Senior Cybersecurity Engineer, Limassol

Emerald Zebra Executive Search is seeking a Senior Cybersecurity Engineer based in Limassol, Cyprus.

Our client is a PCI DSS Level 1 payment-orchestration platform. We are seeking an experienced, proactive Senior Cybersecurity Engineer to strengthen the security team and protect our infrastructure across endpoint, email, network and web-facing payment platforms.

The role combines senior security operations — incident ownership, detection engineering and L2/L3 escalation — with hands-on engineering and administration of the enterprise security stack (EDR, email security, DLP, SASE/VPN, WAF, DDoS).

The successful candidate will also be the day-to-day technical owner of our managed out-of-hours detection & response service and will contribute to security governance, architecture and documentation under our PCI DSS programme.

This is a senior individual-contributor role for someone who can own incidents end-to-end, raise the maturity and resilience of the function, and operate calmly in a fast-paced, compliance-driven environment.

Key responsibilities

• Serve as the senior in-house L2/L3 escalation point during business hours and own incident response end-to-end: triage, containment, eradication, recovery, root-cause analysis and post-incident review.
• Act as technical owner of the co-sourced MDR / managed security service providing out-of-hours L1/L2 coverage — maintain the escalation matrix, validate handoffs and oversee service quality and SLAs across the 24/7 window.
• Operate, tune and harden the enterprise security stack (SIEM/XDR, EDR, email security, DLP, SASE/VPN, WAF, DDoS) and maintain detection content, correlation rules and incident-response playbooks.
• Drive the implementation and evidencing of PCI DSS technical controls (Requirements 1, 4, 5, 7, 8, 10, 11, 12) with the Cybersecurity Lead and QSA, including Cloudflare Layer 7 / WAF / DDoS architecture input.
• Review phishing and suspicious email, investigate malware and anomalous behaviour, handle senior security tickets, and support periodic access reviews and audits.
• Author and maintain SOPs, runbooks and incident reports; mentor operational staff and reduce single-point-of-failure risk.

Required Qualifications

• 7+ years' hands-on experience in cybersecurity / security operations / security engineering, including time in a senior or lead capacity.
• Demonstrated experience implementing and evidencing controls under PCI DSS (and/or ISO 27001, NIST CSF, CIS Benchmarks).
• Proven incident-response ownership across the full lifecycle, from triage to post-incident review.
• Experience working alongside or managing an MDR / managed SOC service, including escalation governance and SLA oversight.
• Degree in Computer Science, Information Security or a related field, or equivalent practical experience.

Required Skills & Competencies

• Deep, hands-on SIEM/XDR and EDR operation, tuning and detection engineering.
• Administration of email security, DLP, SASE and VPN platforms.
• WAF, API security and DDoS mitigation (Cloudflare or comparable edge platforms).
• Strong grasp of network-security fundamentals — TCP/IP, DNS, HTTP/S — and common attack techniques.
• Excellent documentation (SOPs, runbooks, incident reports) and calm, clear stakeholder communication under pressure.

Nice-to-have / Preferred

• Hands-on Check Point Harmony (Endpoint, Email & Collaboration, SASE) and/or Check Point managed-services experience; Cloudflare Enterprise (WAF, DDoS, Bot Management).
• Industry certifications (CISSP, GIAC GCIH/GCIA/GMON, Check Point, Cloudflare, Security+) and prior payment-gateway, fintech or PCI DSS Level 1 experience.
