What We're Looking For

  • Curiosity and initiative to keep up with fast-moving AI and web technologies, evaluate what matters, and apply them in product work

  • Experience building web applications with React and Python.

  • Experience using Git and GitHub in a collaborative workflow.

  • Interest in AI application development, LLMs, automation, and emerging developer tools.

  • Ability to learn quickly, troubleshoot independently, and work in a fast-moving environment.

  • Strong communication skills and comfort working with both technical and non-technical teammates.

Preferred Experience

  • Experience with OpenAI APIs or other LLM APIs.

  • Experience with Supabase/PostgreSQL, edge functions, or serverless backend patterns.

  • Experience deploying applications on Vercel, AWS, or self-hosted platforms such as Coolify.

  • Familiarity with Docker, environment variables, secrets management, and basic production deployment practices.

  • Experience using AI coding tools such as Cursor, Codex, Claude Code, GitHub Copilot, or similar.

  • Exposure to prompt engineering, AI agents, RAG, workflow automation, or AI-powered internal tools.

  • A portfolio, GitHub profile, or examples of applications, prototypes, or experiments you have built.
