Charlestown has posted the application for the acting Town Administrator position on the town website. Applicants need not be a resident of the town.
There is a quick deadline on this; applications must be received by noon on Tuesday, February 7, because the Town Council is scheduled to review applications at a Council meeting on Tuesday. At that meeting they expect to select one or more applicants for interviews in Executive Session on Thursday, February 9.
Note that applications will be public information.
