Founding Engineer (CDI) | Accounts Receivable Automation – Paris - CDI

The Company

A company is building an AI-powered platform designed to fully automate accounts receivable and cash collection workflows.

Rather than a traditional SaaS tool, it develops an autonomous engine that connects directly to client systems and manages the entire process — from payment reminders to legal escalation — through intelligent, end-to-end workflows powered by LLMs.

The company is at pre-seed stage (~€1M raised) with a founding team of 3 and is entering a key phase of product construction.
