Senior Network/Infrastructure Engineer, Onsite in Charlotte, NC

We are seeking a Senior Network/Infrastructure Engineer with strong experience in designing, deploying, and supporting enterprise networks and modern infrastructure platforms. This hands-on role focuses on secure data transfer, infrastructure optimization, and day-to-day management of networking hardware, virtualization, and cloud workloads, with a strong bias toward automation and operational rigor. This position is 100% Onsite in Charlotte, NC.

Senior Network/Infrastructure Engineer Responsibilities:

Infrastructure Management

- 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.

Cloud & Platform Operations

- 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.

Network Engineering & Communications

- 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.

Security, Secure Transfers, and Compliance Support

- 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.

Operational Excellence & Automation

- 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.

Collaboration

- 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.

Qualifications

Senior Network/Infrastructure Engineer Required Qualifications:

- 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.

Senior Network/Infrastructure Engineer Preferred Qualifications:

- 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.

Benefits include medical insurance, Dental, Vision, Savings Plan Options, PTO, etc.
