Security is our foundation – shape the digital future with us! 
Cybersecurity is at the heart of our innovative digital solutions. As a Security Test Expert (f/m/d), you will ensure the robustness and integrity of our Railigent X IoT Platform – an open, AI-powered IoT platform in the AWS Public Cloud that revolutionizes rail asset management. Join our central Test Expert team, which provides, develops, and continuously improves the test infrastructure for our product development teams, and conducts comprehensive integration and customer-specific system tests. Support our agile teams and actively build the secure digital future at Siemens Mobility! 

Your responsibilities - Secure and future-oriented:
  • Proactively advise agile development teams on integrating security best practices throughout the software development lifecycle (SDLC) and implement security tools in CI/CD pipelines. 
  • Be responsible for the conception, development, and execution of comprehensive security tests, as well as the creation of associated test strategies and specifications. 
  • Thoroughly analyze test results, accurately identify vulnerabilities, and meticulously detail them. 
  • Collaborate closely with agile product development teams and other security experts to support the remediation of identified vulnerabilities and implement preventive measures. 
  • Stay continuously informed about current threats, vulnerabilities, and security technologies to continuously improve our security standards. 

What you should bring - Well-founded and responsible:
  • A successfully completed degree in Computer Science/IT Security or a comparable qualification, combined with meaningful professional experience in Security Testing. 
  • Profound knowledge of web application security standards (e.g., OWASP Top 10) and practical experience with common security testing tools and methods (e.g., ZAP, SAST/DAST). 
  • Experience with the security of SaaS products and cloud environments (e.g., AWS, Azure) and familiarity with agile development methodologies (e.g., Scrum, SAFe). 
  • Python knowledge is required. Additional programming and/or scripting skills are desirable for developing test automation or verifying vulnerabilities. 
  • Strong analytical skills, a structured way of working, and a high degree of responsibility. 
  • Proficient English is required. 
  • Ideally, you possess relevant security certifications (e.g., OSCP or ISTQB Security Tester). 

What you can expect from us: 
A flexible working model to promote a better work-life balance, health insurance, and access to our on-site medical center. Two volunteering days per year and four additional bridge days annually. In addition, you’ll have access to outstanding discounts on Siemens and Bosch brands, and Siemens Learning Platforms offering internal courses and external platforms such as Coursera, Udemy, and LinkedIn Learning.

This sounds exciting to you, then send us your application – in English – and we will get back to you!
