Job Description:

Playlab seeks a Senior Fullstack Engineer to join our growing Engineering team. As a Senior Fullstack Engineer you'll be exploring and pushing the boundaries of what AI-native experiences can be - inventing new interfaces for AI interaction, building the tools that let educators create without code, and implementing the systems that help schools deploy at scale.

Job Responsibility:

  • Ship end-to-end features across the full stack - from React/Remix frontend to Node.js backend to integrations with Python AI services
  • Move fast to learn what works - ship small experiments quickly, then invest in productionizing what proves valuable
  • Stay on top of web technologies and best practices - evaluate new tools and patterns that improve the product
  • Work cross-functionally with designers, ML engineers, product, and customers to build experiences that solve real user needs
  • Write comprehensive tests and documentation for the features you build
  • Collaborate strongly with peers through code reviews and pairing

Requirements:

  • 5+ years building production web applications across frontend and backend
  • Strong experience with modern React frameworks (we use Remix) and TypeScript
  • Strong experience building backend services with Node and Typescript
  • Experience with databases, APIs, and integrations with external services
  • Able to work effectively with designers and translate designs into working features
  • Comfortable working cross-functionally and directly with customers to understand their needs
  • Thrive in high-agency, high collaboration cultures
  • Great communication that makes working remote-first work

Nice to have:

  • Experience designing or building AI-powered interfaces
  • Experience with educational technology or mission-driven organizations
  • Experience with Remix or similar React frameworks
  • Knowledge of accessibility and internationalization best practices
  • Experience integrating with LMS platforms or educational systems
  • Background in real-time collaborative features (WebSockets, CRDTs, etc.)
