces).
• Perform analog custom layout and ensure layout-driven performance targets.
• Plan and execute post-silicon lab validation, correlate measurements to simulations, and debug silicon issues.
• Collaborate with functional teams for qualification, mass-production transition and customer support.

Requirements

Must-have technical skills and experience for immediate contribution.

• Proven track record in high-performance receiver design with successful chip tape-out and lab evaluation.
• Experience using EDA CAD tools for schematic, simulation and layout verification.
• Analog custom layout experience and layout-for-performance awareness.
• Experience measuring IC performance and debugging to correlate simulation and silicon results.
• Deep understanding of transistor-level design, device physics and control/feedback loop stability analysis.
• Strong written and verbal communication, presentation and documentation skills.
• Nice-to-have: experience with automatic gain-control loops, high-precision analog blocks (regulators, current sensors, bandgaps), continuous-time equalizers, package-system integration, and working with SiGe BiCMOS and FinFET technologies.
• Nice-to-have: experience leading chips to mass production, chip-lead responsibilities, and mentoring junior designers.

Education Requirements

Bachelor's degree in Electrical Engineering with 10+ years industry experience, OR Master's or PhD degree in Electrical Engineering with 7+ years industry experience. (Degree and years specified in the source.)
