Under administrator/language/en-GB/ you should have the files en-gb.com_tijobs.sys.ini and en-gb.com_tijobs.ini. In these two files, change the strings that give the name to your component. Examples of the strings that name your component:
COM_TIJOBS="Your Component Name"
COM_TIJOBS_COMPONENT_LABEL="Your Component Name"
COM_TIJOBS_TITLE_TIJOBS="Your Component Name"
You can also find the references in your database in the #__menu table.
