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.
  • Infrastructure know-how: You are confident in working with Windows Server architectures, Active Directory, Entra ID (Azure AD), Conditional Access, and Group Policy Management, and possess strong expertise in PowerShell to automate processes efficiently.
  • 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.
  • Nice-to-have: Experience with modern authentication protocols (OAuth 2.0, OIDC, SAML, SCIM) as well as Entra ID Governance.

What we offer

  • There are many reasons to work at PORR:
  • Happiness: You are part of a highly motivated and collegial team working together on challenging tasks and exciting projects.
  • Career: Individual training and development opportunities await you, so you can progress as you wish.
  • Work-Life Balance: Autonomy to promote a balanced life is a matter of course for us - therefore, we offer both flexible working hours and home office days.
  • Good money: You will receive an annual gross salary starting from €65,000 or €75,000 for the senior role.
  • If you bring special skills or experience, there is also the possibility of more.
