About The Position

Our client is a fast-growing, venture-backed AI startup building foundational infrastructure that makes unstructured documents computable and queryable—similar to how relational databases transformed structured data. Their production-grade APIs process and structure millions of pages weekly for enterprise customers, including large financial institutions and publicly traded companies. The platform transforms complex formats (PDFs, PowerPoint, Excel, and more) into structured outputs optimized for LLMs and AI agents—powering high-stakes workflows across industries such as finance, legal, and healthcare. With $7.5M raised and a lean founding team, they are at an inflection point—scaling both product and infrastructure to meet rapidly increasing demand. This is an opportunity to join at the ground floor and play a defining role in shaping the company’s technical direction.
