  • Collaborate with cross-functional teams (network, security, application, operations) and communicate clearly with stakeholders, including those without a technical background.
  • Provide support for additional firewall platforms as needed, including SAP-related or other vendor solutions.
  • Apply and maintain security best practices and compliance in all tasks and projects.
  • Proven ability to execute projects independently, escalate effectively, and foster collaboration when required.
  • Strong root-cause analysis, troubleshooting, and remediation skills across both network and security platforms.
  • Exceptional verbal and written communication skills, especially when interacting with non-technical stakeholders.
  • Experience with documenting technical work for knowledge sharing and operational continuity.
