iAgami Technologies - Mainframe Modernization Solution Architect

Description :

The Mainframe Migration to Cloud Solution Architect is responsible for defining the technical strategy, architecture, and blueprints for migrating and modernizing complex mainframe applications and data to a target public cloud platform (e.g., AWS, Azure, GCP).

This role ensures the resulting solution is secure, scalable, cost-optimized, and aligned with the client's business Responsibilities and Strategy Definition :

• Lead the comprehensive discovery and assessment of existing mainframe applications, data stores (DB2, VSAM, IMS), batch processes (JCL), and transaction systems (CICS, IMS DC).
• Analyze application dependencies, complexity, and business criticality to determine the most suitable modernization strategy for each component (e.g., Rehost, Replatform, Refactor, Retire, or Replace the "6 Rs").
• Develop the overall migration roadmap and high-level project phasing, including business continuity and rollback and Design :
• Define the target-state cloud architecture for the modernized applications, leveraging cloud-native services (e.g., Containers / Kubernetes, Serverless, Managed Databases).
• Create detailed architecture blueprints for all migration patterns, ensuring the design meets non-functional requirements (security, performance, high availability, disaster recovery).
• Design the data migration strategy, including tools and processes for extracting, transforming, and loading (ETL) mainframe data to modern cloud databases (e.g., Aurora, Azure SQL, Cloud Spanner).
• Design API gateways and microservices wrappers to decouple core mainframe business logic from modern front-end systems during hybrid migration and Governance :
• Evaluate and select mainframe modernization tools and frameworks (e.g., Micro Focus, Blu Age, AWS Mainframe Modernization, IBM Z systems tools) for automated code and data conversion.
• Establish DevOps and CI / CD pipelines for the modernized environment, enabling automated build, test, and deployment of cloud-native code.
• Define cloud governance and cost optimization frameworks, ensuring efficient use of cloud resources and Stakeholder Management :
• Serve as the technical subject matter expert (SME), presenting the solution architecture to client executives, development teams, and operations teams.
• Collaborate with business analysts to translate functional and non-functional requirements into technical designs.
• Lead and mentor technical teams (developers, engineers) during Proof of Concepts (POCs) and initial implementation Technical Skills and Qualifications Expertise (Deep Knowledge) & Components :
• COBOL, PL / I, Assembler, JCL, & Files :
• DB2 for z / OS, VSAM, IMS Systems :
• CICS, :
• TSO / ISPF, SPUFI, mainframe schedulers (CA-7, & Modernization Expertise (Expert Level) :
