Senior Full Stack Developer, Node + React

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 Argentina or Brazil to align with U.S. West Coast (Los Angeles) working hours.

What You’ll Do

  • 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 Argentina or Brazil

    • 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
