Peraton is seeking a Senior Web Developer (UI & API Integration) to lead front-end development and API integration for a federal environmental platform. You will design and implement user interface updates that enable federal users to access new species data for regulatory consultations, ensuring full Section 508 accessibility compliance throughout. This is a fully remote position.

The Department of the Interior (DOI), U.S. Fish and Wildlife Service (FWS), and NOAA's National Marine Fisheries Service (NMFS) have identified a critical gap in the federal government's ability to conduct comprehensive Endangered Species Act (ESA) research. While FWS operates an authoritative web-based platform for managing data for terrestrial and freshwater species, it does not currently include NMFS marine and anadromous species data forcing agencies to rely on separate, manual processes. This program closes that gap by integrating marine and anadromous species data into the existing FWS platform, creating a single, unified experience for all ESA-listed species.
