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.
