Proven ability to design and implement automation solutions using tools such as Ansible, PowerShell, or equivalent scripting frameworks to reduce manual effort at scale. Strong background in patch and vulnerability management for Windows Server and virtualization infrastructure, with the ability to interpret and act on vulnerability data. Experience in datacenter operations, including hardware lifecycle management, asset tracking, and environmental monitoring for power and cooling systems. Solid understanding of IT service management frameworks (ITSM/ITIL), change management processes, and audit readiness in enterprise environments. Familiarity with cloud technologies and hybrid infrastructure concepts, including experience with platforms such as Azure Arc or equivalent cloud management tooling. Demonstrated ability to apply AI and machine learning technologies for predictive maintenance and advanced infrastructure troubleshooting. Strong analytical and communication skills, with the ability to document complex processes clearly and engage effectively with stakeholders at all levels. ### Advanced to fluent English What we offer We are curious minds that come from a broad range of backgrounds, perspectives, and life experiences.
