    Job Technologies

    Your role in the team

    • Active Directory: You are responsible for the operation, administration, and further development of our Active Directory infrastructure – Domain Controllers, replication, forest and domain design, Group Policies, schema, and permission models are in your hands.
    • You ensure a clean, secure, and future-proof Active Directory environment.
    • As a Senior, you drive strategic topics such as AD modernization, tiering models, migrations, or hybrid identity architectures with full technical depth – including integration with Entra ID (Azure AD Connect/Cloud Sync) as the foundation for Conditional Access.
    • IAM & User Management: You will drive our Identity & Access Management solutions forward – from Joiner/Mover/Leaver processes to role and permission concepts, as well as the management of identities, roles, and permissions across all relevant systems.
    • You configure and manage Conditional Access policies and MFA procedures in Entra ID to ensure risk-based, context-aware access control.
    • You ensure that user access is managed securely, auditable, and automated – including structured access control and regular reviews.
    • Privileged Access Management: You develop and oversee concepts in Privileged Access Management – privileged accounts, vaulting, Just-in-Time access, session monitoring, and break-glass procedures.
    • You ensure that critical access is secured, controlled, and auditable.
    • Automation: You develop and implement automations for recurring infrastructure and identity tasks using PowerShell – to make processes more efficient, stable, and scalable.
    • Modernization & Standardization: You actively contribute to the standardization and renewal of the technologies and components used – from legacy AD structures to modern identity platforms.
    • As a senior, you will shape roadmaps and architecture decisions and influence how our identity landscape will look in the coming years.

    Our expectations of you

    Education

    • Education & Professional Experience: You have completed a technical education (HTL/FH/University) in the IT field and have at least 5 years of relevant professional experience with a focus on IT infrastructure (for the senior role, at least 10 years).

    Qualifications

    • IT all-rounder with a service mentality: You see yourself as a technical generalist with a broad knowledge base and impress with a professional demeanor as well as a strong service orientation.

    • Security & Compliance Awareness: You always consider identity and access management topics from a security perspective – Least Privilege, auditability, and traceability are not just buzzwords for you, but self-evident principles.
    • Analytical thinking & structured working approach: A structured, independent working style, the ability to methodically solve complex error patterns, as well as the diligence to juggle many parallel topics without loss of quality, distinguish you.
    • Communication skills: You have very good German and good English skills for collaboration in an international environment.
    • As a senior, you actively share your knowledge with colleagues and serve as a sparring partner for the team.

    Experience

    • Excellent plus: Experience with established PAM solutions such as Fudo, Wallix, or Cyberark – if you bring this with you, you have our full attention.
    • Experience with Identity Governance Tools (SailPoint, Saviynt, OneIdentity) is a clear plus.
