The U.S. Fish and Wildlife Service (USFWS) is the premier federal agency charged with protecting and enhancing America's treasured fish, wildlife, plants, and their habitats.

We are seeking a Senior Java Engineer to help support the efforts of the USFWS.  Our team is the steward of two exceptional software products: public facing IPaC (Information Planning, and Consultation); and internally facing EPM (Effect Pathways Manager), which helps biologists break down the effects of industry activities on threatened and endangered species. Both products continue to enjoy high demand and funding for development of new features.

Work on the IPaC team has a fast impact on the success of the USFWS products. This work directly correlates with the success of natural resources conservation and we see the product of our time, energy, and creativity making a difference.
