We're hiring a Junior Full Stack Automation Engineer who operates at the intersection of AI and production systems. You'll build, optimize, and scale AI-powered infrastructure across the full stack — from LLM pipelines and RAG systems to dashboards and background workers. This is a high-ownership role. You won't be handed tickets. You'll be handed problems and trusted to solve them.
WHAT YOU'LL BUILD & SCALE
AI Communication Pipelines
Classify inbound messages by category, intent, urgency, and tone
Generate contextual responses using enrichment data
Implement and tune human approval gates
AI-Powered Sales Intelligence
Transform raw enrichment data into structured pre-call briefs
Generate backgrounds, pain hypotheses, talking points, and rapport hooks
RAG System
Maintain and improve the vector database with embeddings
Implement markdown-aware chunking strategies
Build async ingestion workers and semantic search APIs
Trend Intelligence Engine
Process RSS feeds, social media, video platforms, and search trends
Generate reports, forecasts, and content drafts
Run autonomously on scheduled jobs
Content Quality Pipeline
Extend the multi-agent system (outline → audit → generate)
Maintain binary quality gates (PASS/FAIL with citations)
Support multiple content formats across the pipeline
Automated Lead Qualification
Enrich leads with product data and market insights
Build AI scoring and qualification grading systems
Generate automated audit reports
AI Executive Assistant
Build and maintain Slack-integrated operations
Automate scheduling workflows
Triage and respond to email autonomously
Build and improve AI pipelines for client performance insights
Improve RAG retrieval quality (re-ranking, chunking, hybrid search)
Add tool use / function calling for real-time data in LLM pipelines
Debug classification errors and improve model accuracy
Optimize LLM costs, latency, and performance
Build dashboards for AI metrics and usage monitoring
Add observability and tracing to AI pipelines
Expand content quality systems to new formats and use cases
Requirements
Required:
Production LLM experience — Claude or OpenAI deployed in real, live systems
RAG system experience — embeddings, retrieval, chunking, and context handling
2+ years TypeScript / Node.js
2-3 years building end-to-end production systems spanning backend services, AI pipelines, and frontend dashboards
Bachelor's degree in Computer Science
Strong React skills (component architecture, state management, performance)
PostgreSQL — queries, migrations, indexing, query optimisation
API integrations — REST, OAuth, webhooks
Linux server experience — SSH, log analysis, debugging, deployments
AWS Lambda, Terraform, and Docker experience
Available during Eastern Time business hours
Strong Pluses:
Multi-agent LLM systems and orchestration
Anthropic Claude expertise (prompt engineering, tool use, system prompts)
Vector search and embeddings (pgvector, Pinecone, or similar)
Slack API and bot development
Ad platform APIs (Meta, Google, LinkedIn)
LLM observability — cost tracking, tracing, monitoring
AI-assisted dev tools (Cursor, Claude Code, etc.)
Benefits
WHAT WE OFFER
High-impact role with genuine ownership over systems that matter
Salary from $2,500 - $3,500
Full time remote role
Work directly on one of the most advanced AI-native business platforms in the Amazon space
A team that moves fast, thinks big, and holds a high bar
PTO after successfully completed probationary period
