Description

Mainframe Setup & Configuration

• Install and tune the z/OS operating system on cloud-hosted or on-premises IBM Z hardware.
• Configure logical partitions (LPARs), I/O subsystems, and network connectivity.
• Define mainframe hardware profiles and allocate resources (CPU, memory, channels).
• Validate system performance benchmarks and readiness for production workloads.

Software Component Implementation 

• Deploy and configure core software for z/OS, z/Linux, and containerized platforms.
• Integrate essential components: monitoring, security, ESM tools, and automation pipelines (e.g., Ansible, STIG enforcement).
• Ensure software configurations meet functionality, performance, and security compliance requirements as defined by the government.

System Software Migration

• Migrate and optimize existing mainframe system software, middleware (e.g., transaction managers, databases), and supporting services to the new hybrid environment.
• Replicate key performance configurations from legacy systems to achieve parity or improvement.

Control Plane Integration 

• Configure and integrate the centralized control plane to support:
  • User authentication and RBAC
  • Resource provisioning
  • Monitoring and alerting
  • Utility-based billing dashboards
• Ensure project performance goals through robust testing and validation.
• Align implementation with DISA’s Statement of Need (SoN) and assist in accreditation processes.

Validation & Performance Tuning

• Conduct system validation, tuning, and benchmarking during initial deployment.
• Monitor system behavior under application load and adjust parameters for throughput and reliability.
• Leverage automation to detect and resolve performance anomalies.

Migration Strategy & Execution 

• Support the automated provisioning and deployment of multiple z/OS and z/Linux instances
• Create and execute workload migration plans, including:
  
  • Application-specific configuration mapping
  • Pre-migration testing and post-migration assessments
• Support disaster recovery planning and backup integration.

Architecture Support

• Provide engineering input to support system design validation, control plane extensibility, and emerging capability integration.
• Recommend infrastructure modifications and ensure implemented systems adhere to DoD hybrid cloud architecture standards.

Requirements

• 8+ years of experience in mainframe systems engineering with expertise in:
• z/OS installation, JES2/JES3, VTAM/TCP-IP
  
  • LPAR and IOCP/HCD configuration
  • Storage and network management (e.g., DFSMS, OSA adapters)
• Proven track record of system software migration, sysplex configuration, and performance tuning.
• Familiarity with Infrastructure and Configuration as Code, STIG compliance, and hybrid/cloud-integrated control planes.
• Understanding of DevSecOps pipelines and application modernization in z/OS or z/Linux.
• Active DoD Secret clearance required.

Preferred Qualifications

• Bachelor's degree
• IAT-II certification (Security+ CE, CySA+, CCNA, GIAC, SSCP)
• IBM certifications in System Z, z/OS Administration, or related domains.
• Scripting proficiency in CLIST or REXX, JCL automation, or experience with z/OSMF.
• Experience with enterprise tools: ServiceNow, Splunk, Tivoli, etc.
• Familiarity with multi-tenant architectures, cloud-integrated IBM Z partitions, and automation frameworks.
