  • Collaborate with Linux admins and application teams to troubleshoot interactions between database, application, and OS layers.
  • Execute weekend changes and perform database operations during controlled maintenance windows, including pre- and post-change validations.

  • Experience with IBM Sterling File Gateway, IBM Connect:Direct, or BMC Control-M.
  • Exposure to financial services or regulated environments.
  • Supporting batch/file transfer platforms.
