Senior Infrastructure Engineer

Key Responsibilities: Infrastructure Management Own day-to-day operations of the VMware environment (vSphere/ESX/ESXi): lifecyclemanagement, capacity, performance tuning, patching, upgrades, backup/DR coordination, and incident response. Partner on the virtualization roadmap, including planning and execution for migration fromVMware to Nutanix (or Nutanix-based platforms), minimizing downtime and risk. Operate and optimize storage and compute platforms (e.g., Cisco UCS, SAN/NAS such asNetApp FAS/AFF, FlexPod), including performance troubleshooting and resilience planning. Cloud & Platform Operations Manage and optimize Microsoft Azure workloads: networking, compute, storage, securitycontrols, 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 andoperational monitoring. Network Engineering & Communications Design, implement, and support enterprise data/voice/video networks acrossLAN/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 supportsecure remote access patterns. Security, Secure Transfers, and Compliance Support Maintain secure internal and external data transfer mechanisms (e.g., SFTP/managed filetransfer), including certificate/keys, access controls, and auditing. Support vulnerability remediation, security hardening, and practical controlimplementation aligned to customer/security expectations (e.g., PCI/SOC-related controlswhere applicable). Own SSL/TLS certificate lifecycle management across infrastructure components. Operational Excellence & Automation Build repeatable, automated operations (Infrastructure-as-Code and configurationmanagement 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 incidentsand maintenance windows. Collaboration Collaborate across internal teams and external vendors/clients to plan changes, executeupgrades, resolve incidents, and document outcomes. Create and maintain clear technical documentation (runbooks, diagrams, standards) toimprove operational consistency and knowledge sharing. Required Qualifications 5+ years in a senior network/infrastructure engineering role supporting enterpriseenvironments (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. 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 productionenvironments. Familiarity with IIS/Tomcat administration and email security tooling (e.g., SpamTitan). Experience with tools such as Jira, Kace, SolarWinds, PRTG, Cerberus SFTP, Zerto, TrendMicro, WSUS, and related monitoring/endpoint/security platforms. Compensation & Benefits Competitive salary commensurate with experience and qualifications. Comprehensive health, dental, and vision insurance. Paid time off and holidays. Retirement savings plan options. Opportunities for career advancement and professional growth
