Principal Analog ASIC Design Engineer

About Xanadu: 

Xanadu’s mission is to build quantum computers that are useful and available to people everywhere.

At Xanadu, we are learners, innovators, researchers, collaborators and problem solvers. We are creating something that has never been built before. What we are doing is extremely hard, the classic moon shot. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems and literally change the world. And that is something to be excited about!

Your role and responsibilities: 

We are looking for an experienced and driven ASIC Engineer to join our hardware team and contribute to the development of cutting-edge photonic quantum computing systems. If you thrive on tackling complex challenges at the intersection of high-speed analog, high voltage, and advanced semiconductor technologies, we want to hear from you!

This isn't your typical analog design job. We are building state-of-the-art photonic quantum computers, and this role is critical to controlling and reading out our core hardware. As our Principal Analog ASIC Design Engineer, you will define the architectural roadmap and own the entire lifecycle of custom ASICs built to operate in truly demanding environments. You will be solving unique, industry-first challenges at the intersection of high-speed (<10ns) and high-voltage (up to 100V) design. Critical blocks in the circuits you design and oversee will include ultra-low-noise transimpedance amplifiers and high-voltage amplifiers and drivers.

Key Responsibilities:

• Architecture & Strategy: Define the technical roadmap, architectural specifications, and methodology for novel, high-performance analog and mixed-signal ASICs to meet next-generation quantum computing targets.
• Vendor & Partner Management: Serve as the primary technical interface with tier-1 external ASIC design houses, guide them through process surveys, preliminary simulations, detailed design, and ultimately, tape-out execution.
• Internal Design Ownership & Tape-Out: Lead the design, top-level layout integration, and verification strategy for complex tapeouts, ensuring first-time-right silicon success for critical system blocks.
• Testing, Characterization & Debug: Oversee advanced lab characterization strategies, analyzing silicon performance against complex system requirements and driving the resolution of deep technical anomalies.
• Cross-Functional & Strategic Collaboration: Partner closely with photonics, packaging, and systems architecture teams to co-design and solve foundational system-level integration and scalability challenges.
• Technical Leadership: Mentor senior engineering staff, champion design best practices, and serve as the company-wide subject matter expert for analog IC design.

Basic qualifications and experience:

• Experience: 10+ years of professional experience in analog or mixed-signal ASIC/IC design, with a history of leading successful complex IC projects.
• Full-Cycle Leadership: A proven track record of steering multiple complex tapeouts from initial architecture definition through to successful silicon validation and system integration.
• Technical Mastery: Deep experience in designing highly challenging analog circuits simultaneously constrained by both high-speed (e.g., <10ns) AND high-voltage (e.g., 50V-100V) requirements.
• Process Versatility: Extensive design experience across multiple advanced semiconductor process nodes (e.g., BCD, SOI, GaN, BiCMOS) and the ability to strategically select the optimal process for quantum applications.
• Tool Proficiency: Mastery of industry-standard EDA environments (Cadence strongly preferred) along with the ability to define simulation and verification methodologies.
• Education: A Bachelor's or Master's degree in Electrical Engineering or a related field with a focus on IC design.
• Communication: Exceptional ability to synthesize complex technical concepts into clear documentation, design reviews, and strategic recommendations for both technical and non-technical stakeholders.

Preferred qualifications and experience:

• Photonics Experience: Direct experience architecting interface electronics for photodetectors, optical modulators, or co-packaged optics.
• Advanced Processes: Pioneer-level experience with High-Voltage SOI, RF Analog, or GaN process development and modeling.
• Advanced Education: A Ph.D. focused on a relevant IC design topic.
• Data Converters: Demonstrated experience architecting and delivering high-performance, custom DAC/ADC architectures.

This is for a new position. Your base salary will be determined based on your location, experience, and internal benchmarks. You will also be eligible for equity and benefits.
