Cybersecurity Engineer

CONTEXT

A sensitive public service is strengthening its cybersecurity maturity and needs a hands-on expert to keep critical networks and applications available, secure, and fast. The existing infrastructure relies on load balancing and firewall technologies that must be optimized with the discipline of a mission-critical environment. This is not a purely theoretical security role: it is about operating, maintaining, and improving the technical controls that stand between daily public services and disruption. The team is looking for someone who can combine deep network security knowledge with a calm, methodical approach to incident prevention and continuous improvement.

ACTIVITIES

• Operate, maintain, and optimize F5 load-balancing infrastructure.
• Configure and tune Fortinet firewalls to enforce security policies without harming performance.
• Monitor network and application availability, performance, and security events.
• Investigate vulnerabilities and propose practical remediation measures.
• Improve high-availability and resilience patterns for critical services.
• Document configurations, procedures, and operational runbooks.
• Collaborate with infrastructure, application, and security teams to raise overall maturity.

EXPECTED ACHIEVEMENTS

• Stronger security posture across network and application layers.
• High availability and predictable performance for critical services.
• Fewer operational surprises through better monitoring and documentation.
• Faster, safer response to security and availability incidents.
• A measurable improvement in cybersecurity maturity for a sensitive environment.

ENVIRONMENT

• F5 load balancing and Fortinet firewall technologies.
• Network and security operations for high-availability public services.
• Monitoring, incident management, and infrastructure optimization practices.
• A structured public-sector context with strong requirements for reliability, security, and continuity.
