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.


Role


Looking for a hands-on Founding Engineer to join at an early stage as one of the first technical hires, working directly with the CTO.




  • Build and ship product features from scratch to production




  • Design and implement end-to-end AI workflows (LLMs, agents, automation)
