IT Technical Director / System Architect Subject Matter Expert ( with Security Clearance

Quantumn Sky is searching for a IT Technical Director / System Architect Subject Matter Expert (SME) to serve as the principal technical authority, chief engineering strategist, and architecture leader for the Defense Health Agency (DHA) E-Commerce Operational Systems Support (EOSS) contract. In this executive technical capacity, the incumbent oversees the holistic technology vision, architectural governance, cloud modernization roadmap, and cross-functional engineering execution across the entire DHA E-Commerce System (ECS) portfolio.

A primary responsibility is to lead a coordinated automation and DevOps improvement effort across development, infrastructure, database, and cybersecurity teams, reducing manual work, improving release reliability, and establishing repeatable engineering practices. The DHA ECS represents the mission-critical financial, contracting, and operational nerve center supporting the Department of Defense’s multi-billion-dollar TRICARE Private Sector Care (PSC) healthcare program.

Operating within the secure Medical Community of Interest (MedCOI) AWS GovCloud East environment and accessed via the DHA Application Virtualization Hosting Environment (AVHE), the system orchestrates massive, real-time transaction streams across Oracle Federal Financials (OFF R12), the multi-terabyte Enterprise Data Warehouse (EDW), Global Unison PRISM procurement, and direct US Treasury/DFAS financial gateways. The IT Technical Director / System Architect SME bridges strategic DoD mission objectives, enterprise cloud architecture, and tactical software engineering.

This leader chairs the program's Architecture Review Board (ARB), directs technical trade studies, steers major modernization initiatives (including DoD Enterprise ICAM, IPv6 dual-stack conversion, and cloud optimization), and ensures unwavering alignment with Defense Information Systems Agency (DISA) STIGs and DoD Risk Management Framework (RMF) cybersecurity mandates.

• Executive Technical Authority: Serve as the prime contractor’s primary technical spokesperson and authority in technical synchronization meetings with DHA J-8 (Contract Resources Management), DHA DCOPS, and DISA.
• Engineering Roadmap & Modernization Strategy: Formulate, maintain, and execute the multi-year DHA ECS COTS and custom software evolution roadmap identifying end-of-life (EoL) milestones, platform modernizations, and cloud-native adoption opportunities.
• Architecture Review Board (ARB) Governance: Establish and chair the program ARB, reviewing all Engineering Change Proposals (ECPs), Solution Design Documents (SDDs), and major interface modifications prior to Configuration Management Board (CMB) presentation.
• Cross-Workstream Technical Integration: Drive technical coherence across five core program delivery branches: Oracle Federal Financials ERP, Enterprise Data Warehousing/Marts, PRISM Contract Management, Cloud Infrastructure/SysAdmin, and Cybersecurity/ISSO operations.
• Manage Architectural Team: Provide oversight and guidance to a team of 5-7 System Administrators. Ensure milestones, STIGs and patching are kept up to date and compliant.

Enterprise Cloud Architecture & Hosting Governance

• AWS GovCloud Optimization: Architect, scale, and optimize the DHA ECS virtual footprint within MedCOI AWS GovCloud East across multi-tier Development, System Test, QA/Pre-Prod, and Production environments.
• Infrastructure as a Service (IaaS) Liaison: Lead technical coordination with DHA Data Center Operations (DCOPS) and AWS engineering teams regarding compute/storage capacity planning, Application Service Interruptions (ASIs), Change Requests (CRQs), and network routing.
• High Availability & Disaster Recovery: Design and validate the enterprise Continuity of Operations (COOP) architecture, ensuring multi-site data replication, failover execution, and rapid reconstitution to meet strict DoD 99.90% availability targets.
• Virtualization & Remote Access: Oversee system integration with the DHA Application Virtualization Hosting Environment (AVHE/Citrix) and enforce secure admin access protocols via Jumpbox/VDI.

Enterprise Systems Integration & Federal Gateways

• Financial & Claims Architecture: Maintain architectural integrity over custom RICE-W extensions connecting the TRICARE Encounter Data System (TEDS) to Oracle Federal Financials R12 General Ledger, Accounts Payable, and Sub-Ledger Accounting (SLA).
• Federal Treasury Interoperability: Architect automated interfaces and secure communication handshakes for:
• Treasury G-Invoicing: Brokering Intragovernmental Transactions (IGT) Buy/Sell activity for DHA Agency Location Code (ALC) 97000012 under 31 U.S.C. 3512/3513.
• Treasury CARS / CTDE: Daily automated ingestion and reconciliation of Central Accounting Reporting System files against cash disbursements.
• DFAS DDRS & WAWF: Secure transaction delivery via the DoD Global Exchange (GEX).
• PRISM & Clause Logic: Automated commitment/obligation validation handshakes between procurement and accounting engines.
• Data Warehousing & BI Architecture: Guide architectural patterns for Informatica ETL data pipelines, Archive Stage repositories, and Oracle Analytics Server (OAS) / BI Publisher reporting marts (FRDM, ORDM, PRDM, CRDM).

Cybersecurity Architecture, Zero Trust & Compliance

• Security-by-Design Enforcement: Collaborate with the Information System Security Officer (ISSO) and Information System Security Manager (ISSM) to ensure all architectural patterns embed DoD Zero Trust principles and NIST SP 800-53 security controls.
• STIG & Vulnerability Baselines: Direct engineering remediation strategies for DISA Security Technical Implementation Guides (STIGs), Assured Compliance Assessment Solution (ACAS) scans, and Host Based Security System (HBSS) alerts across RHEL, Windows, and Oracle database tiers.
• Identity & Access Management (ICAM): Architect the enterprise transition from legacy authentication to DoD Enterprise ICAM shared services, integrating PKI/CAC/PIV authentication, Non-Person Entity (NPE) certificates, and strict Segregation of Duties (SOD).
• ATO Re-Certification Support: Provide system design artifacts, data flow diagrams, and architectural justifications required to maintain the system's triennial Authority to Operate (ATO).

Quality, Performance & SLA Governance

• Key Performance Indicators (KPIs): Define, benchmark, and report quarterly operational and technical KPIs, analyzing system throughput, batch transaction runtimes, and database latency.
• Critical Incident Resolution: Serve as top-tier technical escalation authority for Sev-1 production outages, enforcing compliance SLAs (e.g., maximum 4-hour recovery window during month-end close and fiscal year-end).
• Technical Standards & SDLC: Enforce modern, IEEE-compliant Software Development Lifecycle (SDLC) best practices, automated code analysis (static/dynamic vulnerability scanning), and Git/GitHub version control workflows.

Automation & DevOps Leadership

• Automation Roadmap & Delivery: Own a prioritized automation backlog and phased DevOps roadmap covering build, test, and deployment pipelines; infrastructure as code and configuration management; database change management; automated security checks; and operational runbooks. Lead implementation within approved hosting, change-control, security, and COTS support constraints.
• Team Adoption & Engineering Standards: Establish shared engineering standards across workstreams, guide implementation and technical reviews, and coach staff in their use. Work with the Program Manager and workstream leads to allocate capacity, assign owners, resolve adoption barriers, and sustain improvement alongside operational commitments. Coordinate required approvals with government stakeholders.
• First 90 Days: Assess manual effort and delivery bottlenecks, establish baseline measures, agree a prioritized roadmap with program leadership, and deliver an initial automation pilot within the first 90 days. Select the pilot within available access and approval constraints and document results and next steps.
• Measurable Outcomes: Track manual effort, change lead time, deployment failure rate, and recovery time. Set improvement targets with program leadership after establishing baselines, and review progress and team adoption regularly.
