About Rain: 

At Rain AI, we’re creating a future with abundant and scalable artificial intelligence. Were building the world’s most cost and energy efficient hardware for AI. Our products achieve an order of magnitude improvement over the status quo by co-designing every layer of the AI stack, from circuits to algorithms. Our ultimate goal is to become the dominant hardware company of the AI era.  

Rain AI is currently a Series A stage startup and backed by world leaders in AI. Our seed round was led by Sam Altman (OpenAI). In addition, our current VC partners include Y Combinator, Daniel Gross, Jaan Tallinn, Founders X Fund, Airbus Ventures, Liquid 2 Ventures and Deepwater. 

About the role: 

We are looking for a Principal Circuit Design Engineer to join our custom team. You will be designing and implementing low-power, high performance, area-efficient compute-in memory circuits and architectures. This is a highly visible role where you will closely collaborate with layout, CAD, physical design teams.  

Responsibilities: 

Develop custom digital circuits for novel high-speed and low-power compute-in memory designs
Work closely with the architecture and IC design teams to integrate SRAM macros into an in-memory computing accelerator  
Collaborate with an exceptional logic/architecture team to formulate design specifications 
Innovate and incorporate special circuits and features to achieve better PPA
Own validation, margin simulation, and characterization flows for block development and sign-off
Work closely with layout team for planning and support and review layout for optimality 
Participate in test chip design efforts to explore and validate new ideas and approaches 
Mentor, guide, and direct other designers, while being hands-on in digital circuit design

Qualifications:
