Full Job Description

About the Role

We’re looking for a Network Support Engineer II who can handle Level 1-3 support tickets, escalations, and troubleshooting across network, cloud, and security environments.

This role is primarily support-focused, but requires the ability to:

Understand how systems are designed
Make sound technical decisions during troubleshooting
Maintain compliance with security frameworks (CMMC, NIST)

This is not entry-level support. You will be expected to resolve complex issues, communicate directly with clients, and ensure all work is fully documented and audit-ready.

What You’ll Do

Advanced Support & Troubleshooting

Resolve Level 1, 2 and Level 3 support tickets across:
Networking (connectivity, routing, VPNs, VLANs)
Microsoft 365 environments
Azure / cloud systems (basic to intermediate)
Identity & access issues (Entra ID, MFA, permissions)
Troubleshoot issues end-to-end and implement permanent fixes, not workarounds
Act as an escalation point for Level 1 technicians

Client Communication

Communicate directly with clients via phone and email
Clearly explain issues, resolutions, and timelines
Set expectations and maintain professionalism at all times

Ticketing & Documentation (Critical)

Fully document all work performed in tickets, including:
Root cause
Troubleshooting steps
Resolution details
Ensure documentation is clear, complete, and audit-ready
Follow and contribute to SOPs and runbooks
Maintain accurate system and configuration documentation

Compliance & Security Awareness

Troubleshoot and resolve issues while maintaining compliance with:
CMMC 2
NIST 800-171
Follow secure practices (least privilege, access control, etc.)
Understand how changes impact compliance and security posture

Light Engineering / Implementation

Assist with small implementations and changes, such as:
Firewall rule updates
User access configurations
Network adjustments
Follow established standards when making changes
Escalate design decisions to senior engineers when needed

What You Bring

Required

5-7 years experience in IT support, networking, or MSP environments
Strong troubleshooting skills across:
Networking (TCP/IP, DNS, DHCP, VPNs)
Microsoft 365
Basic Azure / cloud environments
Experience handling escalated or complex support issues
Strong written and verbal communication skills
High attention to detail in documentation

Preferred

Experience in MSP environments
Exposure to compliance frameworks (CMMC, NIST, HIPAA, etc.)
Experience with firewalls (Fortinet, Meraki, SonicWall)
Certifications:
Network+, Security+, or equivalent
Microsoft certifications

What Success Looks Like

You consistently resolve complex tickets without escalation
Your tickets are fully documented and audit-ready every time
Clients trust your communication and clarity
You follow processes but also understand why they exist
You escalate appropriately

What This Role Is NOT

Not entry-level / help desk only
Not a pure architect or design-heavy engineering role
Not a “close tickets fast” position — quality and documentation matter as much as speed

Why Join Us

Work in a compliance-driven, security-focused environment
Gain exposure to regulated environments (CMMC / DIB clients)
Clear path to Lead Network Engineer or Cybersecurity roles
High accountability, high growth environment

Additional Requirements

Ability to pass background and drug check
Comfortable working with regulated and sensitive environments
Strong adherence to process, documentation, and security standards

Pay: From $75,000.00 per year

Benefits:

401(k) matching
Dental insurance
Health insurance
Life insurance
Paid time off
Vision insurance
