About The Position

The Senior Mainframe z/OS Engineer is part of FNTS’s managed services engineering team and is responsible for maintaining customer mainframe environments and resolving technical problems efficiently. The role supports existing mainframe systems, plans and carries out customer system migrations using tape save/restore or software replication, expands customer environments, ensures proper system backup handling, and responds to break/fix issues that threaten system operability or functionality. The engineer works with customers and a multidisciplinary team to migrate environments to FNTS or establish remote management, with minimal impact. The role also supports system and subsystem software releases, maintains golden or sandbox systems, contributes mainframe expertise to infrastructure projects, and helps implement technologies from the team roadmap. Occasional after-hours and weekend support may be needed. The position is expected to be remote from a state listed in the job posting, with occasional travel potentially required for in-person meetings. Work location may change based on business needs.
