How to Apply for Senior Fullstack Engineer

at Playlab

🏢 About Playlab

Playlab is a unique tech non-profit focused on AI in education, using an open-source, community-driven approach to empower educators and students. Unlike typical tech companies, they're building tools that help over 60,000 educators create custom AI apps without code, specifically for educational contexts. Their mission to make AI a 'design material' shaped by many for equitable learning futures makes this appealing for engineers wanting social impact.

About This Role

This Senior Fullstack Engineer role involves building AI-native interfaces that dynamically adapt from chat to writing editors to simulations based on learning moments. You'll be inventing new AI interaction interfaces and implementing systems for schools to deploy at scale, directly impacting how educators and students experience AI tools. The role pushes boundaries in creating no-code tools that help educators build custom AI applications.

💡 A Day in the Life

A typical day involves collaborating with educators to understand learning needs, then designing and implementing dynamic AI interfaces that might start as a chat but transform into writing editors or simulations. You'd be working on both frontend components that adapt to different interaction modes and backend systems that support scalable deployment across schools, while contributing to open-source tools that empower the educator community.
