Job Description

General Dynamics is seeking a highly skilled Systems Integration & Production Engineer to join our mission-critical engineering team. In this role, you will bridge the gap between development and production, serving as the primary Subject Matter Expert (SME) for Microsoft Exchange across multiple isolated, high-security networks. You will architect, test, and validate configurations in a dedicated laboratory environment, and directly execute the strategic planning, rollout, and lifecycle maintenance across operational production environments.

This role requires a unique balance of rigorous integration lab testing, high-impact Tier 3 escalation support, and strategic engineering planning. Additionally, you will act as a critical troubleshooting liaison for our enterprise users accessing Department of Defense cloud tenants ( DOD365-Joint and DOD365-SEC ), collaborating directly with external agency technicians to diagnose and isolate complex access issues impacting our workforce. You will also mentor lower-tier administrators to ensure maximum operational uptime.

HOW A SYSTEMS INTEGRATION & PRODUCTION ENGINEER WILL MAKE AN IMPACT:

Duties and Responsibilities

• End-to-End Exchange Architecture: Lead the strategic planning, architectural design, building, and deployment of Microsoft Exchange Server infrastructure in both integration labs and active production environments.

• Tier 3 Escalation Support: Serve as the ultimate escalation point for complex messaging and collaboration failures in production; perform deep-dive root cause analysis on highly classified networks.

• Patch Compliance & IAVA Testing: Conduct Information Assurance Vulnerability Alert (IAVA) testing on Exchange and System Center suites in the lab to validate that security patches do not impede production functionality before deployment.

• Cross-Domain Mail Flow: Maintain, configure, and optimize end-to-end mail flow across separated networks connected via specialized Email Guards; troubleshoot live operational routing anomalies.

• Automation & Monitoring: Write, maintain, and execute advanced automation scripts utilizing standard PowerShell and Exchange management cmdlets to automate production monitoring, health checks, and simulated mail flow.

• Workforce Mentorship & Documentation: Author and maintain comprehensive standard operating procedures (SOPs), deployment guides, and knowledge-base articles; provide technical training and guidance to Tier 1 and Tier 2 system administrators.

• DOD365 & DISA Troubleshooting Liaison: Assist enterprise users with complex DOD365-Joint and DOD365-SEC access issues. Gather technical data and collaborate directly with Defense Information Systems Agency (DISA) technicians to isolate, reproduce, and determine the scope of cloud-tenant anomalies impacting our local workforce (Note: Cloud tenant administration is managed externally).

• Infrastructure Integration: Configure and manage essential infrastructure dependencies required for production Exchange operations, including Active Directory (AD), Public Key Infrastructure (PKI), Group Policies, and Windows Server environments.

WHAT YOU’LL NEED TO SUCCEED:

Basic Qualifications

• Education: Bachelor’s degree in Systems Engineering, Computer Science, Information Technology, or a related field (or equivalent combination of education, technical training, and military/work experience).

• Experience: Minimum of 5–8 years of direct experience with Microsoft Exchange Server engineering, Windows Server administration, and enterprise-level production support.

• Security Clearance: Active Top Secret/SCI security clearance is required.

• U.S. Citizenship: Required due to the nature of the classified work environment.

Required Skills & Technical Competencies

• Enterprise Messaging: Deep technical expertise in Microsoft Exchange Server architecture, database availability groups (DAG), transport pipelines, and client access protocols in large-scale production environments.

• Tier 3 Troubleshooting: Advanced diagnostics capability for complex system integration, identity management, and cross-domain communication failures.

• Directory & Security Infrastructure: Strong proficiency with Active Directory (identity management, schema extensions, replication), PKI (certificate lifecycle, encryption, signing), and Windows Server operating systems.

• Advanced Scripting: Mastery of PowerShell engineering, specifically utilizing Exchange management cmdlets and legacy cmdlets to build test scripts and custom monitoring frameworks.

• Technical Writing: Demonstrated experience creating clear deployment, migration, diagrams, and troubleshooting documentation for down-stream operations teams.

• Cloud-Liaison Capabilities: Strong analytical skills to diagnose client-side connectivity or authentication issues with Microsoft 365 / DOD365 enclaves, coupled with the ability to clearly articulate technical symptoms to external DISA support teams.

Preferred Certifications & Experience

• Advanced Exchange Engineering: Proven track record of executing full-lifecycle Microsoft Exchange upgrades, schema updates, migrations, and complex disaster recovery procedures.

• Messaging Certifications: Legacy Microsoft Certified Solutions Expert (MCSE): Productivity (Messaging focus) or equivalent modern role-based Microsoft Exchange specializations.

• Performance Tuning: Direct experience with database health management, optimization of index structures, storage allocation, and transaction log troubleshooting for high-availability Exchange environments.

• Advanced Transport & Hygiene: Deep familiarity with Exchange transport rule architecture, message tracking logs, and deep packet evaluation of SMTP mail flow.

• DoD Baseline Compliance: DoD 8570 IAT Level II baseline certification (e.g., Security+ CE, CySA+, or higher).
