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: Architecture Assessment & Modernization PlanningLead 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. Solution Design & IntegrationArchitect modern hybrid cloud solutions that integrate mainframes with platforms like AWS GovCloud or Azure IL5.Define architectures that support:API enablement for legacy systemsReal-time data exchange and data lakesInfrastructure-as-Code deploymentsAI/ML pipelinesAlign all solutions with the DoD Data Strategy, VAULTIS principles, and Zero Trust mandates. Technical OversightLead 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. Compliance and Governance AlignmentApply 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 modernizationMainframe-to-cloud transitions (IBM Z to AWS, Azure)Hybrid cloud and edge integrationMetadata-driven data architecture, DataOps, and decoupled compute/storeStrong experience with modernization toolsFamiliarity with architecture modeling frameworksPreferred Certifications:AWS, Azure, or Google Cloud Architect CertificationSAFe Architect or Agile Architecture-related certificationOriginally posted on Himalayas
