Deep expertise in network security technologies (firewalls, VPN, proxy, load balancing)
Solid understanding of cloud security and secure access architectures
Experience in incident detection, response, and remediation
Automation and scripting capabilities for operational improvement
Knowledge of operating systems commonly used in enterprise network environments
Understanding of security standards and cryptographic protocols
Continuous learning mindset; professional certifications in network and security domains are considered a strong asset
Profile & Soft Skills
Strong analytical and problem-solving mindset with the ability to deliver pragmatic solutions
Clear communicator capable of translating complex technical concepts for non-technical audiences
Leadership ability, mentoring junior team members and sharing expertise
Collaborative team player, comfortable working with business and technical stakeholders
Autonomous, well-organized, and able to manage multiple priorities effectively
