How to Apply for Senior Fullstack Engineer

at Playlab

🏢 About Playlab

Playlab is a unique tech non-profit focused on democratizing AI in education through open-source, community-driven tools. Unlike typical edtech companies, they empower educators and students to build custom AI applications without code, with over 60,000 educators already publishing apps on their platform. Their mission to shape AI as a 'new design material' for equitable learning makes this appealing for engineers who want social impact alongside technical innovation.

About This Role

As a Senior Fullstack Engineer at Playlab, you'll be inventing AI-native interfaces and building the core application builder that allows educators to create AI apps using natural language. This role directly impacts how 60,000+ educators and their students interact with AI, pushing boundaries in real-time collaboration and adaptive learning interfaces. You'll be implementing systems that help schools deploy AI tools at scale while exploring novel interfaces for AI interaction.

💡 A Day in the Life

A typical day might involve collaborating with educators to understand their needs, then implementing features in the core application builder that allow natural language creation of AI apps. You could be designing dynamic components that adapt between different interface modes based on learning contexts, while also working on real-time collaboration features that enable multiple educators to build together. The work balances innovative AI interface design with practical implementation of scalable deployment systems for schools.
