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.

- 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).
