Description
About the Role We are building a next-generation AI-powered intelligence platform designed to transform unstructured human activity into structured, measurable, and actionable insight. This is not a feature delivery role. We are looking for a deeply technical Product Manager who can operate at the architecture level — partnering directly with our AI Data Architect and engineering team to design, refine, and scale the core intelligence infrastructure of the platform. You must be comfortable discussing backend systems, data modeling, vector representations, scoring engines, routing logic, and deterministic workflows — not just timelines and tickets. If you have ever designed the spine of a system rather than just shipped features on top of one, this role is for you. What You’ll Be Working On This platform includes: ● Structured signal ingestion from unstructured inputs (language, behavioral activity, events) ● Vectorization and embedding pipelines ● Deterministic classification and routing systems ● Quantified scoring and measurement frameworks ● Identity and authority modeling systems ● Automated activation and intervention logic ● Feedback loops that measure outcome effectiveness ● Strict architectural constraints to prevent system sprawl You will help design and scale the infrastructure that powers these capabilities.
