Senior n8n Automation Engineer — Ecommerce + Codex/Claude + Browser Automation

We are looking for a senior n8n automation engineer to build a production ecommerce automation system. The system should take an AliExpress link through the workflow of building ads and stores, launching, and reporting results. Existing store-building and video-creation capabilities will be provided; you will build the automation around the supplied business rules and policies and implement the remaining integrations and workflows. The system must manage multiple products at once across store setup, offer setup, creative ripping, payments/COGS, manual checks, ad deployment, testing, classification, reporting, and ongoing background automation. The core challenge is reliable parallel, long-running workflows. Multiple Codex, Claude, and Chrome/browser-based jobs may run concurrently, finish at different times, fail, wait for manual intervention, or continue in the background. The system must reliably track what completed, failed, or is waiting, and determine the next action without products interfering with each other. Required experience: n8n, browser automation, APIs/webhooks, asynchronous workflows, retries/concurrency, and production automation reliability. Shopify and Codex/Claude experience are strong pluses. All infrastructure, code, and workflows must remain company-owned. To apply, send 2–3 relevant systems you personally built, specify what you were personally responsible for, and share your availability. Shortlisted candidates will complete a paid practical test. Budget: $6,000 fixed-price project, paid through milestones.
