Lead Design Engineer

Company Overview

Prime Intellect makes frontier AI accessible to everyone. We are both a full-stack platform and an open research lab, enabling individuals and organizations to train their own models by directly leveraging our state-of-the-art agentic training infrastructure.

We believe in a future where the ability to produce domain-specific frontier AI is democratized, and where everyone company can be an AI company that builds, trains, deploys, and ultimately owns their own models.

We recently raised $15mm in funding (total of $20mm raised) led by Founders Fund, with participation from Menlo Ventures and prominent angels including Andrej Karpathy (Eureka AI, Tesla, OpenAI), Tri Dao (Chief Scientific Officer of Together AI), Dylan Patel (SemiAnalysis), Clem Delangue (Huggingface), and many others.
