Most jobs that pay you would require you to be 18 in order to be paid the money and work for them.
You might be able to get a youtube partnership and earn money making good youtube videos.
You'd earn when your youtube video shows an advertisement to someone. But you'd need the videos to be really popular and if you're under 18 you'd need a parent other person 18 or older to sign up for the Adsense account that you would need to get paid through.
