Senior Full-Stack Developer Consultancy — ADT Studio (Remote / Home-based) Req no: 592323

UNICEF works in some of the world’s toughest places, to reach the world’s most disadvantaged children. To save their lives. To defend their rights. To help them fulfil their potential. Across 190 countries and territories, we work for every child, everywhere, every day, to build a better world for everyone. And we never give up.
The Global Learning Innovation Hub under the UNICEF Office of Innovation is seeking a Senior Full-Stack Developer to join the Accessible Digital Textbooks (ADT) team. The ADT initiative transforms PDF textbooks into rich, accessible digital learning materials for children with and without disabilities. The selected consultant will take the lead on the continued development of ADT Studio — a TypeScript monorepo application that automates the production of accessible digital textbooks through AI-powered pipelines. This role is central to making educational content universally accessible and available to millions of children worldwide.
The ADT initiative converts PDF textbooks into structured, accessible digital content — including HTML storyboards, quizzes, glossaries, image captions, translations, and text-to-speech audio — packaged as self-contained web bundles, EPUBs, or WebPubs. The production pipeline is powered by Large Language Models (LLMs) and controlled through a configuration-driven architecture that supports per-book customization of text classification, rendering strategies, and model settings.
ADT Studio is the successor to ADT Press, rebuilt as a TypeScript monorepo using AI-assisted development (Claude Code). It represents a significant architectural advancement: a two-level DAG pipeline model with a React frontend and Hono backend. The codebase is open-source, hosted on UNICEF’s GitHub, and designed for extensibility by third-party developers and country offices.
