## Description

We're hiring a Founding Engineer to work primarily on the new AI CFO agent. This role is tech-lead-level autonomy from day one. You will own and deliver on the agent's tool surface and trajectory quality, ramp up quickly without spoon-feeding, and operate as a self-sufficient builder. The time split is approximately 75% for new AI agent work and 25% for the existing lending infrastructure. The role is primarily backend Python, with exposure to TypeScript frontend development. No customer-facing work or formal product ownership is expected. You will be in the trenches building, but you will be socialized and excited about the product, not just talking to a database in a corner.
What You'll Own * Build and extend the AI CFO agent's tool surface so it can complete tasks that currently take a CFO or CEO an hour or more

 * Improve agent trajectory quality, breadth, and depth of tools so the agent reliably ships magical, end-to-end outcomes
 * Compose existing scoped tools and build new ones (email composition, document filling, payload generation, account integrations)
 * Contribute to the underlying infrastructure that both the lending business and the AI agent business sit on top of
 * Operate as a tech lead from day one: ramp fast, own delivery, work in a Slack-native, AI-tool-heavy development cycle
