Company Name
ARS-Rescue Rooter Overview
The Azure Infrastructure Engineer is a hands-on infrastructure role that designs, builds, migrates, secures, and operates production Azure infrastructure extending our on-premises VMware and Windows datacenter. Focus areas: Azure networking, hybrid connectivity, virtual machines and platform services, disaster recovery, and migration execution.
The role is DevOps-savvy, not DevOps engineering: the engineer uses Infrastructure-as-Code, Git, and pipelines to keep infrastructure repeatable and auditable, following and extending team standards.
The engineer partners with Infrastructure, Networking, Security, Database, and Application Development teams and external consultants.
Responsibilities
Key Responsibilities
Azure Infrastructure Engineering & Operations
Independently design, deploy, and maintain Azure infrastructure: landing zones, management groups, VMs, storage, backup, monitoring, and governance.
Troubleshoot connectivity, performance, access, and availability issues across VM, OS, network, DNS, firewall, and identity layers; perform root-cause analysis and implement durable fixes.
Develop runbooks and operational standards; participate in incident response, change management (CAB), maintenance windows, and on-call.
Hybrid Networking, DNS & Application Delivery Design and troubleshoot VNets, NSGs, routing/UDRs, hub-and-spoke or Virtual WAN, Azure Firewall, VPN Gateway, and ExpressRoute, including BGP and failover behavior.
Design name resolution across Azure and on-premises (Private DNS, DNS Private Resolver, conditional forwarding).
Implement private connectivity to PaaS services using private endpoints.
Support application delivery with Front Door, Application Gateway, load balancing, and WAF, including TLS certificate lifecycle and failure-mode design when an edge service or policy fails.
Work with Networking on firewall rules, IP addressing, NAT, and datacenter, branch, and third-party connectivity.
Migration Execution
Plan and execute VMware and Windows migrations to Azure: dependency assessment, Azure Migrate, lift-and-shift, test migrations, cutover, and post-migration support.
Produce cutover plans, validation checklists, and rollback criteria; execute off-hours production cutovers.
Support Azure infrastructure for SQL Server migrations (Always On to Azure SQL Managed Instance or SQL Server on Azure VMs).
Maintain hybrid domain controllers, DNS, and AD integration for Azure workloads.
Resiliency, Backup & Disaster Recovery
Design and test DR using Site Recovery, geo-redundant storage, and region/availability-zone design against RTO and RPO targets.
Operate Azure Backup and evaluate it against third-party backup and replication platforms for new Azure data stores; document and report recovery test results.
Platform Services Infrastructure
Provide infrastructure for App Service, Functions, Logic Apps, Service Bus, and API Management: VNet integration, private endpoints, identity, Key Vault, and monitoring.
Support AKS at the platform level (private cluster, CNI, node pools, ingress, managed identity) with Application Development.
Automation & Infrastructure-as-Code
Build, modify, and troubleshoot Terraform following team standards: modules, remote state, environment separation, and drift.
Use Git pull requests and code review; maintain Azure DevOps infrastructure pipelines, including approval gates and self-hosted agents reaching private endpoints.
Automate operations with PowerShell and Azure CLI.
Identity, Security & Governance
Apply Entra ID, RBAC, PIM, Conditional Access, and managed identities to enforce least privilege and segregation of duties.
Implement guardrails with Azure Policy, management groups, tagging, and Defender for Cloud.
Partner with Security, Compliance, and Audit on PCI DSS, NIST, and CIS controls, remediation, and audit evidence.
Observability & Cost Management
Build Azure Monitor and Log Analytics alerts, workbooks, and dashboards; tune alert noise and logging volume; use Application Insights for tracing.
Right-size and manage cost with Cost Management, Advisor, reservations, and savings plans, after establishing baselines.
Collaboration & Cross-Training
Share knowledge both ways: train teammates in Azure and cloud practices, and learn from them in their areas of expertise.
