Senior Infrastructure Systems Engineer

Hybrid Software Helix is seeking a Senior Infrastructure Systems Engineer to join a small internal IT department that provides IT support to its operating companies worldwide. The successful candidate will help implement the organisation’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, as part of this role, you will be expected to deal with critical system issues as and when they occur, which may occasionally involve out-of-hours work. 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 position reports directly to the Chief Information Officer.
