The Opportunity

Are you interested in continuing your career in Europe in a mission focused environment? CACI has established and upcoming positions throughout the European theater supporting multiple customers for the Department of Defense. We are looking for experienced, innovative and motivated IT Specialists to support enablement US EUCOM's mission objectives.

As a Senior Systems Engineer on our Platforms team, you will play a crucial role in managing and maintaining our enterprise Windows environment. A significant part of your role will include reviewing, cleaning up, and streamlining our comprehensive Group Policy Objects (GPOs) to ensure optimal performance and manageability. Additionally, you will help establish and enforce policies, processes, and documentation standards to improve our operational efficiency and effectiveness. This includes implementing Markdown-based guides for server deployment, STIG remediation, GPO cleanup, and script version controlling. Your expertise will ensure the reliability, security, and efficiency of our Windows environment and automation systems.

Responsibilities

• Engineering & Operations: Plan, execute, and sustain complex infrastructure work across Active Directory, Group Policy, DNS/DHCP, PKI/Certificate Services, MECM, and SCOM. This includes platform upgrades, architecture changes, OS migrations (Windows 11, RHEL 10, Server 2025), break-fix resolution for multi-system issues, and day-to-day operational sustainment. This is the primary function of the role.
• Active Directory Management: Administer, manage, and support Active Directory services including user accounts, group policies, security configurations, privileged account lifecycle, ADFS, and trust relationships.
• Windows Server Administration: Install, configure, and maintain Windows Server environments, ensuring optimal performance, reliability, and STIG compliance across multiple sites.
• GPO Cleanup and Optimization: Review, clean up, and streamline existing Group Policy Objects to improve system performance and manageability. Implement AGPM-based governance with Git-backed version control and approval workflows.
• PKI and Certificate Services: Support and maintain the enterprise PKI hierarchy including Intermediate CA operations, CRL lifecycle management, and OCSP configuration.
• GitLab CI/CD and Automation: Design, implement, and manage CI/CD pipelines and infrastructure-as-code workflows using GitLab. Maintain version-controlled documentation and merge-request-based change governance.
• System Security: Ensure the security of Windows platforms through STIG remediation, patch management, ACAS vulnerability remediation, and alignment with DISA security baselines and CCRI readiness criteria.
• Documentation and Change Governance: Produce Engineering Implementation Plans (EIPs), Engineering Design Plans (EDPs), or equivalent technical writeups in Markdown for all major changes and break-fix actions. Documentation must capture rationale, decisions made, and replication steps, submitted through GitLab for peer review.
• Mentorship and Knowledge Transfer: Mentor junior and mid-level administrators through structured project pairing on real production work, over-the-shoulder training, and creation of reusable runbooks. Contribute to weekly Learn-Friday sessions and brown bags by presenting completed work, lessons learned, and technical deep dives.
• Cross-Functional Awareness: Maintain working familiarity with adjacent team workstreams including CyberArk PAM, MECM/SCUP/App-V endpoint management, and Red Hat Enterprise Linux operations. Coordinate effectively with dedicated engineers in those areas.
• Collaboration: Work closely with cybersecurity, networking, architecture, and project management teams to ensure seamless integration and operation of systems and services.
• Process Improvement: Establish and enforce policies and processes to improve operational efficiency, reduce configuration drift, and standardize how the team delivers and documents engineering work.
• Monitoring and Troubleshooting: Proactively monitor system performance using SCOM, Splunk, or equivalent tooling. Identify issues, perform root cause analysis, and document resolution for institutional knowledge.

The successful candidate must communicate clearly and succinctly both written and orally, and present technical concepts and recommendations in a professional manner. This role operates in a dynamic, fast-paced environment that requires team coordination, independent judgment, and the ability to context-switch between project deliverables, operational sustainment, and unplanned incidents. The Senior Platforms Engineer is expected to be self-directing on assigned work. The Platforms Lead provides scope, priority, and architectural direction, but does not direct step-by-step execution. You are trusted to own your work end-to-end: plan it, execute it, document it, and make sure someone else on the team can learn from it.
