Infrastructure Security Specialist

As an Infrastructure Security Specialist, you ensure that technical security controls within our IT environment are properly designed and effectively implemented. You combine security engineering with a structured governance mindset and translate security principles into concrete technical configurations. In doing so, you strengthen the reliability of our technical control framework and contribute directly to a secure and sustainable IT landscape. Without this role, the connection between security policy and technical implementation weakens, which can reduce the effectiveness of our security controls.

Concretely, you will work on:

Defining and maintaining technical security standards and by working closely with engineers and IT teams to structurally improve security. In addition, you will focus on:

• Defining and maintaining security baselines for Microsoft 365, Azure, endpoints, infrastructure and network components
• Translating security principles into practical configuration standards and reviewing new technologies and projects from a security architecture perspective
• Supporting secure software development practices and DevSecOps integration, including secure coding, dependency scanning and CI/CD security controls
• Performing technical control reviews such as RBAC, encryption, segmentation and system hardening
• Supporting vulnerability management and ensuring that security requirements are embedded in change and project processes

Team

You will not do this alone, but together with a group of engaged and motivated colleagues. In this role, you report to the Information Security Officer (ISO) and work closely with Security Engineers and various IT teams. You operate at the intersection of technical specialists and governance stakeholders and ensure that security controls are not only defined, but also technically sound and properly implemented. The role combines operational involvement with structural improvements to the security framework.

For this role, we are looking for a technically skilled security professional who can translate risk and policy requirements into concrete technical controls. You work in a structured way, are detail-oriented and feel comfortable challenging technical designs from a security perspective.
