Solution Architect–Legacy System Modernization
Job Summary:
The Solution Architect is the technical lead responsible for assessing legacy systems, designing secure and scalable modernization strategies, and guiding the architectural transformation of mission-critical applications, infrastructure, and data systems. This role drives technical decision-making across assessment and implementation task areas, ensuring that all solutions align with customer mission objectives, DoD compliance requirements, and emerging technology best practices.
Job Duties and Responsibilities:
- Lead assessments of legacy systems including COBOL-based applications, IDMS/IMS databases, and monolithic workflows.
- Analyze technical debt, data flows, interface complexity, and code maintainability to define modernization paths (refactor, replatform, replace).
- Collaborate with PMO and mission partners to develop actionable modernization roadmaps.
- Architect modern hybrid cloud solutions that integrate mainframes with platforms like AWS GovCloud or Azure IL5.
- Define architectures that support:
- API enablement for legacy systems
- Real-time data exchange and data lakes
- Infrastructure-as-Code deployments
- AI/ML pipelines
- Align all solutions with the DoD Data Strategy, VAULTIS principles, and Zero Trust mandates.
- Lead the design of modernization artifacts such as architecture blueprints, sequence diagrams, security models, and deployment workflows.
- Direct the implementation of DevSecOps pipelines, automated testing suites, and container orchestration (e.g., Kubernetes/OpenShift).
- Ensure technical alignment between development, security, data, and infrastructure teams.
- Apply DoDAF and enterprise architecture methodologies to guide system alignment with mission goals.
- Ensure all architectures meet DISA STIGs, NIST 800-53, RMF, and CPTC security mandates.
Job Requirements (Education/Skills/Experience):
Required Skills & Experience:
- Active Secret clearance required.
- 10+ years of experience in solution or enterprise architecture for large-scale federal systems.
- Expertise in:
- Legacy system assessment and modernization
- Mainframe-to-cloud transitions (IBM Z to AWS, Azure)
- Hybrid cloud and edge integration
- Metadata-driven data architecture, DataOps, and decoupled compute/store
- Strong experience with modernization tools
- Familiarity with architecture modeling frameworks
Preferred Certifications:
- AWS, Azure, or Google Cloud Architect Certification
- SAFe Architect or Agile Architecture-related certification
