Lead Design Engineer

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.

We are seeking a Lead Design Engineer to build and shape the product experience of how our users train and evaluate models on our platform.

This is a novel design space, and you’ll work directly with our research teams on shaping the experience between using our software frameworks, CLI tools, and platform to with the goal of making it as easy as possible for any software engineer to learn to train models, without needing prior knowledge of AI/ML research.

You’ll also interface with our talented design team on levelling up our platform aesthetics and brand.
