All permanent Forest Service jobs (along with other federal jobs) are advertised through the Office of Personnel Management's USAJOBS website. You can search the openings by agency, by location, by salary range or by "series", a system for identifying the type of work. Many positions are only open to current Federal Employees; if you say no to the question on the search form about whether or not you are a current employee, only the jobs open to everyone will be shown in the search results.
Temporary Employment
Every year, the Forest Service hires thousands of temporary employees for a variety of jobs, mostly in the field. The Alaska Region developed a list of temporary positions we expect to fill in 2012. Many of the positions will be filled using open continuous vacancy announcements, which require applicants to choose up to nine duty locations where they are willing to be considered for positions. To assist applicants in choosing the correct location for positions in Alaska, the list provides those duty locations. All positions will be advertised at USAJOBS http://www.usajobs.gov/ and applicants must apply online at AVUE https://www.avuecentral.com/.
