We’re looking for a highly skilled N8N expert to design and build complex, production-grade automation workflows.
This is not a basic Zapier-style task. We need someone who can architect robust systems, connect multiple APIs, write custom code where required, and integrate AI models into real business workflows.
What You’ll Be Doing:
Design and build advanced N8N workflows from scratch
Connect and orchestrate multiple APIs (REST, webhooks, OAuth, custom auth, etc.)
Write custom JavaScript code inside N8N nodes when needed
Integrate AI models (OpenAI, Claude, etc.) into workflows
Handle data transformation, branching logic, retries, and error handling
Set up logging, monitoring, and scalable workflow structures
Work with GTM tools (CRM, enrichment, outbound, analytics, etc.)
Optimize workflows for reliability and performance
Example Use Cases:
AI-powered lead enrichment and qualification
Automated outbound personalization workflows
Multi-step data sync between CRM + internal DB + external tools
AI-driven content generation and routing systems
Internal ops automations with complex logic trees
Requirements:
Deep experience with N8N (not just basic automations)
Strong understanding of APIs (REST, auth flows, rate limits, pagination)
Ability to write clean JavaScript within N8N function nodes
Experience integrating AI APIs into production workflows
Understanding of GTM systems (Salesforce, Apollo, Clay, etc.)
Ability to think architecturally, not just tactically
Nice to Have:
Experience deploying N8N (self-hosted, Docker, scaling)
Database experience (Postgres, Supabase, etc.)
Webhook-based system design
Prior experience building AI-native automations
Engagement Details:
Project-based to start (with potential for ongoing work)
Clear scope and milestones
Fast decision-making and direct collaboration
When applying, please include:
Examples of complex N8N workflows you’ve built
APIs and AI models you’ve integrated
A short explanation of the most technically challenging automation you’ve built
