Job Title: Principal Analog Mixed-Signal Design Engineer - RF/SiPho/TIA/CMOS/SiGe
Location: Westlake Village, CA (Hybrid – Minimum 2 days/week on-site)
Employment Type: Full-Time, C2C Eligible
Salary Range: $145,300 - $215,010 per year

About the Role:
We are seeking a highly skilled Principal Analog Mixed-Signal Design Engineer with expertise in designing high-speed broadband ICs for optical data communication. This position offers a unique opportunity to work on cutting-edge technologies such as Transimpedance Amplifiers (TIAs) and Silicon Photonics (SiPho) for data center and telecom applications.

As a key member of the design team, you will play a critical role in designing innovative analog and RF circuits that push industry standards for performance and efficiency.

Responsibilities:

• Design and validate advanced broadband analog circuits for high-speed optical front-end receivers.
• Develop and implement FET and BiCMOS circuit designs with a focus on high-performance Silicon Germanium (SiGe) BiCMOS technology.
• Lead microarchitecture development for major circuit blocks and guide junior designers.
• Innovate in the design of linear regulators, AGC loops, current/voltage sensors, bandgaps, and more.
• Collaborate with cross-functional teams for post-silicon validation, product qualification, and mass production.
• Conduct layout and performance testing to ensure correlation between simulation and real-world results.

Required Skills & Qualifications:

• Education: Bachelor’s in Electrical Engineering; advanced degrees (MSc/PhD) preferred.
• Experience:
  • 10+ years in RF/Analog circuit design, including chip tape-out and lab evaluation.
  • Proven expertise in transistor-level design, control loop stability, and device physics.
  • Strong command of EDA tools and analog custom layout techniques.
  • Hands-on experience in AGC loop design, linear regulator design, and DAC/ADC integration.
• Technical Leadership: Ability to mentor junior designers and lead chip-level projects to successful silicon outcomes.

Preferred Qualifications:

• Proficiency in SiGe BiCMOS technology and CTLE design.
• Experience with system-package integration.
• Background in successfully taking chips to mass production.
• Strong communication, presentation, and documentation skills.

What’s Exciting About This Opportunity?

• Work with a market-leading team in delivering innovative solutions for data center and telecom networks.
• Contribute to groundbreaking designs that support AI connectivity in hyperscaler data centers.
• Competitive compensation package with RSU grants, annual bonus (17%), and relocation assistance.
• Be part of a culture that values purposeful and enduring innovation.
