Talend Jobs support cross-platform execution. You can develop your Job on one machine, export the Job script, and then move it to another machine to execute without any additional configuration excepts the JDK installation.
For more information on how to build Jobs, see the Talend User Guides on Talend Help Center.
Starting from version 6.0, Talend Studio requires a JDK installation to build jobs completely.
For more information about JDK installation, see Requiring a JDK installation to build jobs starting from version 6.0.
