Job description:


We are seeking an experienced Senior Infrastructure, Cloud & Network Engineer to design, build, automate, and support secure and resilient technology environments across Microsoft Azure, hybrid cloud, network, security, and on-premises platforms.


The role requires strong expertise in Azure infrastructure, enterprise networking, multi-vendor security, Infrastructure as Code, and production troubleshooting. The successful candidate will collaborate with application, security, database, and support teams to deliver standardized, reliable, and operationally ready infrastructure solutions.


The Main Responsibilities:

  • Design, provision, and support Microsoft Azure infrastructure, including VNets, virtual machines, storage accounts, resource groups, backup vaults, Application Gateway, and Web Application Firewall.
  • Implement and maintain secure connectivity using VPN, OpenVPN, ExpressRoute, VNet peering, DNS, private DNS, and IP allow-listing.
  • Configure and troubleshoot routing, switching, wireless, SD-WAN, and multi-vendor firewall environments.
  • Administer network-security platforms such as Cisco, Fortinet, Palo Alto, and Azure Firewall.
  • Implement Infrastructure as Code using Azure Bicep or Terraform and support automated deployments through Azure DevOps YAML pipelines.
  • Configure certificates, WAF policies, listeners, routing rules, and access-control policies.
  • Support Windows Server, Active Directory, Group Policy, Entra ID synchronization, domain trusts, and VM operations.
  • Implement and troubleshoot SFTP, FTP, SSH key exchange, public-key authentication, and secure file-transfer integrations.
  • Support backup, disaster recovery, migration, failover, infrastructure decommissioning, and resilience-readiness activities.
  • Troubleshoot complex production issues involving connectivity, DNS, certificates, disk capacity, access, and infrastructure health.
  • Create and maintain technical runbooks, implementation procedures, reference architectures, and knowledge-transfer documentation.
  • Coordinate effectively with application, security, database, cloud, and operations teams.


What We Look For in a Candidate:

  • Strong hands-on experience in Microsoft Azure infrastructure engineering.
  • Expertise in Azure networking, compute, storage, backup, Application Gateway, WAF, and security-edge services.
  • Strong enterprise networking knowledge, including TCP/IP, IP addressing, routing, switching, DNS, VPN, ExpressRoute, and VNet peering.
  • Hands-on experience with multi-vendor firewalls, preferably Cisco, Fortinet, Palo Alto, or Azure Firewall.
  • Working experience with wireless and SD-WAN technologies.
  • Experience with Azure Bicep or Terraform and Azure DevOps YAML pipelines.
  • Knowledge of Windows Server, Active Directory, Group Policy, Entra ID, and identity dependencies.
  • Strong production troubleshooting, documentation, communication, and cross-functional coordination skills.
  • Hands-on CrowdStrike Falcon experience covering console administration, sensor lifecycle, prevention policies, detections, investigations, host containment, response operations, and troubleshooting.
