- Configure, maintain and troubleshoot federated ArcGIS Enterprise systems in DDIL environments, including support for replication, synchronization, and bandwidth-limited operations.
- Develop geospatial automation tools and workflows using Python, including the ArcGIS API for Python, geoprocessing scripts, and other Python libraries as necessary.
- Implement and maintain secure, multi-enclave environments and cross-domain GIS data flow.
- Assist with creating interactive spatial products using ArcGIS Enterprise applications such as ArcGIS Dashboards, Experience Builder, and StoryMaps.
- Collaborate with sysadmins, developers, and mission analysts to integrate GIS services with other enterprise applications and interfaces.
- Author detailed technical documentation, configuration baselines, and SOPs in compliance with DoD and NIST guidelines.
Required Qualifications:- U.S. Citizenship and active DoD Secret clearance with ability to obtain and maintain TS/SCI.
- 5+ years of hands-on experience deploying and managing ArcGIS Enterprise (10.9.1 or newer).

- Experience deploying ArcGIS Enterprise solutions in virtual environments.
- Deep understanding of federated server configurations and enclave-separated GIS systems.
- Python scripting skills, especially with the ArcGIS API for Python.
- Experience working in DDIL or disconnected tactical environments, (e.g., offline data, map caches).
- Familiarity with secure DoD infrastructure and cross-domain deployment patterns.
- Minimum of IAT II Certifications to meet DoD 8140 compliance: CompTIA Security+ (or equivalent) and training or vendor certifications in Windows, Linux, VMWare, Cisco (CCNP/CCNA).
- GISP (Certified GIS Professional) certification.
Preferred Qualifications:- Understanding of PostgreSQL/PostGIS, SQL Server, and other enterprise database platform integration.
- Experience developing with ArcGIS Enterprise application capabilities (ArcGIS Experience Builder, ArcGIS Dashboards, and ArcGIS StoryMaps) to add mission-focused value.
- Experience configuring tools for monitoring system performance and availability.
- Familiarity with DevSecOps practices, including containerization (e.g., Docker, Kubernetes), CI/CD pipelines, and Infrastructure-as-Code tools (e.g., Terraform, Ansible).
- Familiarity with network concepts and topics, such as domains, directories, DNS, HTTPS, firewalls, proxies, load-balancing.
- Familiarity with authentication concepts and topics (e.g., SAML).
