You will build the semantic layer essential for the next generation of autonomous enterprise agents. By extracting knowledge from fragmented data and constructing real-time AI Data Graphs, you’ll solve the context gap that causes 95% of AI pilots to fail, working directly with a world-class team of industry pioneers.
Senior Applied MLE at Series A AI context infrastructure startup
Enterprise AI is failing because agents lack business context. Join a Series A startup founded by the former Chief Architect of Visa and the creator of LinkedIn’s Skills Graph to build the missing semantic layer for the agentic era. As a Senior Applied MLE in San Mateo, you’ll tackle the hardest problems in knowledge extraction and AI Data Graphs, shipping directly to Fortune 500 customers and defining an entirely new infrastructure category. If you have 4+ years of experience in NLP and LLM fine-tuning and want to build the context engine that powers the next decade of AI, this is the role for you.
