About the company and project:

ZONE3000 is proud to represent its partnership with Namecheap (www.namecheap.com).

What you'll actually be doing:

• Own the lead handover pipeline: when Email Bison fires a reply, bounce, or sequence-finished event, your n8n workflows update the client's Slack channel, their CRM, and our Clay Master Table simultaneously
• Build and maintain CRM integrations for whatever the client uses (HubSpot, Pipedrive, Salesforce, Attio, GoHighLevel, Dynamics 365, Monday.com, Airtable). New integrations live within 48 hours of assignment.
• Maintain the core general workflows: positive reply routing, unsub/auto-reply handling, mailbox management, daily volume reporting, weekly client reports, LinkedIn replies via HeyReach
• Run the mailbox lifecycle automation: import setup, ramp-up, warmup to ready transitions, EmailGuard placement tests, status tagging, and Slack alerts for damaged or disconnected mailboxes
• Monitor #errors and fix broken workflows same-day. Maintain error handling and retries in everything you build.

• Build internal tools and scrapers (Cursor + Claude Code) to replace paid services and streamline ops

   

You won't: talk to clients (the founder does), write campaign copy, source leads, or run campaigns. Your scope is the technical backend that makes the delivery team's work possible.

How we work: We hire for attitude and desire over long CVs and credentials. We use AI in every part of our delivery, which is how a lean team serves a growing number of clients without dropping quality. All internal communication happens in English since we serve clients mostly in the US and Europe.

Stack: n8n (self-hosted on Railway), Email Bison, HeyReach, Clay, Supabase, Slack, Cursor, Claude Code, Notion, Todoist.

Requirements: 2+ years building production n8n workflows (real webhook-driven, multi-branch, error-handled stuff, not tutorial-level), solid REST API and webhook fundamentals, comfort picking up any CRM API from docs, ability to debug end-to-end without hand-holding, extreme ownership, working knowledge of JavaScript (n8n Function nodes) and SQL (Supabase), and fluent use of AI tools in your daily work.
