IT-Administrator (m/w/d) (m/w/d) in Teilzeit

About This Opportunity

We are representing a confidential client in the sustainable energy sector based in Munich. They are seeking an experienced IT Administrator to establish and maintain their IT infrastructure on a part-time basis. This is not an entry-level position—our client needs someone who has already owned Microsoft 365 administration in a production environment and can bring order to their growing technical landscape.

The organization has scaled rapidly without dedicated IT administration. Microsoft 365, domain management, and email systems have been managed ad-hoc by leadership and team members juggling other responsibilities. With continued growth and increasing complexity around customer and partner communications, they need a professional to take ownership, clean up existing systems, and maintain them reliably going forward.

Responsibilities

• Conduct initial cleanup of accounts, licenses, roles, and permissions across Microsoft 365 and Entra ID; close orphaned mailboxes, enforce MFA and Conditional Access comprehensively, and establish proper SPF, DKIM, and DMARC configuration for all domains
• Administer Microsoft 365 and Entra ID: manage users, groups, licenses, roles, permissions, security policies, and devices; monitor and respond to security alerts from Defender and Entra ID
• Maintain tenant hygiene: review and clean up third-party application consents, Enterprise Apps, and application permissions to mailboxes and data
• Execute employee onboarding and offboarding across all access points (Microsoft, HubSpot, Atlassian, GitHub, AI tools, and other SaaS services) using scripted workflows rather than manual checklists
• Manage domains, DNS, and email infrastructure including mailbox migrations; ensure deliverability and spam protection in both directions, monitor sender reputation and blacklists, and coordinate email sending across HubSpot, Mailchimp, internal platforms, and invoicing systems
• Administer HubSpot user and permission management and its integration with Microsoft services (authentication, calendar, mailboxes)
• Manage AI tool access: team accounts for Claude, GitHub, and similar platforms; connectors and MCP integrations with Microsoft 365, HubSpot, and Jira; establish data access and privacy rules
• Automate your own work: build scripts and small tools using Claude Code or comparable platforms; maintain AI-assisted runbooks and documentation; deflect recurring IT requests through automated assistants
• Serve as first point of contact for IT questions from the team and coordinate with external service providers and software vendors

What We're Looking For

• Multiple years of demonstrated experience administering Microsoft 365 and Entra ID in a production business environment—this is not an entry-level role
• Previous experience setting up or remediating an email environment; solid understanding of how SPF, DKIM, and DMARC work together and what happens when they don't
• Confident handling of DNS and domain administration
• Scripting capability with PowerShell or Microsoft Graph sufficient to automate processes rather than clicking through them manually
• AI is part of your daily workflow: you actively use Claude, ChatGPT, Copilot, or similar tools for scripting, analysis, and documentation, and can provide specific examples of what you've automated with them
• Independent, structured work approach with strong documentation habits and proactive communication before issues escalate
• Clear communication in German with non-technical colleagues
• Nice to have: HubSpot or comparable CRM administration experience, AI coding tools (Claude Code, Cursor), automation platforms (Make, Power Automate), MCP integrations and AI assistants on enterprise data, tenant migrations, foundational information security and data protection knowledge (ISO 27001, BSI-Grundschutz), Microsoft certifications such as MS-102 or SC-300 (welcome but not a substitute for hands-on experience)
