Any work you do and earn money is a Job.
Your options are limited. Most businesses want you to be 16 to hire you for gainful employment.
Time to be inventive,
My suggestions to you:
Make up fliers and pass them around in your neighborhood.
Offer to do whatever work it is you want to do, such as :
Computer work, Babysit, Clean Garages, Organize Cupboards, File Papers, Wash Cars, Mow Lawns, Pull Weeds, Tutor the neighbors kids, wash Dogs, Dog sit, Clean the Pool, Assist the elderly, whatever…
Post first whatever it is you want to do or are good at …
However, You should keep your options open and make a decision after the persons call you instead of not giving them many reasons to call.
Say you are a student and available on weekends and all summer.
Your neighbors who might hire you do not have to be residents, they might be local businesses that need a little job done. Do not be afraid to ask and apply. You won’t get a job if you don’t try.

Happy (early) Birthday! Perhaps jobs such as mowing neighbors’ lawns, washing cars, dog walking, sweeping driveways, even child care if your family knows the people though please only proceed with caution and go with one’s gut feeling. It’s usually safer to do money transactions outside of the neighbor’s home (except for child care which one usually needs to enter the home).
Please disregard the ‘work at home’ ads as just about all are scams especially if asking for money upfront or for personal information which can put one at risk for identity theft: http://www.ftc.gov and can click ‘identity theft’ or such.
