Osasco, Brasil Workana Tempo inteiro

Overview

We are a U.S.-based SaaS startup looking for a Senior Full Stack MERN Developer to work directly with our hands-on CTO. This is a senior role for someone who can not only ship features but also improve architecture, enforce clean code practices, and scale an MVP into a production-grade SaaS platform. We are prioritizing candidates based in Latin America (Argentina, Brazil, Colombia, Chile, etc.) to align with U.S. West Coast (Los Angeles) working hours.

Responsibilities
  • Take ownership of an existing MERN MVP and evolve it into a scalable, production-ready product
  • Refactor and improve messy or inefficient code for clarity, maintainability, and performance
  • Debug and resolve complex cross-layer issues quickly (MongoDB, Node.js, React, CI/CD)
  • Design and optimize MongoDB schemas, indexes, Atlas Search, and triggers
  • Build event-driven workflows with MongoDB triggers
  • Integrate AI/LLM services (OpenAI, AWS Comprehend, embeddings, NLP features) into production apps
  • Support and improve Twilio-based messaging and webhook integrations
  • Contribute to new product features end-to-end (backend + frontend)
Requirements
  • Expert in MERN stack: MongoDB, Express.js, React.js, Node.js
  • Deep MongoDB knowledge (indexes, performance, aggregation, triggers)
  • Strong backend/infra skills: Node.js async/memory, AWS (EC2, S3, Lambda), CI/CD pipelines
  • Experience integrating AI services into production apps
  • Excellent English communication (mandatory)
  • Availability during U.S. West Coast working hours (PST/PDT)
  • Based in Latin America (Argentina, Brazil, Chile, Colombia, etc.) for better time zone overlap
Benefits
  • Direct collaboration with a technical founder/CTO
  • Long-term role solving real production challenges (not just CRUD apps)
  • Remote role with U.S. time zone collaboration
  • Opportunity to grow into a lead role as the team expands
