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
