The Manager, IT Infrastructure & Cloud Operations will define scalable systems and policies to support Company's growth, with ownership spanning enterprise network infrastructure, data center operations, server and storage systems management, cloud operations across multi-cloud environments, SOX/audit compliance documentation, and capacity planning.

Essential Functions

Network Architecture & Cloud Connectivity:

• Design, maintain, and optimize the company's local and wide area network topology including performance tuning, capacity planning, and traffic balancing across global sites; extend network design principles into cloud virtual network architectures across AWS, Azure, and Oracle Cloud Infrastructure (OCI).

• Deploy, configure, and manage enterprise network infrastructure including Fortinet FortiGate firewalls, Arista data center and storage switches, and Juniper Mist access points; maintain associated documentation and contracts; integrate on-premises network policies with cloud-native security controls including AWS Security Groups and Network ACLs, Azure Network Security Groups, and OCI Security Lists.

• Manage WAN connectivity including internet circuits, SD-WAN data lines, and network topology documentation for all domestic and international locations, including hybrid connectivity solutions such as AWS Direct Connect, Azure ExpressRoute, and OCI Fast Connect.

• Provide remote management and standardization of network infrastructure across all remote office locations worldwide, including cloud-resident workloads and SaaS application delivery optimization.

Data Center & Facilities Operations:

• Oversee equipment room operations including rack organization, structured cabling, UPS capacity planning and load balancing across all facilities, complemented by cloud infrastructure cost management, rightsizing, and resource tagging governance across multi-cloud environments.

• Maintain server infrastructure including physical and virtual environments; manage VMware vSphere and/or Hyper-V hypervisor platforms for compute virtualization across on-premises deployments and oversee equivalent cloud compute services including AWS EC2 Auto Scaling, Azure Virtual Machine Scale Sets, and OCI Instance Pools for hybrid workload placement.

Linux Systems & Cloud Operations:

• Administer and maintain enterprise Linux environments including Red Hat Enterprise Linux and Ubuntu Server, covering installation, patching, performance tuning, and lifecycle management across both on-premises and cloud-hosted virtual machine instances in AWS EC2, Azure Virtual Machines, and OCI Compute.

• Design and manage cloud landing zones, account/subscription structures, and governance frameworks across AWS Organizations, Azure Management Groups, and OCI Compartments, ensuring consistent policy enforcement, identity federation, and spend visibility.

• Implement Infrastructure as Code practices using tools such as Terraform, Ansible, or Azure Bicep to standardize and automate cloud resource provisioning; develop and maintain IT operational procedures for preventive maintenance, change management, and infrastructure standards across both on-premises and cloud environments.

• Provide technical guidance to helpdesk staff for routine infrastructure responsibilities.

Storage Management:

• Manage enterprise storage platforms including Pure Storage, Nimble Storage, and NetApp arrays, responsible for provisioning, performance monitoring, snapshot management, and capacity planning; extend storage management to cloud-native solutions including AWS S3, EBS, and EFS, Azure Blob Storage, Azure Files, and OCI Object and Block Storage.

Identity & Access Management:

• Administer Microsoft Active Directory (Entra ID/Azure AD), DNS, DHCP, and Group Policy across the enterprise environment; integrate identity and access management with AWS IAM, Azure RBAC, and OCI IAM, including federated SSO, service principals, and privileged access management across cloud platforms.

Audit & SOX Compliance:

• Lead and support IT audit and SOX compliance activities including GCC and application controls; maintain accurate infrastructure documentation, asset inventories, and evidence packages for internal and external auditors, including cloud configuration baselines, access reviews, and compliance posture reporting using tools such as AWS Security Hub, Microsoft Defender for Cloud, and OCI Cloud Guard.
