Helping to shape a secure software supply chain, including for dependencies, container images, artifacts, SBOM, signing, provenance, and trusted build and deployment processes
Analyzing and securing network connections and communication paths between platforms, data centers, external networks, and connected systems, including segmentation, firewalls, gateways, TLS/PKI, APIs, and machine-to-machine communication
Design and technical validation of identity, authentication, and authorization concepts for users, services, and workloads, as well as secrets, credentials, certificates, and key management
Ensuring the protection of data at rest, in transit, and during processing in close collaboration with platform and data engineering teams
Conducting threat modeling, vulnerability analysis, and technical validation of findings; deriving and implementing effective countermeasures
Further development of security monitoring, audit logging, and detection capabilities, as well as support for the technical analysis and resolution of security incidents
Participate in the security assessment of AI/machine learning infrastructures and AI-based applications, and implement security proofs of concept through to production-ready solutions

WHAT QUALIFICATIONS YOU SHOULD HAVE

A degree in computer science, cybersecurity, IT security, software engineering, or a comparable practical qualification
Several years of hands‑on experience in a technically oriented security role, e.g., as a Security Engineer, Platform Security Engineer, DevSecOps Engineer, or Penetration Tester
Very strong practical knowledge of Linux, networks, containers, and Kubernetes, as well as a solid understanding of modern cloud‑native and platform architectures
Practical experience in securing Infrastructure as Code, CI/CD/DevSecOps processes, and Kubernetes environments
In‑depth knowledge of network segmentation, TLS/PKI, IAM/RBAC, secrets, and credentials, as well as common authentication and authorization concepts
Experience with vulnerability analysis and penetration testing, as well as the ability to reproduce findings in practice, understand technical root causes, and implement appropriate countermeasures
Strong scripting or programming skills, e.g., in Python, Bash, Go, or a comparable language, particularly for automation and security testing
Ability to integrate security architecture with practical implementation and to collaborate effectively with platform, software, network, and data engineering teams
A structured, responsible work style and strong written and spoken English skills
Experience with red‑team, blue‑team, or purple‑team approaches and adversarial testing in complex platform environments
In‑depth knowledge of software supply chain security, e.g., SBOM, artifact signing, provenance, dependency security, or trusted build processes
Experience with Policy as Code, admission control, and runtime security, e.g., with OPA/Gatekeeper, Kyverno, Falco, or comparable solutions
Knowledge of security monitoring, detection engineering, and incident response in distributed Kubernetes or on‑premises environments
Experience securing large data platforms, object storage, databases, or data‑intensive systems
Knowledge of AI/machine learning security, e.g., protecting AI endpoints, training data, models, ML pipelines, or AI supply chains
Experience with highly secured, on‑premises, edge, or intermittently disconnected infrastructures
