About the product

Titan is an AI-powered learning platform for Dutch secondary education (VMBO/HAVO/VWO). Students work through curriculum topics per subject — biology, Dutch, English maths, and so on - and get a personal AI tutor for each topic that answers questions and guides them through the material. As they go, they make exercises that are automatically assessed (open and multiple-choice), tagged against real didactic metadata like Bloom levels, learning objectives and difficulty. Schools, teachers and content sit behind it, with an admin panel for managing curriculum content. WeAreBrain built the platform for a Dutch client, and it's live.

About the role

We're handing Titan over to a developer who will own it day-to-day: backend, frontend, and the client relationship. You work directly with the client and translate their ideas into working software — but you're not on your own: the WeAreBrain team that built the platform stays available for advice, brainstorming, and architectural sparring.



They just won't be in the day-to-day work or client meetings; that's yours.

Technical stack:
API: Python / FastAPI, SQLAlchemy + Alembic, PostgreSQL, Docker

Web app: React 19, TypeScript, Vite, TanStack (Router/Query), Tailwind, typed OpenAPI client

Admin panel: Next.js / React (a smaller surface — comfortable React skills cover it)

AI layer: the tutor agent is built on Sinas, an open-source self-hosted platform for AI agents; the agent's configuration and behavior are part of the product you'll shape

Responsibilities:
Build new functionality across the full stack — primarily the API and web app

Evolve the product workflow: changes to the AI tutor's configuration, the API, and the frontend/UX as one coherent whole

Build dashboarding/reporting for the client

Keep the platform healthy
