• Monitor system performance, troubleshoot incidents, and lead recovery efforts to maintain high availability of payment and telephony platforms.
• Automate processes with PowerShell and other tools, implement proactive monitoring, and ensure compliance with PCI-DSS and security standards.
• Collaborate with internal teams and external partners on integrations, provide technical support, and participate in on-call/out-of-hours support.

Requirements include:

• Strong Windows Server administration (AD, DNS, DHCP, Group Policy, IIS, SQL Server, .NET), with experience in VMware and system monitoring tools.
• Background in secure, high-availability environments, with knowledge of PCI-DSS, disaster recovery, clustering, and networking fundamentals.
• Scripting skills (PowerShell), plus experience with automation, system integration, and performance optimisation.
• Strong troubleshooting, communication, and collaboration skills, with a DevOps mindset and willingness to learn new technologies (Linux, cloud, telephony).
