Our requirements

  • Strong experience with React
  • Strong experience with FastAPI

Your responsibilities

  • You'd own the application end to end. Part of it is standard fullstack work: React on the frontend, FastAPI on the backend. The other part is building the agentic AI that the product is built around — agents that reason, use tools, and complete tasks on their own.
  • You'd lead the application code, working alongside experienced infrastructure and product engineers. We keep meetings and busywork to a minimum so you can actually focus.

About the project

Senior Fullstack Engineer
We're an early-stage startup building an agentic AI platform for security and compliance — software that automates a lot of the manual work those teams do today. The product is new, and you'd be one of the first engineers on it, with real input into how it's built.
