Porters is building the operating system for autonomous banking, and process accuracy is our moat. We are processing tens of thousands of documents per month, deriving instructions for banks to act on. We are looking for an AI Systems Engineer to perpetually increase our AI accuracy, move ideas from the “lab” into production in our high-volume pipeline. Your goal is 99.99% accuracy on very complex document types.

Mission: lead the systematic R&D required to tune LLMs for high‑stakes document types (e.g., insolvency notices, seizure orders), ranging from improved prompting via rethinking our AI document extraction approach to fine‑tuning models.
