Sr. Network/Systems Engineer

Aegis IT Solutions is growing its footprint in New England, and we need a senior engineer who can support field techs, project techs, and other roles with skillful automations and higher-complexity problem solving — someone client's trust on sight and junior engineers learn from every day.

About Aegis IT Solutions

Aegis IT Solutions is a managed service provider supporting small and mid-sized businesses. We handle the network, server, cloud, and security work our clients can't staff themselves, acting as their outsourced IT department. Our clients stay with us because our engineers show up knowing their environment, not just their ticket.

About the Role

You'll be an engineer other technicians escalate to when something doesn't add up, the one leading infrastructure projects from scoping through cutover, and a familiar face at our key client sites across the region. You'll split your time between our office, client locations, and remote support — with the judgment to know when each is needed.

What You'll Do

● Own escalations from Tier 1/2 support — diagnose and resolve the network, server, and infrastructure issues that stump the rest of the team

● Design and lead infrastructure projects for clients: network builds, server migrations, cloud transitions, and security hardening

● Serve as the primary technical point of contact for a portfolio of client accounts, translating business needs into IT solutions

● Maintain and improve network environments with diverse hardware ecosystems — routing, switching, firewalls, IoT and wireless — across multiple client sites.

● Mentor Tier 1/2 engineers and technicians, building the bench strength of the team

● Keep documentation, network diagrams, and SOPs current for every environment you touch

● Participate in an on-call rotation for after-hours critical incidents

What We're Looking For

Required

● 7+ years of hands-on IT infrastructure or network engineering experience

● 2+ years supporting multiple clients or business units in an MSP or similar environment

● Working knowledge and experience with Windows Server, Active Directory, and Microsoft 365 / Azure administration

● Demonstratable cybersecurity awareness, and the ability to work within written company policies and procedures

● Hands-on experience configuring and troubleshooting Cisco Meraki and Fortinet FortiGate environments — switching, firewalls, SD-WAN, and VPN

● Experience with virtualization platforms (VMware or Hyper-V) and network storage systems

● A valid driver's license and willingness to travel to client sites across Massachusetts and Northern Connecticut

Preferred

● Experience with AWS, in addition to Azure/Microsoft 365

● NSE (Fortinet) or Meraki/Cisco certification (CCNA/CCNP)

● Security certifications (Security+, CISSP, or similar)

● Experience with PSA/RMM tooling (HaloPSA, NinjaRMM preferred)

● PowerShell or other scripting experience for automation

Pay: $100,000.00 - $120,000.00 per year

Benefits

• 401(k)
• Flexible schedule
• Paid time off
