Senior Full Stack AI Engineer
Location: Remote – Mexico
Schedule: EST

About the Role

We are looking for a Senior Full Stack AI Engineer to join a US-based startup building an AI-powered back-office platform for the skilled trades.
This is a highly hands-on engineering role for someone who can own systems end-to-end — from modern React and React Native product experiences to Node.js services, AI agents, RAG/search, integrations, and production infrastructure.
The adecuado candidate is a strong product engineer who has already shipped production full-stack systems and has meaningful hands-on experience building AI/LLM-powered features.

What You’ll Build

New product screens and workflows for jobs, customers, invoicing, scheduling, and other business operations using React and React Native
AI-powered chat experiences including streaming responses, tool-result rendering, human review, and feedback loops
Production AI workflows including tool-using agents, RAG/search, classification, extraction, and human-in-the-loop systems
Backend APIs and services using Node.js and TypeScript




Business automations powered by AI
Integrations and data ingestion from third-party APIs, webhooks, and files
Evaluation and monitoring systems for AI workflows, including regression testing, quality metrics, drift detection, and cost/latency tracking
Scalable systems involving queues, orchestration, retries, data modeling, and API design
Reliable and polished user experiences with attention to performance, loading states, accessibility, and edge cases
Responsibilities

Analyze product and business requirements and propose practical, AI-native technical solutions
Design and ship full-stack features across React, React Native, Node.js, and AI services
Build clean, scalable, production-ready code
Design and implement LLM-powered workflows and AI integrations
Test, deploy, monitor, and optimize production systems
Evaluate AI-generated solutions critically rather than relying on them blindly
