Founding Engineer

About Butterbase

Butterbase (butterbase.ai) is an AI-native full-stack app platform: Postgres database, serverless functions, auth, storage, an AI gateway, and one-click deploys — built so both humans and AI agents can ship production apps fast. We're a small founding team with live product, real users, and a growing recipes ecosystem.

The Role

You'd be our founding engineer — the first engineering hire, working directly with the founders. You'll own core platform work end-to-end: design it, build it, ship it, operate it.

What you'll do

Ship core platform features across the stack (TypeScript, Node, Postgres). Build and harden the AI gateway and agent-facing APIs (LLM integrations, MCP). Own reliability, performance, and developer experience of the platform. Talk to users, turn feedback into product, and help set the engineering culture.

What we're looking for

3+ years building production full-stack systems (TypeScript/Node + Postgres or similar). You've shipped real products end-to-end and are comfortable owning ambiguity. Hands-on experience with LLM APIs or agent tooling is a strong plus. US-based, startup speed, extreme ownership.

What you get

$100K-$150K base + meaningful founding equity. Remote (US), founder-level ownership from day one. A seat at the table while the platform and company take shape.
