The U.S. National Park Service's website is a gateway to jobs for high school, college and graduate school students who want to work within one of the nation's parks or in another area of the organization. The NPS has partnered with the Geological Society of America and the Student Conservation Association, among other organizations, to offer both seasonal and year-round internships. Internships are also offered by the U.S. Fish and Wildlife Service.
Other federal agencies that provide environmental job postings are the U.S. Geological Survey and the U.S. Forest Service. Opportunities within the USGS and the U.S. Forest Service can be accessed from the jobs databases located on the U.S. Office of Personnel Management's USAJOBS website.
Some nonprofit and nongovernmental organizations with websites that have environmental job postings are the National Audubon Society, the National Wildlife Federation, the National Recreation and Parks Association and the Sierra Club. Private sector firms such as Golder Associates, a global consulting firm that focuses on the earth, environment and energy sectors, also have sections on their websites dedicated to positions they are looking to fill.
For postdoctoral research positions, the National Exposure Research Laboratory of the U.S. Environmental Protection Agency provides a list of vacancies on its website.
