IBM z/OS - Z Systems Engineer (Main
Washington, DC (remote) MUST: Experienced IBM Z Systems Engineer Secret clearance required 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. 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. DUTIES: Seeking a highly experienced IBM Z Systems Engineer to support the modernization of the mainframe environments through a mainframe hybrid cloud prototype. This role will perform the implementation of z/OS, Linux on Z, and container-based systems within a modernized on-premises infrastructure that integrates with centralized control planes, automation platforms, and multi-cloud resources. The engineer will ensure operational continuity, performance parity, and security compliance during system setup, software integration, and workload migration. Job Duties and Responsibilities: 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. Quadrant is an affirmative action/equal opportunity employer.
