Your mission

About the Role 
As Head of Red & Blue Team Security, you will lead our offensive and defensive security functions and own the development and execution of a comprehensive security assurance strategy. With a strong emphasis on penetration testing and adversarial simulation, you will embed security deeply into our Software Development Lifecycle (SDLC) and ensure that engineering teams consistently apply security-first principles. You will act as the key liaison between product development, compliance, legal, and external partners — translating complex regulatory requirements into practical, scalable security solutions across our platform.

Red & Blue Team Leadership

  • Drive penetration testing programs — both internal and coordinated with external partners — across infrastructure, applications, and cloud environments.
  • Oversee vulnerability assessments, threat intelligence, and security analyses, and ensure findings translate into actionable remediation plans.
  • Expand and mature the Red & Blue Team capabilities through new tooling, methodologies, and threat simulation frameworks 
Security Engineering & Strategy 
  • Take full ownership of technical and organizational aspects of product security.
  • Develop and implement security standards and processes, including Secure SDLC, Threat Modeling, and security testing integration into CI/CD pipelines.
  • Build and lead a specialized Security Engineering team alongside the Red & Blue functions.
  • Define and implement additional defensive strategies to strengthen the organization's overall security resilience.
 
Stakeholder Collaboration & Governance 
  • Partner closely with Product Development to integrate security requirements early in the development process and negotiate effective remediation timelines for identified vulnerabilities.
  • Work with Information Security, Data Protection, Compliance, and Legal teams to ensure platform-wide regulatory adherence.
  • Communicate and present the security strategy, architecture, andassuranceposture to customers, partners, regulators, and auditors.
  • Support the onboarding of new banking partners by ensuring platform security and stability meet required standards.
Organizational Impact 
  • Strengthen the visibility and authority of the security function within the broader organization.
  • Introduce and champion digital security tooling to enhance detection, response, and overall security operations.
  • Continuously raise the security bar across teams through training, awareness, and policy enforcement.

Your profile

What You Bring 
  • Several years of experience in product security or security engineering, ideally within regulated SaaS, fintech, or banking environments.
  • Proven hands-on experience leading Red Team and/or Blue Team operations, including penetration testing, threat hunting, and incident response.
  • Strong technical understanding of modern software architectures — particularly cloud-native environments, containerized systems (e.g., Kubernetes), and CI/CD pipelines.
  • Experience designing and implementing security processes within software development contexts (Secure SDLC,DevSecOps).
  • Familiarity with relevant regulatory frameworks such as ISO 27001, BAIT, DORA, or equivalent.
  • Ability to work in a structured and effective way across departments and with external auditors.
  • Fluent German and strong English skills, both written and spoken.
