Founding CTO – AI for Materials Discovery

Have you trained AI models for materials and shown a measured uplift? Join as co-founder and CTO.

A seed-stage AI-for-materials company in New York turns unpublished lab data from academia into new, synthesizable materials. Its seed round is closing. As co-founder and CTO you'd own the AI engineering and the data-and-discovery engine, and build the team after the round. For a top builder who isn't ready for co-founder risk, there is also a founding-engineer track.

What you'll own

- The AI engineering behind materials discovery, end to end - The data-and-discovery engine: data, architecture and measured uplift - Building and leading the engineering team after the seed

Must-haves

- You've built, trained and deployed AI models for materials (AI for biology or protein-structure work doesn't count here) - You build a model end to end, from data to architecture to measured uplift, and you're strong on data pipelines, not research only - You use frontier models in your work - 4+ years of real industry experience (roughly 4–10) - In person in New York, 9-9-6

Bonus points

- A materials model with a measured uplift from data you collected yourself - AI-for-science work at a leading lab, a commercial PhD or postdoc, or an AI-materials startup - A network you can recruit from

What's in it for you

- $120k–$500k base + 1–20% equity, depending on the track - A co-founder seat at the start of a new company

Good to know

- Full-time, in person in New York, 9-9-6 - Sponsorship is limited: please tell us your exact work authorization up front Process: screening with the CEO technical conversation take-home (a theory problem, 24 hours) with a follow-up final technical round with an advisor (coding challenge plus a deep conversation) a work trial of about a week in New York
