Sr. Staff Engineer, ASIC Design Automation - CAD
Location: San Jose (on-site)

We are looking for an expert Chip Design Automation Engineer to architect and maintain the design automation and methodologies for our high-performance ASIC/SoC team. In this role, you will lead the definition and deployment of automated design flows for complex ASIC/SoC that integrate digital logic, custom analog circuits, and photonics components in leading-edge process nodes.
As a Senior Staff Design Automation Engineer, you will lead the development of new automation capabilities, optimizing existing methodologies, bridging the gap between EDA tools and the physical design team, and problem-solving to ensure smooth tape-outs.


Key Responsibilities
  • Flow Architecture: Architect, develop, and deploy robust automated flows for Synthesis, Place and Route (P&R), Static Timing Analysis (STA), and Physical Verification using industry-standard tools (Cadence/Synopsys).
  • Methodology Development: Drive improvements in design methodologies, specifically for high-speed digital and mixed-signal integration, hierarchical design planning, and signoff, ensuring high reliability and ease of use.
  • Tool Integration: Manage the installation, qualification, and regression testing of EDA tools and PDKs for advanced process nodes.
  • PDK & Tech Files: Customize and maintain technology files (LEF, TF, MMMC setups, DRC/LVS decks) to ensure compatibility between digital (Innovus/ICC2) and custom (Virtuoso) environments.
  • Automation: Develop advanced scripts and wrappers (Python, Tcl, Make) to streamline design execution, data management, and quality of results (QoR) tracking.
  • Flow Optimization: Analyze and optimize flow performance to improve runtime, compute resource usage, and license efficiency; identify bottlenecks and implement software solutions.
  • Support & Mentorship: Serve as the primary focal point for resolving complex tool/flow issues and provide technical guidance to junior engineers.
Basic Qualifications
  • BS or MS in Electrical Engineering, Computer Science, or related fields.
  • 5+ years of industry experience in Chip Design Automation.
  • Expert proficiency in scripting and automation using Python, Tcl, C-shell, and Makefiles.
  • Deep understanding of the complete ASIC physical design flow (Synthesis, P&R, CTS, Routing, STA, and Signoff).
  • Hands-on experience supporting major DEA tools (e.g., Cadence Innovus/Genus or Synopsys Fusion Compiler).
  • Experience managing PDKs and technology files for advanced process nodes (5nm or 3nm).
  • Proficiency with physical verification flows (Mentor Calibre, Synopsys IC Validator) and debugging rule deck issues.
  • Experience with version control systems (Git, Perforce) and workload management.

Preferred Qualifications
  • Experience developing Mixed-Signal flows (OpenAccess interoperability), bridging Cadence Virtuoso and digital P&R tools.
  • Experience with PDK development (P-cells, techfiles) or customizing DRC/LVS decks.
  • Experience with 3DIC/Chiplet packaging methodologies and co-design flows.
  • Background in photonics design automation or special custom circuit requirements.
  • Proven ability to work with EDA vendors to track feature requests and debug software bugs.
Salary range: $170,000 - $223,000

About Ayar Labs:

At Ayar Labs we’re about to revolutionize computing by moving data with light. We’re unleashing processing power for artificial intelligence, high performance computing, cloud and telecommunications by removing the bottlenecks created by today’s electrical I/O -- making it possible to continue scaling computing system performance. Ayar Labs is the first to deliver an optical I/O solution that combines in-package optical I/O chiplets and multi-wavelength remote light sources to replace traditional electrical I/O. This silicon photonics-based I/O solution enables chips to communicate with each other from millimeters to kilometers, to deliver orders of magnitude improvements in latency, bandwidth density, and power consumption.
With our strong collaborations with industry leaders and government, our deep ties to MIT and UC Berkeley, and our commitment to hiring the best engineers in photonics and electronics, joining our team gives you the opportunity to collaborate with renowned experts on challenging, paradigm-shifting work.
We are passionate about delivering in-package optical I/O at scale, leveraging the strength of our patent portfolio and our team of leading interdisciplinary experts. We believe that deep cross-collaboration between teams facilitated by honest, open debate is the best way to drive innovation and achieve big wins. Join our team and experience the possibilities.
