Das bewegst du bei uns

• In this role, you will perform internal penetration tests independently and take over the technical coordination as well as the scoping of external security assessments.
• You will validate and verify discovered vulnerabilities within the Vulnerability Management framework to determine their actual exploitability and prioritize them based on real business risk.
• Following successful remediation by the responsible teams, you will independently conduct structured retests to ensure that the security findings are sustainably resolved.
• As part of Purple Teaming activities, you will purposefully simulate modern attacker techniques and work closely with the Detection & Response team to verify and continuously improve the effectiveness of existing SIEM, EDR, and monitoring controls.
• You will support new systems, critical architectures, and major infrastructure changes before they go live by conducting thorough security reviews and threat modeling.
• Your goal will be to identify potential attack paths and structural security weaknesses early on, effectively preventing them from becoming operational risks.
• Acting as a key sparring partner, you will collaborate cross-functionally with teams across Detection & Response, Vulnerability Management, Incident Management, IT, and Engineering to turn findings into real security improvements.
• You will actively drive the sustainable establishment and strategic development of our internal offensive security capability, directly shaping the overall security maturity of the company.

• You bring a deep understanding of infrastructure, cloud, and identity security, along with solid hands-on experience in web and API penetration testing according to established frameworks like OWASP.
• In your daily work, you are proficient with standard security tools such as Burp Suite, Nmap, BloodHound, PingCastle, and Git, and you possess strong scripting skills.
• Ideally, you hold recognized offensive security certifications such as OSCP, PNPT, CRTO, GWAPT, or possess a comparable practical qualification such as a BSI IT-Grundschutz Practitioner or Consultant.
• You have proven technical experience reviewing and testing complex environments, including Linux, Windows, Powershell, and Active Directory architectures.
• Experience working within German or European regulatory environments, such as ISO 27001, BSI IT-Grundschutz, TISAX, KRITIS, or NIS2, is considered a strong plus.
• You are characterized by strong documentation and reporting skills, enabling you to structure complex technical findings clearly and track them effectively for all stakeholders.
• Fluent German language skills as well as excellent English skills are required to ensure seamless and precise communication across all internal and external interfaces.

Das bekommst du von uns

• Your freedom: pro rata mobile working and flexible working hours
• Your team: open, familiar, appreciative culture including team events
• Your environment: dynamic, innovative and agile working environment
• Your role: high level of personal responsibility and freedom to implement your ideas
