For the Senior IT Administrator level

Candidates considered for the Senior IT Administrator level should additionally bring:

• 5+ years of relevant hands-on IT administration or systems engineering experience, ideally in a technical or engineering-driven environment.
• Strong hands-on expertise across Linux and macOS, with the ability to independently troubleshoot complex endpoint and system issues.
• Proven experience taking ownership of MDM, IAM, SSO/MFA, endpoint security, networking, and access management.
• Strong networking knowledge with practical experience configuring and troubleshooting VPNs, VLANs, DNS, DHCP, routing, Wi-Fi, and firewalls.
• Experience independently owning technical projects from solution design and implementation through documentation and ongoing operation.
• Strong troubleshooting skills across endpoints, networks, cloud services, identity, and infrastructure, with the ability to resolve complex issues without relying primarily on external providers.
• Experience using scripting and automation to improve IT operations and reduce repetitive manual work.
• Ability to proactively identify weaknesses in an existing IT environment and independently propose and implement secure, scalable improvements.
• Experience acting as a technical escalation point and supporting or mentoring less experienced colleagues.
• Ability to work confidently with Engineering and DevOps teams and communicate effectively with highly technical stakeholders.
• A strong security mindset and interest in taking increasing ownership of Information Security, ISO 27001, TISAX, and ISMS-related topics.

Previous hands-on experience supporting ISO 27001, TISAX, an ISMS, or security audits is an advantage for the Senior level, but not required.

• Are comfortable working independently while knowing when to ask for help.  

• Enjoy working with highly technical software engineers and learning from subject-matter experts.  

• Are curious about new technologies and continuously develop your skills.  

• Want to broaden your experience beyond traditional IT administration into Information Security, ISO 27001, and TISAX.
