Hi @sachin
I believe you can use the acf_form() with the “form” option set to “false”. This way, you can add ACF’s form to the existing job form. After that, you need to save the fields using the update_field() function. Please ask the theme author if they have an action hook to execute that function.
To learn more about ACF form, please take a look at this page: https://www.advancedcustomfields.com/resources/create-a-front-end-form/.
Hope this helps.
