Job Description:

Shape the Mission. Engineer the Future.

GDIT is your place to lead, innovate, and drive strategic change. We are seeking a Senior System Administrator / Integrator with proven experience delivering mission-critical integration for complex, multi-domain DoD environments. In this role, you'll be at the forefront of geospatial and intelligence system evolution — leading integration efforts, shaping architectural solutions, and mentoring technical teams.

As a Senior System Administrator / Integrator, you will lead the design and integration of advanced geospatial and intelligence platforms. Your work will translate operational and technical requirements into secure, scalable, and forward-looking architectures that align with Army modernization and convergence efforts.

What You’ll Do:

• Guide integration strategies across multi-vendor software stacks and hardware baselines.
• Engage directly with Army stakeholders to refine system requirements, track dependencies, and drive alignment across multiple Army government organizations.
• Provide technical leadership across full system lifecycles — from concept to operational deployment — ensuring rigorous engineering discipline and mission continuity.
• Develop integration test strategies, manage system validation efforts, and oversee performance tuning and issue resolution for both imagery and geospatial software baselines.
• Lead integration efforts and manage complex issues in real-time and driving improvements for interoperability and readiness.

Key Responsibilities:

• Serve as technical lead for Army systems integration initiatives and geospatial software baselines.
• Develop system-level architecture views, data flow diagrams, and interface designs.
• Lead the generation of integration artifacts including test plans, conformance matrices, and cross-domain interface documentation.
• Interface with senior DoD stakeholders to provide updates, recommendations, and roadmap alignment.
• Provide expertise in Army’s Gold Master baselines and guide transition planning for new software versions.
• Apply advanced scripting and automation (especially PowerShell) to streamline integration, testing, and configuration management.
• Contribute to high-level technical decision-making with the mindset of “trust but verify,” driving standards across engineering teams and integration workstreams.
• Deliver consistently under time-sensitive conditions and provide executive-ready briefings, updates, and status reports.

Required Skills & Qualifications:

• DoD Cyber Workforce Framework (DCWF) 8140
  • IAT Level II: CompTIA Security+, CySA+, or GSEC
• Hands-on expertise with ArcGIS Enterprise, ArcGIS Desktop, and supporting geospatial toolkits.
• Experience integrating with Army tactical systems and understanding of Geospatial Engineer (12Y) workflows across Army echelons.
• Familiarity with Army organizational constructs, GPC operations, and MIB-T system support environments.
• Knowledge of secure DevSecOps principles and CI/CD pipelines supporting rapid capability deployment.

Advanced PowerShell Skills:

• Proficient in developing robust, production-level scripts featuring:

• Data types and keywords.
• Logic constructs.
• Functions and modules.
• Data pipeline and parameter binding.
• Text processing and regular expressions.
• Cmdlets and modules.
• External process invocation with output redirection and error checking.
• Data file reading/write/manipulation (xml, json).
• Concurrent processing using powershell jobs or runspace pools.
• Code debugging.
• Advanced data handling (XML/JSON).
• REST API interaction.
• Parallel processing via runspaces.
• Secure credential handling and error management.
• Modular, reusable architecture.
• Custom logging and diagnostic utilities.
• Experience integrating PowerShell with system and application layers for real-time diagnostics, patch automation, and configuration baselining.
