Job Summary: We are seeking a hybrid developer to build interfaces and solutions with Supabase and AI for a startup in São Paulo. Key Highlights: 1. Hybrid approach combining low-code and high-code development 2. Development using Supabase and AI capabilities 3. Focus on data security and authentication About the Role: We are looking for a hybrid developer comfortable working across both low-code and high-code environments, to build interfaces and solutions using Supabase on the backend and AI capabilities (embeddings + LLMs). Our client is a startup located in the state of São Paulo. What skills does the client expect from you? * Develop interfaces and product workflows using low-code tools (FlutterFlow or Bubble). * Build web applications using high-code frameworks (React or Nuxt.js). * Implement backend services with Supabase (Postgres), including security rules and authentication. * Generate responses using LLMs within a RAG architecture. * Ensure security best practices (especially user-level data isolation). Technical Requirements **NOT** Mandatory: Low-code * Practical experience with FlutterFlow and/or Bubble. * Ability to implement UI logic and business rules on the frontend (state management, calculations, visual components such as cards and charts). Technical Requirements **MANDATORY:** High-code * Solid experience with React or Nuxt.js (project structure, components, API consumption, state management, UX). Supabase (essential) * Data modeling and usage of Postgres within Supabase. * Authentication (Supabase Auth). * Row Level Security (RLS): create policies ensuring each user accesses only their own data (with support for public content where applicable). * Creation/usage of SQL functions (RPC). * Experience with Supabase Edge Functions (Deno) for secure external integrations (e.g., calls to LLMs without exposing API keys). Bonus Qualifications: * Experience using AI tools in development (e.g., Cursor, VSCode with AI assistants, etc.). * Integration with LLMs for Q&A/assistants, ideally with source citations.
