How to Apply for 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 tech companies, they empower educators and students to build custom AI applications, with over 60,000 educators already using their platform. Working here means contributing to equitable educational futures while shaping AI as a 'new design material' for learning.

About This Role

As a Fullstack Engineer at Playlab, you'll build AI-native interfaces, creator tools, and real-time collaboration features that help educators and students create custom AI applications. This role directly impacts how 60,000+ educators implement AI in classrooms by shipping features across the full stack, from voice interfaces to mobile-first experiences. You'll be working on the core application builder where educators use natural language to create AI apps.

💡 A Day in the Life

A typical day involves collaborating with educators and product teams to understand classroom needs, then implementing features in the AI application builder. You might spend the morning refining a natural language interface for app creation, then transition to optimizing real-time collaboration features for multiple educators working together. The day often ends with testing mobile-first experiences and voice interfaces across different classroom scenarios.
