Responsibilities

Peraton's 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.

Peraton is seeking a Senior GIS Developer to lead the production of federal species range maps for a high-priority data integration program. You will produce range maps for marine and anadromous taxa in compliance with the U.S. Fish and Wildlife Service (FWS) Range Mapping Standard Operating Procedure (SOP), facilitating iterative review cycles with government SMEs and coordinating formal government sign-off.

Work Location: Remote

Day to Day Responsibilities:

• Lead species range map production, producing complete range maps for all marine and anadromous taxa in full compliance with the FWS Range Mapping Standard Operating Procedure (SOP)
• Obtain and review the FWS Range Mapping SOP at or before project kickoff
• Conduct spatial data aggregation and normalization of range data from cloud data platform outputs, applying CRS transformations and spatial format standardization
• Validate spatial intersects against authoritative geographic layers, addressing dynamic habitat boundaries and overlapping Critical Habitat designations
• Facilitate iterative range map review cycles with both FWS Ecological Services and NOAA Fisheries (National Marine Fisheries Service) SMEs, incorporating feedback and producing revised map versions
• Produce QA documentation for each individual range map, ensuring all maps meet SOP acceptance criteria before submission for government sign-off
• Coordinate FWS Ecological Services sign-off on the Range Map Set deliverable
• Support the development of updated range maps post-production as part of operational handoff documentation
