n8n Workflow Developer for AI Automation

The work

You will help train and evaluate AI systems that build complex n8n automation pipelines. The work combines prompt and response writing, technical evaluation, coding, and improvement of AI-generated workflows.

• Create prompts that test n8n workflow design, including nodes, execution patterns, error handling, retries, and data parsing.
• Review and rate multi-step automation pipelines against clear technical criteria.
• Improve AI-generated workflows for reliability, scalability, performance, sequencing, rate limits, and timeouts.
• Design automations that connect multiple services through APIs, webhooks, OAuth, API keys, and mapped data.
• Work on use cases such as AI content workflows, lead generation and outreach systems, and web scraping pipelines.
• Evaluate scraping workflows, including extraction reliability, parsing, and structured or unstructured data handling.
• Process and transform JSON, CSV, and HTML data, including validation and normalization.
• Use your n8n expertise to support prompt writing, evaluation and rating, fine-tuning, reinforcement learning from human feedback, and coding tasks.
