Job summary

Product Pulse is hiring a Founding Engineer to own the AI CFO agent workstream, with roughly 75% backend AI focus and 25% lending infra. You’ll lead delivery from day one, shipping end-to-end capabilities in a Slack-native, AI-tool-heavy development cycle.

The role targets new grads through 5 years of experience, requires strong Python backend skills and fluency with AI tooling, and favors zero-to-one startup builders in New York.

Qualifications

• 0–5 years of engineering experience (new grad to 5 years)
• Strong Python backend fundamentals: APIs, async, databases, cloud deployment
• AI-native daily usage of Claude Code, Codex, or comparable tools
• Top university CS/technical degree or notable startup/big tech background

Responsibilities

• Build and extend the AI CFO agent’s tool surface to enable tasks that used to take a CFO/CEO an hour or more
• Improve agent trajectory quality and breadth of tools to reliably ship end-to-end outcomes
• Compose existing tools and build new ones (email composition, document filling, payload generation, integrations)
• Contribute to the underlying infrastructure supporting both lending and AI agent surfaces
• Operate as a tech lead from day one with fast ramp, ownership of delivery, and a Slack-native development flow

Job description

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

• 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

Must-Haves

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

Nice-to-Have

Full-stack experience with TypeScript on the frontend

Prior zero-to-one startup experience with a clear story and demonstrable users High-frequency trading or quantitative engineering background (matches current team profile) Excited about UX and product, not just systems
