• Participate in escalated ticket triages and ensure timely resolution.
• Develop and maintain scripts to automate repetitive tasks and prevent recurring escalations.
• Conduct detailed incident analysis and provide comprehensive reporting to the business.
• Perform root cause analysis for incidents and liaise with third-party providers such as Microsoft Premier when necessary.
• Draft infrastructure architecture documentation and store it in the corporate knowledge library.
• Create solution documents for delegation to 1st and 2nd line support, reducing unnecessary escalations.
• Focus on continuous improvement of infrastructure processes and performance.

• Experience with Exchange in a hybrid setup (preferred).
• Experience with Microsoft 365 services such as Teams and OneDrive (preferred).
• Knowledge of DevOps practices and their application to infrastructure engineering.
• Experience working with ticketing systems, preferably ManageEngine.
• A proactive approach to staying up to date with emerging technology trends.
