As a Senior Offensive Security Advisor, you contribute to identifying, analyzing, and remediating threats targeting the organization’s exposed systems. You conduct advanced penetration tests, code reviews, threat modeling, and various offensive security activities. Your role goes beyond simply producing reports: you collaborate actively with security and infrastructure teams to understand the root causes of vulnerabilities, recommend practical solutions, and assist in their implementation. You will have access to a diverse scope, cutting‑edge offensive tools, and the opportunity for continuous testing to strengthen the organization’s overall cybersecurity posture. More specifically, you will be required to:

• Plan and execute offensive assessments: penetration tests, threat modeling, and targeted technical analyses.
• Detect, analyze, and prioritize vulnerabilities, then support teams in applying concrete fixes.
• Collaborate closely with IT and security teams to understand root causes and deploy prevention and detection mechanisms.
• Produce clear, actionable reports including observations, technical evidence, and prioritized recommendations.
• Explore, map, and maintain visibility over exposed assets while continuously monitoring the external perimeter.
• Explain threats, present risks, and lead technical workshops to support decision‑making.
• Design and improve innovative offensive methods, tools, and approaches.
• Manage your mandates autonomously, including planning, prioritization, and coordination with stakeholders.
