• Role: Engineering / Machine learning
• Experience: 1+ years
• Visa: US citizen/visa only

We use AI to mine discarded experimental data and drive scientific breakthroughs. Working alongside labs, we discover the materials that will power the new Industrial Revolution.

About 83 Sciences

83 Sciences (YC S26) is the intelligence engine powering the future of research and materials discovery. Most experimental data (failed runs, unpublished results, raw instrument output) never gets captured. We turn raw lab signals into novel discoveries: capturing and structuring experimental data, shortening research processes, and surfacing the insights that drive new materials.

The role

We're hiring a founding AI engineer to help design insight and discovery extraction models and ship tools for scientists. You’ll own the architecture and build the ML stack alongside our Chief Science Officer and work directly with the founders.

What you'll do

• Ship enterprise-ready products across our platform: data capture, structured experimental records, querying, and analysis tools
• Build our AI systems: multimodal pipelines (vision models for handwritten notebook pages and drawn structures, speech-to-text at the bench), agents that reason over a lab's full experimental history, and models that predict outcomes and propose optimized process conditions
• Work directly with research partners; watch scientists use what you built, then improve it
• Help shape model architecture, data pipelines, and technical direction as an early team member
• Build the data engine that turns messy experimental data (synthesis notes, PXRD, characterization) into training-grade datasets
