Tags: JavaScript CSS Python Front-end

Nuada is a startup selected by Startup-Chile (IGNITE), focused on AI agents for productivity and operations. We’re integrating our 4 core agents into a unified dashboard: NScaling.
You’ll join a small, senior team with weekly delivery cycles, code reviews, and strong emphasis on quality, security, and speed. We value technical curiosity, solid engineering practices, and the ability to turn business needs into scalable products.

Key responsibilities

Ship end-to-end features in NScaling (React/TypeScript front-end + Node/Express back-end), integrating the 4 AI agents.
Design and expose REST/GraphQL APIs, integrate third-party services, and model robust data (MongoDB).
Build Python tools/microservices for MCP (tools/servers/adapters) to enable agent orchestration and conversational workflows.
Apply LangChain/LangGraph patterns (pipelines, tools, evaluation, retries); use RAG/caching when appropriate.
Package with Docker, deploy to AWS/GCP, and automate CI/CD (GitHub Actions or similar).
Add observability (basic metrics, logs, alerts) and keep costs under control.
Enforce security: secrets management, OAuth/JWT, least-privilege, and data-protection practices.
Write tests (unit/integration), document decisions, and participate in code reviews.
Collaborate with product/UX to iterate fast and deliver value in weekly cycles.

Requirements and preferences

Required

Strong MERN foundation: React (ideally TypeScript), Node.js/Express, MongoDB, API consumption/creation.
Intermediate Python to create scripts/services, with willingness to deepen in MCP.
API design, front-end state management, basic testing, and Git/CI proficiency.
Cloud fundamentals (AWS and/or GCP) and Docker for packaging and deployment.
Clear communication, prioritization, and teamwork.
Fluent Spanish; able to read technical English.
Based in Chile (Santiago preferred) with availability for hybrid work (currently mostly remote).

Nice to have

LangChain/LangGraph, RAG, embeddings & vector DBs (pgvector/Supabase/Pinecone/Qdrant).
GraphQL, WebSockets/SSE, Next.js, Tailwind, shadcn/ui.
Observability (OpenTelemetry/Prometheus/Grafana), security (OAuth/OIDC), caching patterns.
Serverless, Kubernetes, IaC (Terraform/Pulumi).
Integrations with email/calendar/files and messaging (e.g., Gmail/SES/Calendar/Slack/WhatsApp Business).

Desirable skills

Prior hands-on with MCP tools/servers or equivalent integrations (adapters, gateways, tool-calling).

Real-world deployments on AWS/GCP with cost/security best practices.

Genuine interest in AI agents and user-centric product development.
