• Oversee the setup and running of servers and applications, making sure everything integrates smoothly and performs well.
• Monitor and improve system performance, automate upgrades and deployments, and ensure our systems meet high security standards (like PCI-DSS for handling card payments).
• Work closely with other teams and partners to support smooth payment processes, share knowledge, and keep documentation up to date.

• Strong background in Windows Server, Active Directory, and virtualization tools like VMware or Nutanix.
• Experience with scripting and automation using Power Shell.
• Familiarity with cloud platforms (like Azure or AWS), monitoring tools (such as Splunk or Solar Winds), and high-availability systems.
• Knowledge of PCI-DSS standards and experience working on secure payment processing systems.
