- Prepare CHG packs; support implementation (configuration execution, ZTP/CVP, cutover tests).
- Ensure step, rollback and test plans are agreed and followed.
- Coordinate the 4‑eyes implementation plan and approval evidence.
- Finalise closure: handover, documentation and lessons learned.
Security Connectivity Engineering (ACR / Firewall / Subnets)
- Build the user subnet inventory using Netbase (source of truth).
- Run Eagle Eye reports (src/dst, last‑used timestamps, ports/applications).
- Present results to ITAOs and support iterative analysis.
- Maintain the Rules to Remain register (retain/review/retire + rationale).
- Support onboarding of new user subnets and creation of new ACRs.
- Support testing of new ACRs (connectivity validation, rule hits, troubleshooting).
- Support decommissioning of old ACRs with evidence traceable to the analysis register.
- Maintain an activity log (reports, workshops, ACR support).
Skills & Experience
- Experience in technical project management in network or infrastructure environments.
- Understanding of firewall rules, ACRs, connectivity flows and change governance.
- Ability to interpret technical reports and maintain structured documentation.
- Comfortable coordinating technical teams and business stakeholders.
