About the Role
We're hiring an Offensive Security Specialist to join a security consultancy/enterprise security team
serving clients across Belgium. You'll lead proactive security assessments — identifying weaknesses
before attackers do — across web applications, networks, cloud environments, and increasingly, AI/ML systems.
Key Responsibilities:
• Plan and execute penetration tests, vulnerability assessments, and red team engagements
across web, mobile, network, and cloud (AWS/Azure) environments
• Conduct social engineering and physical security testing where in scope
• Identify, exploit, and clearly document vulnerabilities with actionable, risk-prioritized
remediation guidance
• Build and maintain custom tooling/scripts to support testing efficiency
• Deliver technical and executive-level reports and present findings directly to client security
teams
• Stay ahead of emerging attack techniques, zero-days, and adversary tradecraft
• Mentor junior testers and contribute to internal methodology development
Requirements:
• 3+ years in penetration testing, red teaming, or offensive security
• OSCP required; OSCE, OSWE, OSEP, or CRTO a strong plus
• Strong scripting/programming ability (Python, C, PowerShell, or similar)
• Deep knowledge of OWASP Top 10, Active Directory attack paths, and cloud security
misconfigurations
• Experience with common offensive tooling (Cobalt Strike, Burp Suite Pro, Metasploit)
• Fluent English; French or Dutch a strong advantage for local client work
• Willingness to travel occasionally to client sites across Belgium
What's on Offer:
• Salary: €4,500+
• Company car
• Meal vouchers
• NET Allowances
• Group and Health insurances.
• Clear progression path toward Incident Response or Threat Intelligence specialisms
• Exposure to EU institution and multinational client environments
