As a Full-Stack Developer you build the products our clients and their customers use every day: customer portals, internal tools, SaaS platforms and the APIs behind them. You take features from a rough idea to a polished interface backed by a sound data model, and you stay involved once they are live.
Many of these products include AI features, so you work closely with our AI engineers to put agents and search in front of real users in a way that feels clear and dependable. You write TypeScript on the front end, work comfortably in Python and Postgres on the back end, and review changes from colleagues and coding agents with care.
What you will do
- Build web applications and customer portals with Next.js and React
- Design data models and write APIs in TypeScript and Python
- Implement authentication, organisations, roles and billing for SaaS products
- Integrate AI features, third-party services and client systems
- Write tests and review pull requests from colleagues and coding agents
- Work with clients to shape features and agree on what goes live
What you bring
- Several years building web applications with TypeScript and React
- Experience with Next.js or a comparable full-stack framework
- Experience building APIs in Python or Node.js
- Good working knowledge of PostgreSQL and data modelling
- An eye for detail in interfaces, including accessibility and responsive layouts
- Clear written and spoken English
Nice to have
- Experience with FastAPI or Django
- Experience with Stripe billing or multi-tenant SaaS
- Experience building interfaces for AI features such as chat or search
- Dutch, for conversations with some of our clients
