Full Stack Engineer

Location: San Mateo, CA (In-Person, Bay Area) About Primepoint Primepoint is building construction intelligence for the physical world. We transform massive, static construction datasets (drawings, specifications, revisions, submittals) into an interactive, AI-powered system that surfaces conflicts, answers complex questions, and reduces schedule and cost risk on $100M–$3B+ building projects. We go beyond LLM wrappers. Our mission requires deep multimodal reasoning, document understanding, and applied computer vision at production scale. Our founders built Facebook’s first computer vision team and helped launch Facebook AI Research, and also founded startups in neural video compression (acquired by Apple). We are a technical team backed with $10M in seed funding and already working with paying customers spanning major hospital and large-scale commercial projects. We are in-person in San Mateo because we believe tight collaboration accelerates product velocity.
