Humanitarian Jobs

During the past months as I have explored new career opportunities, I have seriously considered changing course and researching only humanitarian jobs. But how do you find good humanitarian jobs that actually can provide for your family as you serve those in more need than yourself?

I'm not sure humanitarian jobs are the way to support yourself financially, so having other sources of income would likely be the best way to begin, and then searching for ways to offer humanitarian service through humanitarian travel, charities, organizations, and volunteer work. There are so many opportunities to serve and so many needs around the world, but how do you know if you are getting involved in an organization that is run properly, where the money raised goes directly to those in need or if they go to pay for overhead costs, where the people involved are honest and have integrity?

If you have been involved with humanitarian service or know of humanitarian jobs, please share your experiences!
