Senior Cybersecurity Engineer

Job Title: Senior Cybersecurity Engineer – Offensive & Defensive Security

Location: Deurne (Hybrid – 3 days onsite per week)

Role Summary:

We are looking for a highly skilled, technically hands-on Cybersecurity Engineer with deep expertise in offensive and defensive security operations. The ideal candidate will combine strong technical proficiency in threat detection, incident response, and penetration testing, with a solid understanding of cybersecurity engineering practices. This role is not governance/compliance-heavy — we’re looking for someone who thrives in dynamic environments, engages directly with cyber threats, and builds security systems from the ground up.

Key Responsibilities:

🔐 Offensive Security / Red Teaming

• Conduct penetration tests on infrastructure, networks, applications, and APIs.
• Simulate sophisticated attack vectors and APT scenarios to identify vulnerabilities.
• Design and execute ethical hacking engagements and vulnerability assessments.
• Use frameworks such as OWASP, MITRE ATT&CK, and NIST 800-115.

🛡️ Defensive Security / Blue Teaming

• Operate and enhance SIEM platforms (e.g., Splunk, Sentinel, QRadar).
• Monitor threat intelligence feeds and respond to live security incidents.
• Conduct root cause analysis of breaches and propose mitigation strategies.
• Engage in threat hunting, malware analysis, and behavior-based detection.

🔧 Security Engineering & Architecture

• Design and implement secure software development practices (DevSecOps).
• Configure and harden firewalls, IDS/IPS, zero-trust architectures, and endpoint protection.
• Build and maintain secure authentication and cryptographic systems.

Required Skills & Qualifications:

• 5+ years of technical cybersecurity experience, preferably in offensive/defensive security roles.
• Proven hands-on experience with penetration testing, ethical hacking, and red teaming.
• Strong knowledge of SIEM, EDR, IDS/IPS, malware analysis, and threat intelligence.
• Experience working with firewalls, zero-trust, and advanced network architectures.
• Familiarity with cryptography, API security, and secure SDLC methodologies.
• Fluent in scripting languages (e.g., Python, Bash, PowerShell).
• Deep understanding of OWASP Top 10, MITRE ATT&CK, NIST frameworks.

Preferred Certifications:

• Offensive Security Certified Professional (OSCP)
• Certified Ethical Hacker (CEH)
• GIAC Penetration Tester (GPEN), GWAPT
• CISSP, CCSP, SSCP
• Other ISACA or OWASP technical credentials

Nice to Have:

• Experience in cloud security (AWS, Azure, GCP).
• Experience with container security (Docker, Kubernetes).
• Familiarity with ISO27001, but from a technical implementation angle, not just audit/compliance.

What Success Looks Like:

• You identify and fix vulnerabilities before they’re exploited.
• You lead red/blue team engagements that significantly improve our security posture.
• You automate detection and response to real-world threats using advanced tools.
• You’re hands-on, proactive, and always ahead of the adversarie
