Full Job Description

Description:

As an onsite Tier 3 Senior Systems & Network Engineer, you will serve as the highest level of technical escalation within the IT department. This role carries a dual mandate: maintaining the reliability, performance, and security of existing infrastructure, and engineering new solutions that support business growth and modernization.

You will handle complex technical issues that cannot be resolved by Tier 1 or Tier 2 support while simultaneously architecting and deploying next-generation infrastructure. Networking is a core competency for this role — you will own and evolve the organization’s network environment alongside Windows Server, Microsoft Azure, Intune, infrastructure monitoring platforms, and line-of-business application maintenance.

Responsibilities

Act as the highest escalation point for infrastructure, system, and network issues
Maintain, support, and continuously improve existing server, network, and endpoint infrastructure
Engineer and deploy new infrastructure solutions from design through implementation, aligned with business growth and modernization goals
Own and evolve the organization’s network infrastructure — including firewalls, routers, switches, VLANs, and VPNs — both maintaining current environments and designing improvements
Troubleshoot and resolve complex technical issues across servers, endpoints, and network systems
Manage and maintain Windows Server environments and Active Directory infrastructure
Monitor system and network performance using platforms such as Zabbix; deploy and manage infrastructure monitoring and alerting solutions
Architect and lead deployment of new infrastructure solutions aligned with business growth and modernization goals
Own and administer Microsoft Azure and hybrid cloud environments
Deploy, manage, and maintain endpoint environments using Microsoft Intune
Support and maintain line-of-business applications, including patching, updates, and vendor coordination
Support virtualization environments and ensure system availability and performance
Assist with infrastructure projects, including migrations, deployments, and integrations
Provide technical guidance and escalation support to Tier 1 and Tier 2 teams
Maintain technical documentation, network diagrams, and system procedures
Ensure security best practices, patch management, and system hardening standards are followed
Evaluate and recommend new technologies to improve infrastructure efficiency and reliability

Requirements:

Bachelor’s degree in Information Technology, Computer Science, or related field preferred
5+ years of experience in IT infrastructure, systems administration, or network engineering
Strong experience with Windows Server (2016/2019/2022) environments
Advanced knowledge of Active Directory, DNS, DHCP, and Group Policy
Strong networking experience including switches, routers, VLANs, VPNs, and firewalls – required
Experience troubleshooting both server and network infrastructure issues
Experience with virtualization (Hyper-V or VMware)
Hands-on experience with Microsoft Azure and hybrid cloud environments – required
Proficiency with endpoint management tools, specifically Microsoft Intune – required
Experience with infrastructure monitoring platforms such as Zabbix, or demonstrated ability and willingness to learn
Experience supporting and maintaining line-of-business applications, including patching and vendor coordination
Strong problem-solving and analytical skills
Ability to mentor and support Tier 1 and Tier 2 technicians
Certifications such as CCNA, Microsoft certifications (Azure, Intune), or equivalent preferred

Benefits: AFIC offers a competitive salary and a comprehensive benefits package to support you

Competitive Salary: Rewarding your expertise and experience
Financial Security: 401K with up to a 6% company match
Health & Wellness: Choice of Blue Cross Blue Shield PPO, HMO, or HSA plans, Dental and vision coverage, Access to telemedicine services
