## About the role

Cogentiq I2C is Fractal’s agentic AI Product for invoice-to-cash, covering Collections, Cash Application, Deductions, Invoice Management and Credit Risk. It runs on a Next.js front end, a FastAPI service layer, the Cogentiq agentic runtime, and a data tier on Azure Databricks with PostgreSQL.

## What they're looking for

- Ten to fourteen years building software, with at least three leading a team or a full product build
- Track record of owning technical design for a product, not only implementing someone else’s design
- Deep expertise in at least one tier, and enough working command of the others to lead, review and debug across all of them
- Strong Python, and production experience with FastAPI or an equivalent service framework
- Practical experience of a modern front end, typically React or Next.js, enough to hold the standard even if you are not the primary developer
- Data engineering depth: Spark and Databricks, Delta Lake, SQL, and sound judgement on what belongs in a lakehouse and what belongs in PostgreSQL
