- Support & Incident Response: Serve as an escalation point for infrastructure-related requests, guiding and mentoring IT Support colleagues.
- Tooling & Enterprise Platforms: Help to administer M365, Atlassian, GitHub, and other enterprise systems.
- Governance and Compliance: Ensure systems are fully documented, risk assessed, and all relevant assurance testing is completed correctly.
