EDA/CAD Engineer, Characterization Specialist (US)

We are looking for an EDA/CAD Engineer specializing in characterization with 3+ years of experience to design and build a high-performance cell characterization engine from scratch. You'll be the kind of person who could have built PrimeLib or SiliconSmart, not just configured and run one. This is a rare opportunity to own foundational infrastructure end-to-end at an AI-native EDA startup that's rewriting the rules of physical design optimization. You'll work alongside a small, technically deep team of EDA and ML veterans with the kind of ownership and latitude that doesn't exist at large incumbent vendors.

What will you be doing?

• Design and build a fast, scalable characterization engine covering timing, power, and noise models for standard cells and custom IP, including NLDM, CCS, and ECSM model generation

• Architect the SPICE simulation orchestration layer with job scheduling, parallelization, and intelligent sampling techniques that minimize runtime without sacrificing accuracy

• Own liberty (.lib) file generation and validation infrastructure, ensuring outputs are correct and usable by downstream STA tools

• Collaborate directly with DeepWeave's physical design optimization and ML teams to define what characterization data the optimizer needs and build programmatic APIs for the optimization loop

• Make real engineering tradeoffs between speed and fidelity, and defend those tradeoffs to technically sophisticated customers
