Description An Azure Architect with Mainframe and TPF (Transaction Processing Facility) experience designs and leads the migration, modernization, and optimization of legacy mainframe systems-particularly high-performance IBM z/TPF environments used in transaction-heavy industries like airlines or finance-to Client Azure cloud infrastructure.

Key Responsibilities

• Architect cloud-native solutions for refactoring z/TPF workloads, including re-platforming online transaction processing (OLTP) apps to Azure services like Azure Kubernetes Service (AKS), Cosmos DB for NoSQL data, and Virtual Machine Scale Sets for scalability.
• Define migration strategies, such as lift-and-shift with Azure Site Recovery or full refactoring to microservices, while ensuring low-latency performance equivalent to TPF's shared-memory coupling and partition isolation.
• Implement CI/CD pipelines using Azure DevOps, integrate security via Azure Active Directory (AAD), RBAC, and monitoring with Azure Monitor for mainframe-like reliability.

Required Skills

• Deep expertise in Azure PaaS/IaaS (e.g., AKS, App Services, Blob Storage) and mainframe technologies like TPF Assembly, C++, TN3270/HTTP protocols, and middleware for queuing/output.
• Experience with application modernization tools (e.g., Azure Database Migration Service), data refactoring to Cosmos DB, and handling high-throughput transactions.
• Proficiency in infrastructure automation (Terraform, ARM templates), security governance, and hybrid setups comparing Azure vs. on-prem mainframes.

Typical Qualifications

• 8+ years in cloud architecture, with 3-5 years specifically in mainframe modernization (z/TPF to Azure) and full-stack development (e.g., Java, Python for microservices).
• Certifications like Client Certified: Azure Solutions Architect Expert; bonus for mainframe-specific knowledge (AS/400, DB2).
• Strong problem-solving for performance, HA/DR, and cost optimization in enterprise migrations.
