Senior IT Network & Systems Engineer
We are seeking a Senior IT Network & Systems Engineer with 10–12 years of progressive experience across systems engineering, networking, cloud administration, security, and technical team oversight. This role is ideal for a senior-level engineer who is still deeply hands-on but has also taken on leadership or light management responsibilities.
This position involves 70–75% hands-on technical engineering (helpdesk escalation, systems, networking, security, cloud) and 25–30% team leadership and management oversight (mentoring junior engineers, coordinating work, assisting with vendor management, and advising leadership on technical direction).
You will support a hybrid infrastructure environment that includes on-prem Active Directory integrated with Microsoft 365, AWS services, modern endpoint management, network security infrastructure, and enterprise SaaS applications.
Key Responsibilities:
- Cloud & Systems Engineering
- Architect, administer, and troubleshoot AWS cloud services (IAM, EC2, S3, VPC, monitoring).
- Manage hybrid Microsoft 365 and Active Directory services (Exchange Online, Teams, SharePoint permissions, Azure AD).

- Networking & Security
- Configure, maintain, and troubleshoot enterprise network components: switches, routers, firewalls (e.g., Fortinet, Cisco, Palo Alto), VPN, WLAN.
- Implement and manage security tools: endpoint protection, MFA, email security, vulnerability management, and security monitoring.
- Participate in incident response, root-cause analysis, and remediation efforts.
- Helpdesk & Escalation Support
- Serve as Tier 3 technical escalation for complex issues across systems, networking, and security.
- Maintain endpoint environment (Windows laptops/desktops, SaaS applications, patching, compliance).
- Oversee user lifecycle workflows and ensure provisioning standards across AD and Microsoft 365.
- Technical Projects & Architecture
- Lead implementation of IT infrastructure projects including migrations, upgrades, and new technology rollouts.
- Document systems, create runbooks, and improve operational processes and automation.
Management & Leadership (25–30%)
- Provide guidance, mentorship, and technical oversight to junior and mid-level IT staff.
- Coordinate daily workload, set priorities, and ensure timely delivery of IT services.
- Collaborate with leadership on technical strategy, budgeting, infrastructure planning, and vendor management.
- Maintain accountability for system uptime, security posture, and SLA performance.
- Assist in drafting IT policies, security standards, and operational documentation.
Qualifications:
- 10–12 years of hands-on experience in IT systems engineering, network engineering, and cloud administration.
- 4+ years of AWS experience
- Strong expertise with AWS, Microsoft 365, Active Directory, Windows Server, and modern endpoint management.
- Deep knowledge of networking fundamentals: firewalls, VPNs, switching, routing, and wireless networks.
- Strong background in IT security, including MFA, vulnerability scanning, endpoint protection, and patching.
- Experience acting as a technical lead or team supervisor (formal management experience is helpful but not required).
- Strong troubleshooting, analytical thinking, and ability to self-manage in high-paced environments.
- Experience with scripting or automation (PowerShell, Python, Bash) is preferred.
- Relevant certifications are a plus (AWS, CCNA/CCNP, Microsoft, Security+, etc.).
Benefits:
- Excellent benefits including Medical, Dental, Vision, and company-paid Life Insurance.
- Generous 401(k) with aggressive company match.
- Convenient location near Legacy West.
