Network Engineer (Mid-Level | Cloud-Exposed | Ticket-Driving)

Salary: Up to $100,000/year

Employment Type: Full-Time | Exempt | Salaried

Schedule: Monday–Friday, 8:00 AM–5:00 PM (occasional after-hours as needed)

Position Overview

Tier4Group is seeking a proactive, hands-on Network Engineer who will actively drive, own, and close technical tickets while serving as a key technical bridge between the Senior Network Engineer and Tier 1 NOC team.

This is a true “middle-ground” engineer role — ideal for someone operating at a Tier 3 support level with approximately 3+ years of networking experience and working exposure to cloud environments (AWS and/or Azure). The ideal candidate is technically strong, operationally driven, and comfortable working in multi-tenant environments.

This role requires someone who does not wait for direction but actively pushes issues toward resolution, improves processes, and helps elevate the overall support function.

What You’ll Do

Network Operations & Support

• Monitor network availability, performance, and reliability across environments.
• Proactively identify, troubleshoot, and resolve issues to ensure maximum uptime.
• Take ownership of escalated tickets and actively drive them to closure.
• Serve as the escalation point between Tier 1 NOC and Senior Network Engineering.
• Perform root cause analysis, document findings, and recommend long-term improvements.
• Support mission-critical systems in multi-tenant environments.

Infrastructure Implementation & Maintenance

• Deploy, configure, and maintain routers, switches, firewalls, wireless access points, and related infrastructure.
• Work with hardware platforms such as SonicWall, Cambium, UniFi, Meraki, Fortinet, WatchGuard, or similar vendors.
• Maintain secure, high-availability network environments.
• Ensure proper documentation and diagram updates aligned with best practices.

Cloud & Hybrid Networking

• Support hybrid networking environments with exposure to AWS and/or Azure.
• Understand cloud networking fundamentals including:
• Virtual networks (VPC/VNet)
• Subnetting and routing
• VPN connectivity
• Security groups and firewall policies
• Assist in troubleshooting connectivity between on-prem and cloud environments.
• No specific cloud platform is required, but working familiarity with cloud networking concepts is essential.

Security & Best Practices

• Implement and support network security controls to protect systems and data.
• Follow and help refine network standards, policies, and operational procedures.
• Utilize monitoring and troubleshooting tools such as Auvik, Wireshark, SolarWinds, or similar platforms.

Communication & Collaboration

• Communicate clearly with management regarding incidents, risks, and performance.
• Provide technical guidance to internal teams and end users.
• Act as a stabilizing technical buffer between leadership and frontline support.
• Help mentor and elevate Tier 1 resources where appropriate.

What You Bring

• ~3+ years of hands-on network engineering or advanced network support experience.
• Strong working knowledge of:
• TCP/IP
• DNS
• DHCP
• VLANs
• Routing & switching fundamentals
• Experience in multi-tenant or managed environments.
• Exposure to AWS and/or Azure networking concepts.
• Strong troubleshooting mindset and ability to independently drive issues to resolution.
• Experience with network monitoring and packet analysis tools.
• Solid understanding of network security best practices.
• Ability to balance independent ownership with collaborative teamwork.
• Strong documentation and communication skills.

Preferred Qualifications

• Bachelor’s degree in Computer Science, Information Technology, or related field.
• Industry certifications such as CompTIA Network+, Cisco CCNA, or equivalent.
• Experience operating in an MSP, NOC, or hybrid cloud environment.

Why This Role Matters

This role fills a critical operational gap. We are not seeking an entry-level NOC technician or a senior architect — we need a technically capable engineer who:

• Takes initiative
• Owns escalations
• Pushes tickets to closure
• Improves stability
• Supports cloud-connected environments
• Strengthens the bridge between frontline support and senior engineering

If you enjoy solving real infrastructure problems, stabilizing environments, and being the engineer others rely on to get things done — this is the role for you.
