About Rain:
At Rain AI, we’re creating a future with abundant and scalable artificial intelligence. We're 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
As a Principal Engineer in Simulation and Modeling, you will collaborate with the software, architecture, and IC design teams to deliver high-performance software simulation tools that accurately model the functionality and performance of Rain’s hardware platform. These tools play a critical role in Rain’s internal software and hardware development efforts and will be deployed to end-users as part of the Rain SDK, allowing customers to experiment with Rain hardware early in the product development life cycle.
Through your efforts, our simulation tools will be easy to use, extensible, and will deliver maximum performance without compromising accuracy. This is a remote role – you can work from anywhere in the United States.
