Federal government jobs are employment opportunities with national agencies and organizations. Elected positions are important in government, but non-elected civil servant jobs play a significant role as well. The military is one way to serve the country, but you can find a civilian job within a federal government department or agency. The qualifications and skills you need to be a civil servant vary depending on the position. Your job duties and responsibilities also depend on the civilian job you perform, such as economist, accountant, tax collector, criminal investigator, janitor, or secretary.
