This position is 100% Onsite in Charlotte, NC.

Requirements

5+ years in a senior network/infrastructure engineering role supporting enterprise environments (hybrid datacenter + cloud).
Strong, hands-on experience with Kubernetes, VMware (vSphere/ESX/ESXi), and Microsoft Azure (these are must-haves).
Proven experience designing/supporting enterprise networks: LAN/WAN/Wi-Fi, routing/switching, VPNs, QoS, and troubleshooting (packet capture/traffic analysis).
Firewall administration experience with one or more of SonicWall, Cisco ASA, and Palo Alto (policy, VPN, logging/triage).
Experience with virtualization operations and performance tuning (compute, storage, networking).
Windows Server administration experience (including legacy environments as needed), Active Directory, Group Policy, and Exchange in enterprise contexts.
Working knowledge supporting SQL Server environments (AlwaysOn preferred).
Strong operational habits: change management discipline, incident response, documentation, and clear communication.

Nice To Haves

Bachelor’s degree in a related field and significant datacenter operations experience.
Certifications such as CCNA/CCNP, VCP, Nutanix (NCP), Azure (AZ-104/AZ-305), Security+, or equivalent experience.
Experience with Cisco UCS, NetApp FAS/AFF, and FlexPod architectures in production environments.
Familiarity with IIS/Tomcat administration and email security tooling (e.g., SpamTitan).
Experience with tools such as Jira, Kace, SolarWinds, PRTG, Cerberus SFTP, Zerto, Trend Micro, WSUS, and related monitoring/endpoint/security platforms.

Responsibilities

Own day-to-day operations of the VMware environment (vSphere/ESX/ESXi): lifecycle management, capacity, performance tuning, patching, upgrades, backup/DR coordination, and incident response.
Partner on the virtualization roadmap, including planning and execution for migration from VMware to Nutanix (or Nutanix-based platforms), minimizing downtime and risk.
Operate and optimize storage and compute platforms (e.g., Cisco UCS, SAN/NAS such as NetApp FAS/AFF, FlexPod), including performance troubleshooting and resilience planning.
Manage and optimize Microsoft Azure workloads: networking, compute, storage, security controls, cost optimization, and operational monitoring.
Operate Kubernetes environments (cluster upgrades, reliability, networking, ingress, policy, and workload troubleshooting).
Build, deploy, and support Docker containerized applications and supporting infrastructure (registries, image hygiene, runtime security, scaling).
Implement and maintain load balancing solutions (L4/L7), including TLS configuration and operational monitoring.
Design, implement, and support enterprise data/voice/video networks across LAN/WAN/Wi-Fi.
Configure and support routing/switching and core network services (TCP/IP, BGP, OSPF, VLANs, QoS, DHCP/DNS).
Administer and harden firewalls/VPNs (SonicWall, Cisco ASA, Palo Alto) and support secure remote access patterns.
Maintain secure internal and external data transfer mechanisms (e.g., SFTP/managed file transfer), including certificate/keys, access controls, and auditing.
Support vulnerability remediation, security hardening, and practical control implementation aligned to customer/security expectations (e.g., PCI/SOC-related controls where applicable).
Own SSL/TLS certificate lifecycle management across infrastructure components.
Build repeatable, automated operations (Infrastructure-as-Code and configuration management preferred), reducing manual work and increasing reliability.
Improve observability and troubleshooting practices (monitoring, alerting, packet capture, traffic analysis) and drive root-cause prevention.
Participate in on-call/after-hours support rotations as needed for high-priority incidents and maintenance windows.
Collaborate across internal teams and external vendors/clients to plan changes, execute upgrades, resolve incidents, and document outcomes.
Create and maintain clear technical documentation (runbooks, diagrams, standards) to improve operational consistency and knowledge sharing.
