Security Engineer - Purple Team specialist H/F

Pioneer of online flash sales since 2001, Veepee is a key player in European e‑commerce, collaborating with over 7,000 brands to offer highly discounted products for a limited time. With a turnover of 3.3 billion euros incl. VAT in 2024 and about 5,000 staff across ten countries, our cybersecurity team brings together Red/Purple/Blue capabilities and risk & compliance experts to secure business operations.

The threat detection & incident response team runs fully in‑house—covering detection engineering, case management and response, threat intelligence, and the vulnerability lifecycle. Automation and AI lie at the core: agents triage alerts 24/7, an LLM pipeline audits our code, and every confirmed finding fuels a remediation loop with product teams.

Responsibilities and Qualifications

• 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.
• 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.

Benefits

• Variable bonus
• The dynamic and creative environment within international teams
• Variety of self‑education courses on our learning platform
• Participation in meetups and conferences locally and internationally
• Flexible office with up to 2 days at home
