Your mission in our team

Join Siemens Smart Infrastructure Cybersecurity team as an Application Security Expert and shape how we embed security into every layer of our development and operations ecosystem. You'll work at the intersection of cybersecurity, cloud infrastructure, and DevOps practices—designing and implementing security controls that protect critical infrastructure while enabling teams to move fast and innovate confidently. This role bridges the gap between security strategy and operational reality, ensuring that security becomes an enabler, not a bottleneck.

Challenges that await

Evaluate complex application architectures and integration scenarios, identifying security risks and recommending suitable controls aligned with ISO27001, IEC62443, and industry standards
Conduct risk assessments and consult business units on mitigating countermeasures, balancing security requirements with business objectives
Share expertise across the Siemens cybersecurity community, contributing to knowledge development and best practices
Represent the Smart Infrastructure Cybersecurity team in corporate initiatives and cross-functional security projects
Stay current with emerging threats, security frameworks (including AI Security frameworks like OWASP GenAI and MITRE ATLAS), and cloud security innovations

What will make your candidature stand out

A university degree in Computer Science, IT Security, or equivalent professional education
A minimum of 3 years' experience in application security architecture and endpoint protection
Strong knowledge of security standards and regulations (ISO27001, IEC62443) and proven ability to translate them into actionable security concepts
Solid understanding of Microsoft Azure Cloud and Microsoft Power Platform security architectures
Proficiency in English; German language skills are a valuable asset
Ability to think strategically while executing tactically—bridging security architecture with real-world implementation
Passion for continuous learning and staying ahead of the cybersecurity curve
Strong communication skills to translate complex security concepts for both technical and non-technical stakeholders

You'll thrive even more if you also bring

Experience with other cloud providers (AWS, Google Cloud) and their security models
Hands-on experience securing CI/CD pipelines, container technologies (Docker, Kubernetes), or Infrastructure-as-Code frameworks
Familiarity with AI Security Frameworks and their practical application in modern architectures
Experience with security automation and tooling in DevOps environments
Background in critical infrastructure protection or industrial cybersecurity
Contributions to open-source security projects or active participation in the cybersecurity community
