Lead Full Stack Engineer

You will own platform features from data-model and service design through APIs and, where needed, the user interface. You will focus primarily on reliable, observable, scalable backend systems while setting standards for code organization, testing, API design, and deployment. You will prototype and ship AI-powered product features, build interfaces for LLM outputs and human-in-the-loop workflows, and make architectural tradeoffs between backend performance and frontend quality.
