Scripting and Automation: Basic scripting knowledge (PowerShell, Bash, Python) for automating routine tasks and troubleshooting complex issues.

Advanced Troubleshooting and Problem Solving

Log Analysis: Reading and interpreting system and network logs to diagnose and resolve technical issues.
System Performance Tuning: Diagnosing performance bottlenecks in hardware, applications, and networks, and suggesting improvements.
Incident Management: Following standard ITIL (Information Technology Infrastructure Library) practices for incident escalation, documentation, and resolution.

Collaboration: Working effectively with Level 1 (frontline) support teams, and escalating issues to Level 3 or specialized support teams when necessary.
Documentation: Creating and updating technical documentation, including knowledge base articles and standard operating procedures (SOPs).
Ticket Management: Using ticketing systems (e.g., Jira, ServiceNow, Zendesk) to manage and resolve technical support requests.

Endpoint Security: Ensuring that workstations, laptops, and mobile devices are secured against potential threats.
Backup and Disaster Recovery: Familiarity with backup solutions, disaster recovery planning, and ensuring data integrity.

Database Management

Basic SQL Knowledge: Understanding of databases and SQL queries for troubleshooting database-related issues or working with database administrators (DBAs).
Backup and Restore: Ability to perform basic database backups and restore operations in case of failure.

Project Support

Support for IT Projects: Participating in IT projects such as software rollouts, infrastructure upgrades, or migrations.
Change Management: Understanding change control processes and ensuring that system changes are well-documented and implemented according to organizational policies.

Remote Support Tools

Remote Troubleshooting: Proficiency with tools like TeamViewer, AnyDesk, or Remote Desktop Protocol (RDP) for assisting users remotely.
Monitoring Tools: Familiarity with network and system monitoring tools (e.g., Nagios, SolarWinds, PRTG) to proactively identify issues.

Time Management and Prioritization

Task Prioritization: Ability to prioritize tasks based on the severity and impact of technical issues.
Multitasking: Managing multiple incidents or service requests at the same time while ensuring timely resolution.

Vendor and Third-Party Support

Vendor Management: Liaising with third-party vendors for escalated technical issues related to specific hardware or software products.
Warranty and RMA (Return Merchandise Authorization) Management: Handling warranty claims and equipment replacements through vendor support.

Certifications:

Essential

Microsoft Certifications: (e.g., Microsoft Certified: Azure Administrator, Microsoft 365 Certified).
ITIL Foundation V4: For understanding IT service management (ITSM) processes.

Optional but Beneficial
