This is the title and if you click the link, you will have the duties listed. The one caution I'd have is that being in disaster recovery, you could end up on the road — a significant amount of time. While every FEMA position has this "Emergency Assignment" stipulation — see below — in recovery you could have a much more significant number of deployments. Just look at the number of disasters that are popping up everywhere in the United States. But, if you are looking to be in the field of emergency management, this would be a good place to start, when you are young and don't have family responsibilities.
EMERGENCY ASSIGNMENT: Every FEMA employee has regular and recurring emergency management responsibilities, though not every position requires routine deployment to disaster sites. All positions are subject to recall around the clock for emergency management operations, which may require irregular work hours, work at locations other than the official duty station, and may include duties other than those specified in the employee's official position description. Travel requirements in support of emergency operations may be extensive in nature (weeks to months), with little advance notice, and may require employees to relocate to emergency sites with physically austere and operationally challenging conditions.
