Senior AI Engineer

Here at Craftable, we create best-in-class technology for world-renowned bars and restaurants. We were founded in 2015 in Silicon Valley by tech experts and hospitality industry veterans. Since then, we have brought the best to Texas for a warm southern twist! Our goal is to collaborate with restaurateurs, operators, and accountants to reduce labor costs, increase efficiency, and drive profit for our clients.

Our platform is built to accommodate operators from independent restaurateurs to regional and national chains.

We re seeking a senior engineer to expand and enhance our hybrid RAG AI OCR system that processes invoices from major vendors like Sysco, Chef s Warehouse, and hundreds of other suppliers. You ll work on a system that combines cost optimization with accuracy improvements through intelligent prompt engineering and vector-based pattern matching.
