We're helping a leading, early-stage stealth start-up building multi-agentic prediction software. Their mission is to predict human behaviour at scale. They're a small, nimble team looking for their Founding Product Platform Engineer to help lay the technical foundation for something extremely 'crazy'!

You will be instrumental in building the core product across frontend, backend, and data workflows. This means turning prototype scripts and one-off workflows into robust, reusable product systems. You'll build customer-facing interfaces for querying, exploring, and auditing AI-generated insights, and design clear product experiences for complex concepts like evidence, uncertainty, provenance, traces, predictions, and reports.

On the backend, you'll build APIs for customer workspaces, data ingestion, workflow execution, auth, and artifact retrieval, and design systems for storing source files, runs, outputs, traces, reports, evaluations, and provenance. Expect to create internal tools that make customer deployments faster and less manual, and own early deployment, observability, reliability, and security foundations.

You'll work closely with the Founding AI Engineer to productize AI workflows and with the founders to turn customer pain into product primitives, helping to define their engineering standards, architecture, and product culture.
