Summary

As a Senior Systems Engineer, you will spearhead infrastructure design and modern delivery initiatives within an enterprise IT organization. This role demands an automation-first approach, transitioning traditional infrastructure operations into scalable, software-defined practices. You will drive full-stack engineering across cloud, on-premises, virtualization, and network platforms to support product development and enterprise teams effectively.

We are seeking a highly skilled, forward-thinking engineer with deep expertise in Linux systems, robust automation capabilities, and commitment to DevOps methodologies. You will lead Infrastructure as Code (IaC) initiatives using Terraform and Ansible, optimize hybrid environments, and champion the integration of AI-assisted engineering tools to accelerate delivery and ensure code quality. While Linux is the primary focus, familiarity with Windows Server environments and hybrid cross-platform management is highly valued.
