About the project

Responsibilities

• Optimize System Control → Ensure the stable operation of central systems (z/OS), subsystems, and server infrastructures (Linux, Unix, Windows), using Grafana, Prometheus, OpenSearch, and automated CLI scripts for monitoring, log analysis, and secrets/certificates management.

• Streamline Event Management → Manage event processing end-to-end, coordinating deployments and handling application-specific configuration updates to ensure smooth, interruption-free operations.
• Resolve Complex Issues → Take ownership of escalated 2nd/3rd-level issues—ranging from certificate management and memory leaks to database and firewall connectivity problems—restoring system stability efficiently.
• Strengthen Incident Recovery → Lead incident recovery efforts by ensuring rapid service restoration, structured deployment execution, and clear, consistent operational documentation.
• Implement Process Improvements → Drive continuous improvement by implementing standardized changes, supporting emergency drills, collaborating with internal client teams, and optimizing CI/CD processes.

Qualifications

Must have:

• Vocational training in IT, a degree in computer science, or equivalent professional experience.
• Solid knowledge of operating systems such as z/OS, Linux, and Windows, including operational control and administration.
• Practical experience with scripting languages such as PowerShell and Python.

• Emotional Wellbeing: We believe that to maintain our overall health, we need to invest in our mental wellbeing just as much as we do in our physical health, social connections or in achieving work-life balance.
• Social Wellbeing: As a growing community in a hybrid environment, we want to ensure we remain connected not just by the great work we do every day but through our passions and interests.
