About this job
Join a small, tight-knit product team building an AI-powered, autonomous accounting platform for the smallest businesses and the accountants who serve them. You'll own features end-to-end — from an idea in a conversation, through the API and data model, to what the customer actually sees and trusts. A core part of the work is building AI agents and the tools and workflows around them, in a product that's live in production, not a pilot. This is a Senior-level role. What you'll do - Build and improve the product experiences small business owners and accountants use every day - Develop backend services and integrations with the systems accounting runs on - Design and ship reliable AI-powered workflows (LLM APIs, tool calling, streaming, agent flows) where "usually right" is not good enough -…
This is a short summary.
