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 life cycles – 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 Power Shell) 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 work streams.
• Deliver consistently under time-sensitive conditions and provide executive-ready briefings, updates, and status reports.
