  • Ensure the stability, availability, and performance of Mainframe applications.
  • Apply security best practices in the Mainframe environment.
  • Develop scripts and automation to optimize processes and repetitive tasks.
  • Collaborate with cross-functional teams and business areas to analyze and implement solutions.
