Founding Engineer

We’re an AI-native lender and our team spent the first eight months of the business building completely novel in- house software: loan management systems, payment rails infrastructure, and technology for analyzing business bank transactions and financials. That foundation enabled us to raise over $100 million in funding for CPG brands within its first year. We’re now building the product that all of that infrastructure was designed to power: an AI CFO agent.

About the Role

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

1. 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
2. Improve agent trajectory quality, breadth, and depth of tools so the agent reliably ships magical, end-to-end outcomes
3. Compose existing scoped tools and build new ones (email composition, document filling, payload generation, account integrations)
4. Contribute to the underlying infrastructure that both the lending business and the AI agent business sit on top of
5. Operate as a tech lead from day one: ramp fast, own delivery, work in a Slack-native, AI-tool-heavy development cycle

Must-Haves

1. New grad to 5 years of engineering experience (hard cap at 5 years)
2. Excellence signal: notable startup background, big tech background, or top university CS / technical degree
3. Strong Python backend fundamentals: APIs, async, databases, cloud deployment
4. AI-native daily usage of Claude Code, Codex, or comparable agentic coding tools, with strong opinions on
5. how to make agent systems better
6. Self-motivated tech lead profile: ramps fast, works with minimal scaffolding, comfortable owning ambiguous
7. scope

Nice-to-Have
