Hybrid Software Helix is seeking a Senior Infrastructure Systems Engineer to join a small internal IT department that provides support to its operating companies worldwide.
Reporting directly to the chief information officer, this role would be ideally suited for a well-rounded, knowledgeable individual who understands the complexity and challenges of modern infrastructure and has a strong grasp of Azure adoption within an enterprise.
The successful candidate will help implement the organization's cloud-adoption strategy and contribute to the development of processes in anticipation of ISO27001 certification. The role, therefore, requires a highly technical, technology-passionate professional with experience in maintaining and deploying infrastructure systems, server maintenance, and project work, as well as a strong working knowledge of Microsoft Azure.
The core infrastructure within the business is a multi-site mixture of Windows (2022/2025 Servers/Active Directory), HP-based networking and next-generation firewalls. The department works with products such as vSphere, Microsoft Azure, Atlassian tools, Veeam, Microsoft 365, Intune and many more.
In addition to project-based work you will be expected to deal with critical system issues as and when they occur, which may occasionally involve out-of-hours work.
