Mainframe Infrastructure Engineer (Hybrid Role)

Who We Are At Kyndryl, we design, build, manage and modernize the mission-critical technology systems that the world depends on every day. So why work at Kyndryl? We are always moving forward – always pushing ourselves to go further in our efforts to build a more equitable, inclusive world for our employees, our customers and our communities. The Role Mainframe Infrastructure Engineers at Kyndryl are project-based subject matter experts in all things infrastructure – good at providing analysis, documenting and diagraming work for hand-off, offering timely solutions, and generally “figuring it out.” This is a hands-on role where your feel for the interaction between a system and its environment will be invaluable to every one of your clients. * This role requires employees to live in or around the Phoenix, AZ area. You will be responsible to be onsite 3 days a week. We will consider candidates who are willing to relocate to the area. Responsibilities Platform & Infrastructure Operations Operate, maintain, and optimize z/OS LPARs, Sysplex, WLM, JES2/JES3, USS/OMVS, TSO/ISPF, SDSF. Install, configure, and maintain mainframe software using SMP/E and vendor best practices. Monitor and tune system performance using RMF, SMF, OMEGAMON (or equivalent), addressing CPU, memory, I/O, and throughput. Subsystem & Product Support (MF Application-Adjacent) Support and administer DB2 for z/OS, CICS TS, IMS (DB/TM) , and IBM MQ: configuration, health checks, upgrades/maintenance, performance tuning, and high availability. Work with application teams for deployment validation, capacity estimates, SQL/CICS/IMS tuning, MQ channel/queue configuration, and resolving production incidents. Production Control & Scheduling Manage workload automation and batch scheduling with tools such as Control‑M, CA‑7, ESP/Autosys, or equivalent; ensure batch SLAs and critical path adherence. Troubleshoot JCL, dataset management, procs, condition codes, and abends; perform restart/recovery and reruns. Improve job streams for efficiency and reliability (dependency modeling, calendars, alerts, event-driven triggers). Storage Management Administer DFSMS (ACS routines, storage groups/classes), DFSMShsm (HSM policies, space management, migration/recall), and Catalog/ICF management (IDCAMS). Manage DASD and tape subsystems (e.g., DS8000, TS7700), volumes, VTOCs, data sets, and replication. Partner with backup/recovery teams on policy, FlashCopy/Snap, DR readiness, and test execution. Reliability, Security & Compliance Implement and maintain RACF/ACF2/Top Secret security controls; support audits and compliance (SOX, PCI, ISO, etc.). Participate in BCP/DR planning, testing, and documentation. Apply SRE/operational excellence practices: error budgets, toil reduction, problem elimination, and automation-first mindset. ITSM & Change Management Drive incident, problem, and change processes (e.g., in ServiceNow): root cause analysis, post-incident reviews, and controlled deployments. Author and maintain runbooks, SOPs, architecture diagrams, and knowledge articles. Your future at Kyndryl There are lots of opportunities to gain certification and qualifications on the job, and you’ll continuously grow Many of our Mainframe Infrastructure Engineers are on a path toward becoming either an Architect or Distinguished Engineer, and there are opportunities at every skill level to grow in either of these directions.

Practical experience with at least two of: DB2, CICS, IMS, IBM MQ (configuration, troubleshooting, performance). Production control experience with Control‑M, CA‑7, ESP/Autosys, or equivalent; deep JCL and batch troubleshooting skills. Storage fundamentals: DFSMS, DFSMShsm, ICF catalog/IDCAMS, DASD/tape operations, space/VTOC management. Proficiency with monitoring and performance analysis (RMF/SMF, OMEGAMON, or similar). Familiarity with RACF/ACF2/Top Secret concepts, access models, and audit support. Solid understanding of ITIL processes and experience using an ITSM tool (preferably ServiceNow) for incident/problem/change. Strong analytical, communication, and stakeholder management skills; ability to work in a follow‑the‑sun/on‑call support model. Preferred Qualifications Experience with Parallel Sysplex, GDPS, XCF, and high-availability designs. Advanced tuning skills for DB2 buffer pools, CICS regions, IMS databases, MQ channels/queues. Exposure to z/OSMF, Ansible for z/OS, Zowe, or API-driven automation. Knowledge of networking on z/OS (TCP/IP stacks, VTAM/SNA, Enterprise Extender). Scripting/programming: REXX, Assembler basics, COBOL reading, Python on USS. Experience with capacity planning and cost optimization (MSUs, WLM policies). Background in regulated/enterprise environments (financial services, government, healthcare, retail). Technologies (Representative) OS & Core : z/OS, JES2/JES3, WLM, USS, TSO/ISPF, SDSF, SMP/E, IPCS Subsystems : DB2 for z/OS, CICS TS, IMS
