We are a U.S.based SaaS startup looking for a Senior Full Stack MERN Developer to work directly with our hands-on CTO.

- 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**:

- Opportunity to grow into a lead role as the team expands
