Cyber Defense Engineer

Location: Cork
Type: Full-Time
Salary: €80,000 – €100,000

A security-focused organisation is bringing in an experienced engineer to support live threat investigation, platform analysis, and incident-driven problem solving across customer environments. This role is hands-on and technical, with a strong emphasis on understanding how attacks unfold and how controls behave under pressure.

The Role

You’ll analyse security events, validate detections, and help organisations respond effectively to real-world threats. The work blends investigation, tooling analysis, and clear technical guidance—cutting through noise and focusing on what actually matters during an incident.

What You’ll Do

  • Investigate suspicious activity across endpoint, network, and cloud telemetry

  • Analyse logs and alerts to confirm impact, scope, and attacker behaviour

  • Support containment and remediation through technical guidance

  • Troubleshoot detection and response tooling when behaviour isn’t as expected

  • Produce concise technical findings for stakeholders

  • Contribute to improving how threats are detected and handled

What You’ll Bring

  • 5+ years in security operations, incident response, or defensive engineering

  • Strong experience with SIEM, EDR, and security monitoring tooling

  • Solid grounding in networking, Windows, and Linux systems

  • Understanding of attacker techniques and modern threat frameworks

  • Calm, analytical approach during high-pressure situations
