Security Engineer - Purple Team specialist H/F
About the role
Organization and team
Responsibilities
• Attack Veepee's perimeter the way a real adversary would: red team, penetration tests (grey/black/white/AI box), Active Directory attack paths, phishing campaigns and the business web based processes themselves (member journeys, seller flows, payment chains), hunting for logic flaws no scanner will ever find.
• Put our risk register and threat intelligence to the test: take a stated risk or an emerging threat and confirm it, or refute it, with a working attack scenario.
• Qualify what comes in from the outside: Bug Bounty reports (public and authenticated programs) and alerts escalated by our RAG agents during the cyber-watching rotation.
• Convert every confirmed attack path into something that runs without you: a detection rule, a hunting query, an automated control. If a bot can do it, we automate it.
• Build and improve the team's tooling: AI-assisted code audit, password auditing, secret hunting, attack-surface monitoring.
• Carry your findings through to remediation: explain the impact to product and infra teams, propose the fix, track it through our vulnerability-management lifecycle, and re-attack to prove it's closed.
• Share your discoveries with technical and business teams and spread security culture in accordance with day-to-day constraints.
Required skills
• The most important thing is motivation! Naturally curious profiles who enjoy proving or disproving that an attack works, and who don't consider the job done until it's fixed.
• Solid offensive skills: web and API penetration testing (OWASP), Active Directory attack techniques, and a taste for business-logic abuse beyond the technical stack.
• Investigation fundamentals: comfortable digging through EDR, logs and network data to reach a verdict, and turning attacker behavior into detection logic or solid on the offensive side with a strong will to grow there.
• Scripting and automation (Python, Bash, PowerShell); interest in AI-assisted security tooling (LLM-based code audit, agentic workflows) is a strong plus.
• You document what you do and make it reproducible.
• Strong communication skills: you can convince a product team to fix something they didn't want to hear about.
• Experience: ~3-5 years in offensive security, detection engineering or a mixed red/blue role.
• Language: French and professional English.
