• Troubleshoot system and network problems, diagnosing and solving hardware or software faults
• Replace parts as required
• Provide support, including procedural documentation and relevant reports
• Follow diagrams and written instructions to repair a fault or set up a system
• Support the roll-out of new applications
• Set up new users' accounts and profiles and deal with password issues
• Work continuously on a task until completion (or referral to third parties, if appropriate)
• Prioritize and manage many open cases at one time
• Rapidly establish a good working relationship with customers and other professionals, such as software developers
• Test and evaluate new technology
