Your job selection isn't necessarily limited by your major, especially if it is in liberal arts. Why are you majoring in Spanish? Do you like to speak the language, do you enjoy the literature, do you think you want to go to graduate school, etc.? Since you're not in college yet, you can always go in as a Spanish major and change majors later, if you want to. The easy answers are jobs like teachers, translators, etc., but the college you go to should have career counselors you can speak with that can help you identify your job prospects based on your major, your language skills, your interests, and a host of other items.
I minored in Spanish, and had the opportunity to work abroad for three years, then I've continued to use the language skills in my personal and professional life in communicating with people. I am glad I had another major, but I was really glad I developed those language skills.
