Will a juvenile show up and should I disclosed it on my application for a job with the county?

I was arrested when I was 16 for shoplifting. I think under $30. I went to the police station and fingerprinted and all then let go. I never appeared in court or pled to anything. My parents paid a fine and I did a booklet that was sent back somewhere. I'm 27 now and have done nothing since then. I'm supposed to start soon and no one I've talked to thinks it will show up in the background check. I've googled myself and went on the county clerk website. Noting came up. How else can I make sure? Will it show up or am I safe?
