In a typical diversion program, if you successfully complete the program and probation the conviction is not entered. That is to say, there would be an arrest record, perhaps a record of a guilty plea, but technically no conviction. You should double check whether you have, in fact, been convicted of an offense before you fret about having to report a conviction to potential employers.
There are some occupations where full disclosure is the order of the day, even if your conviction was not entered (and even if you have obtained an expungement of the arrest records). For example, if you are asked about your encounters with the criminal justice system in association with a job which requires a government security clearance, you would be well-advised to tell the whole painful truth.
Recall that our current President has a drunk driving conviction and a conviction for disorderly conduct (or some analogous offense). Our Vice President has two drunk driving convictions. Assuming you have "turned your life around", most jobs will remain open to you even with a retail fraud / shoplifting conviction at the age of 18.
