Personnel Force Innovation (PFI) Program
Let all your professional acquaintances know you are looking for a tour. You may hear about a tour through a friend of a friend of a friend.
Employer Partnership of the Armed Forces www.employerpartnership.org This website was established and is maintained by Office of the Chief, Army Reserve, but can be used by Reservists from any branch of the service, as well as Veterans and Retirees. These employers are committed to hiring Reservists. They know you are a Reservist and they are committed to accommodating your military career.
USAJOBS: www.usajobs.opm.gov This is the main federal civilian job bank. There are many, many wanna-be and copy-cat websites that merely lead you right back to USAJOBS or just copy-paste text from USAJOBS.
Civilian Expeditionary Workforce (CEW)
CEW generally takes people who are already in the federal civil service system. However, they do accept people who are not civil servants. You get made a temporary civil servant for the length of the tour. This is NOT a backdoor into the civil service system. To repeat, if you get picked up by CEW, you become a temporary civil servant only for the length of the tour.
All the services are supposed to list all their jobs on USAJOBS. Sometimes they do, sometimes they don’t. Check the services’ websites in addition to the USAJOBS website. Also, each service has its own application format. You need to create your resume/application at the USAJOBS website plus at all of the services’ websites.
