Senior Infrastructure Engineer

Role Summary

We’re seeking a Senior Network / Infrastructure Engineer with strong experience 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.

Key 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.

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.

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.

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
