Automate Job Opportunity Digests with OpenRouter, GPT-5, and Email

This n8n workflow automates the process of generating and sending personalized job opportunity digests. It leverages the power of AI to extract relevant information from job postings, summarize them, and deliver them directly to your inbox.

What it does

This workflow simplifies and automates the creation of job digests by:

1. Scheduling: Triggers at a set interval (e.g., daily, weekly) to check for new job opportunities.
2. Fetching Job Postings: Makes an HTTP request to an external API or website to retrieve a list of job postings.
3. Parsing HTML: Extracts structured data (e.g., job titles, descriptions, links) from the raw HTML content of the job postings.
4. Filtering Relevant Jobs: Applies a filter to narrow down job postings based on predefined criteria (e.g., keywords, location, role).
5. Summarizing with AI: Utilizes an OpenRouter Chat Model (e.g., GPT-5) via a LangChain Basic LLM Chain to generate concise summaries of each relevant job posting.
6. Structuring AI Output: Parses the AI-generated summaries into a structured format (e.g., JSON) using a Structured Output Parser.
7. Merging Data: Combines the original job posting data with the AI-generated summaries.
8. Formatting Email Content: Uses a Code node to dynamically generate the HTML content for the email digest, incorporating the summarized job opportunities.
9. Sending Email Digest: Sends the formatted email containing the job opportunity digest to a specified recipient.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• OpenRouter API Key: An API key for OpenRouter to access their language models (e.g., GPT-5). This will need to be configured as an n8n credential.
• SMTP Credentials: SMTP server details (host, port, user, password) for sending emails. This will need to be configured as an n8n credential.
• Job Board/API Endpoint: An HTTP endpoint or website URL from which to fetch job postings.
• Email Recipient: The email address where you want to receive the job digests.

Setup/Usage

1. Import the workflow: Download the JSON provided and import it into your n8n instance.
2. Configure Credentials:
   • Set up an OpenRouter API Key credential for the "OpenRouter Chat Model" node.
   • Set up an SMTP credential for the "Send Email" node.
3. Configure Nodes:
   • Schedule Trigger: Adjust the schedule to your desired frequency (e.g., daily, weekly).
   • HTTP Request: Update the URL to the job board or API endpoint you wish to scrape. You may also need to adjust headers or authentication if required by the source.
   • HTML: Review and adjust the CSS selectors in this node to correctly extract job titles, descriptions, and links from the HTML of your chosen job board.
   • Filter: Customize the filter conditions to match your specific job search criteria (e.g., item.jobTitle.includes('Software Engineer') && item.location.includes('Remote')).
   • Basic LLM Chain: Ensure the prompt for the LLM is tailored to generate the desired summary format.
   • Structured Output Parser: Verify the schema matches the expected output from your LLM chain.
   • Code: Modify the JavaScript code to format the email content as you prefer, including how the job summaries are presented.
   • Send Email: Update the "To" email address to your recipient, and customize the "Subject" and "From" fields as needed.
4. Activate the workflow: Once configured, activate the workflow to start receiving automated job opportunity digests.
