Hi
Welcome to Talend Community!
If using Talend Integration Suite(Commercial version), you can find Talend Administration Center(a web java application) to trigger, monitor Talend jobs periodically or conditionally. Besides, Talend has its own JobServer.
For Talend Open Studio, you can integrate Talend jobs with your own java application.
Here is a topic related to this issue. 2901
What's more, Talend supports deploying talend jobs as webservice.
Regards,
Pedro
