About Fig
Fig is the AI platform for industrial ingredient manufacturers, the $750B industry that makes the ingredients in every food you eat. Some of the top ingredient businesses in the US are already on the platform and demand is pulling us forward faster than we can hire. Backed by Innovation Endeavors alongside angels from Instacart and foundational model labs who bet on this team.

The role
You'd join our founding engineering team, working directly with the founders every day and in every major decision the company makes. Some days you'll build backend systems that ingest hundreds of PDFs from customer ERPs and inboxes. Other days you'll build an agent that completes a 100 page food safety document. Frontend, backend, infra, agents. Everything is fair game.

The team
You'd work daily with founders out of Stanford, Instacart, Nature's Fynd, and Bain, plus a CTO who was the first engineer at two startups before this one. Between us: multiple successful tech companies and a multigenerational food manufacturing business. It's the rare room where deep AI talent and deep ingredient industry roots sit at the same table.

How we build
Kotlin and Spring Boot, React and NextJS, Postgres, GCP, Gemini and Anthropic, plus a healthy stipend for coding agent(s) of your choice. Intentionally simple. We'd rather go deep on a small set of tools than spread thin across a trendy stack.

Who wins here
A builder. You've shipped products real people used and you can explain what you'd do differently. You'd rather ship something 80% right today and iterate tomorrow than debate architecture for two weeks. If you enjoy rolling up your sleeves and diving into unknown territory, you'll feel at home at Fig.

We don't care where you went to school or how many years you have. We care about what you've built and how you think.
