Petit Larceny is a misdemeanor but if the case is not sealed it will show up on a background check. There are ways to get it sealed sooner assuming you plead to a non-crime.
I am a former federal and State prosecutor and have been doing criminal defense work for over 16 years. I was named to the Super Lawyers list as one of the top attorneys in New York for 2012 and 2013. No more than 5 percent of the lawyers in the state are selected by Super Lawyers. Martindale-Hubbell has given me its highest rating - AV Preeminent - in the areas of Criminal Law, Personal Injury, and Litigation. According to Martindale-Hubbell”AV Preeminent is a significant rating accomplishment - a testament to the fact that a lawyer's peers rank him or her at the highest level of professional excellence." Fewer than 8% of attorneys achieve an AV Preeminent rating. I also have the highest ranking – “superb” – on Avvo.

Unless you got juvenile offender treatment, this will most definitely show up on a background check. You should contact a lawyer to get a Certificate of Relief from Disabilities, which will help you when looking for a job.
It depends on the depth of the background check.
