Position Overview

As a Senior Infrastructure Engineer (Linux & Cloud Automation) at Synapse360, you are responsible for the operational delivery and automation of Linux-based infrastructure across managed service customers.

You will own the end‑to‑end patching lifecycle for Linux server estates using Ansible, and manage Azure Update Manager policies for Linux VMs across Azure. You will manage and remediate backup operations for Linux workloads via Azure Backup, implement infrastructure‑as‑code deployments using Bicep and ARM templates, maintain CI/CD pipelines via Azure DevOps, and handle escalations from the Infrastructure team.

This is a demanding, hands‑on engineering role requiring strong proficiency in Linux administration, automation tooling, Microsoft Azure, and DevOps practices.

- Proficiency in Microsoft Azure — specifically Linux VM management, Azure Update Manager, Azure Backup, Recovery Services Vaults, NSG/UDR configuration, and Azure networking.
- Strong Linux administration skills across RHEL, CentOS, Ubuntu, and Oracle Linux — package management, service management, log analysis, and security hardening.
- Experience with Infrastructure‑as‑Code using Bicep and/or ARM templates for repeatable Azure deployments.
