Job Listing Aggregator

## Job Aggregator Setup

1. **APIs**: This workflow fetches jobs from RemoteOK and ArbeitNow (public APIs).
2. **Normalization**: The Code node standardizes the JSON structure from both sources.
3. **Filter**: Only keeps jobs with "Engineer" or "Developer" in the title.
4. **Storage**: Saves results to Google Sheets (upsert based on URL).

**To Configure:**
- Connect your Google Sheets account.
- Create a sheet with headers: `title`, `company`, `url`, `source`.
- Connect Slack for error notifications.
