Modern Technology Stack: You will work with enterprise firewall solutions, cloud security platforms, SIEM technologies, endpoint protection systems, and modern hybrid cloud environments across AWS and Microsoft Azure.
Growth Opportunities: We invest heavily in professional development. You will receive support for advanced certifications, leadership training, and attendance at cybersecurity conferences such as Infosecurity Europe and Gartner Security and Risk Management Summit.
Key Responsibilities:
Network Security Leadership: Lead the design, implementation, and continuous improvement of enterprise network security infrastructure across multiple business environments.
Threat Detection and Incident Response: Oversee security monitoring operations, vulnerability management, and incident response activities to minimize operational risk and downtime.
Security Architecture: Collaborate with infrastructure and cloud engineering teams to develop scalable and secure network architectures that align with business growth.
Compliance and Governance: Ensure systems and security processes comply with industry regulations, security frameworks, and internal governance standards.
Team Leadership: Mentor security analysts and network engineers while fostering a proactive and collaborative cybersecurity culture across the organization.
Risk Management: Conduct regular security assessments, penetration testing coordination, and infrastructure audits to identify and mitigate potential threats.
Stakeholder Collaboration: Present security strategies, risk findings, and remediation plans to senior leadership and non-technical stakeholders in a clear and actionable manner.
Requirements
Do you have experience in Network security?, 7+ years of experience in network security, cybersecurity operations, or infrastructure security, with at least 2 years in a senior leadership or management role.
Technical Expertise: Strong knowledge of enterprise firewalls, VPN technologies, IDS/IPS systems, endpoint security, SIEM platforms, cloud security, and network segmentation strategies.
Certifications: Industry certifications such as CISSP, CISM, CCNP Security, CEH, or equivalent are highly valued.
