Full Job Description

About the Role:

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:

Hands-On Engineering (70–75%)

· 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).

· Maintain Windows servers, patching, backups, disaster recovery procedures, and monitoring systems.

· 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.
