• Strong skills in service outage management, with the ability to drive major incidents to resolution end-to-end while keeping end users informed and supported throughout
• Sound knowledge of Active Directory and Azure Active Directory (Entra ID), including how identity, authentication, and hybrid sync flow across the environment
• Solid understanding of networking fundamentals (DNS, DHCP, TCP/IP) and Windows Server/OS concepts as they relate to messaging and collaboration workloads
• Practical PowerShell scripting skills for day-to-day administration, bulk operations, diagnostics, and automating repetitive tasks
• Working knowledge of hybrid Exchange environments, including AD Connect/Entra Connect sync health and troubleshooting
• Familiarity with mail security and compliance tooling (e.g., Microsoft Defender for Office 365, Microsoft Purview, Mimecast) for spam, phishing, and data protection scenarios

• Provides input into environment design, configuration standards, and long-term improvements based on recurring issue patterns and root cause trends
• Working knowledge of SharePoint Online (SPO) as an add-on skill — covering site/permission management, common sync and access issues, and how it integrates with OneDrive and Teams

Management Skills:

• Excellent analytical skills paired with expert-level documentation — able to turn complex technical issues into clear, reusable knowledge for the wider team
• Hands-on experience managing the full ITSM lifecycle — Incidents (INC), Service Requests (SR), and Problem Records (PRB)- from logging through to resolution and closure
• Practical experience raising and managing Change Requests (CR), including presenting at CAB (Change Advisory Board) and adhering to approved implementation schedules
• Strong adherence to defined SLAs, change windows, and implementation timelines, with a track record of minimal deviation
• Sound knowledge of the ITIL framework and how it is applied day to day across Incident, Problem and Change Management

• Reporting-oriented — able to translate operational data into insights that inform leadership and drive continuous improvement

Process Skills:

• Excellent verbal and written communication skills
• A genuine team player who fosters collaboration and inter-group coordination rather than working in silos
• Fast learner with a proven track record of picking up new technologies quickly and applying them with operational excellence
• Curious and forward-looking — actively explores AI adoption and emerging tools to improve how support is delivered, not just how it's documented
• Demonstrated history of continuous learning, upskilling, and delivering measurable achievements in past roles
