Senior Infrastructure Engineer

Job Description

Role Summary

\n

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

\n

deploying, and supporting enterprise networks and modern infrastructure platforms. This hands-on

\n

role focuses on secure data transfer, infrastructure optimization, and day-to-day management of

\n

networking hardware, virtualization, and cloud workloads, with a strong bias toward automation

\n

and operational rigor.

\n

Key Responsibilities

\n

Infrastructure Management

\n

 Own day-to-day operations of the VMware environment (vSphere/ESX/ESXi): lifecycle

\n

management, capacity, performance tuning, patching, upgrades, backup/DR coordination,

\n

and incident response.

\n

 Partner on the virtualization roadmap, including planning and execution for migration from

\n

VMware to Nutanix (or Nutanix-based platforms), minimizing downtime and risk.

\n

 Operate and optimize storage and compute platforms (e.g., Cisco UCS, SAN/NAS such as

\n

NetApp FAS/AFF, FlexPod), including performance troubleshooting and resilience planning.

\n

Cloud & Platform Operations

\n

 Manage and optimize Microsoft Azure workloads: networking, compute, storage, security

\n

controls, cost optimization, and operational monitoring.

\n

 Operate Kubernetes environments (cluster upgrades, reliability, networking, ingress,

\n

policy, and workload troubleshooting).

\n

 Build, deploy, and support Docker containerized applications and supporting infrastructure

\n

(registries, image hygiene, runtime security, scaling).

\n

 Implement and maintain load balancing solutions (L4/L7), including TLS configuration and

\n

operational monitoring.

\n

Network Engineering & Communications

\n

 Design, implement, and support enterprise data/voice/video networks across

\n

LAN/WAN/Wi-Fi.

\n

 Configure and support routing/switching and core network services (TCP/IP, BGP, OSPF,

\n

VLANs, QoS, DHCP/DNS).

\n

 Administer and harden firewalls/VPNs (SonicWall, Cisco ASA, Palo Alto) and support

\n

secure remote access patterns.

\n

Security, Secure Transfers, and Compliance Support

\n

 Maintain secure internal and external data transfer mechanisms (e.g., SFTP/managed file

\n

transfer), including certificate/keys, access controls, and auditing.

\n

 Support vulnerability remediation, security hardening, and practical control

\n

implementation aligned to customer/security expectations (e.g., PCI/SOC-related controls

\n

where applicable).

\n

 Own SSL/TLS certificate lifecycle management across infrastructure components.

\n

Operational Excellence & Automation

\n

 Build repeatable, automated operations (Infrastructure-as-Code and configuration

\n

management preferred), reducing manual work and increasing reliability.

\n

 Improve observability and troubleshooting practices (monitoring, alerting, packet capture,

\n

traffic analysis) and drive root-cause prevention.

\n

 Participate in on-call/after-hours support rotations as needed for high-priority incidents

\n

and maintenance windows.

\n

Collaboration

\n

 Collaborate across internal teams and external vendors/clients to plan changes, execute

\n

upgrades, resolve incidents, and document outcomes.

\n

 Create and maintain clear technical documentation (runbooks, diagrams, standards) to

\n

improve operational consistency and knowledge sharing.

\n

Required Qualifications

\n

 5+ years in a senior network/infrastructure engineering role supporting enterprise

\n

environments (hybrid datacenter + cloud).

\n

 Strong, hands-on experience with Kubernetes, VMware (vSphere/ESX/ESXi), and Microsoft

\n

Azure (these are must-haves).

\n

 Proven experience designing/supporting enterprise networks: LAN/WAN/Wi-Fi,

\n

routing/switching, VPNs, QoS, and troubleshooting (packet capture/traffic analysis).

\n

 Firewall administration experience with one or more of SonicWall, Cisco ASA, and Palo Alto

\n

(policy, VPN, logging/triage).

\n

 Experience with virtualization operations and performance tuning (compute, storage,

\n

networking).

\n

 Windows Server administration experience (including legacy environments as needed),

\n

Active Directory, Group Policy, and Exchange in enterprise contexts.

\n

 Working knowledge supporting SQL Server environments (AlwaysOn preferred).

\n

 Strong operational habits: change management discipline, incident response,

\n

documentation, and clear communication.

\n

Preferred Qualifications

\n

 Bachelor’s degree in a related field and significant datacenter operations experience.

\n

 Certifications such as CCNA/CCNP, VCP, Nutanix (NCP), Azure (AZ-104/AZ-305), Security+,

\n

or equivalent experience.

\n

 Experience with Cisco UCS, NetApp FAS/AFF, and FlexPod architectures in production

\n

environments.

\n

 Familiarity with IIS/Tomcat administration and email security tooling (e.g., SpamTitan).

\n

 Experience with tools such as Jira, Kace, SolarWinds, PRTG, Cerberus SFTP, Zerto, Trend

\n

Micro, WSUS, and related monitoring/endpoint/security platforms.

\n

Compensation & Benefits

\n
