Hi @Massimiliano Scaraglino ,
It is not clearly stated in What's deprecated or removed from SharePoint Server Subscription Edition, but as far as I know, the workflow timer job is involved in managing the execution of SharePoint 2013 workflows. Therefore, the deprecation of SharePoint 2010 workflows will not affect the workflow timer job. But since SharePoint 2010 workflows will be deprecated, it is better to explore new solutions in advance. Microsoft recommends exploring SharePoint 2013 workflows or Power Automate as potential alternatives to SharePoint 2010 workflows.
Nintex Workflow Subscription is a third-party product and its compatibility with SharePoint Server Subscription Edition should be verified with the vendor.
Have a nice day! :-)
