• Develop and maintain network standards, diagrams, implementation plans, and support documentation.

Cybersecurity-Focused Network Engineering

• Engineer and enforce secure network controls including ACLs, VPNs, firewall policies, segmentation, secure remote access, and authentication controls.
• Harden network infrastructure and partner with security teams on vulnerability remediation, risk reduction, and control improvements.
• Support Zero Trust, attack surface reduction, and network security initiatives aligned to broader cyber strategy.
• Analyze and remediate security gaps affecting network devices, connectivity, and edge security platforms.

Palo Alto and Meraki Administration/Engineering

• Design, deploy, and manage Palo Alto firewalls, security policies, NAT, VPNs, threat prevention features, and related security services.
• Configure and support Cisco Meraki switches, wireless, routing, and site-to-site connectivity solutions.
• Standardize firewall and network security configurations to improve reliability, visibility, and control effectiveness.
• Troubleshoot complex connectivity and security issues across Palo Alto, Meraki, and adjacent infrastructure platforms.

Routing, Switching and Core Infrastructure

• Configure and support dynamic routing protocols such as BGP, OSPF, and related Layer 2/Layer 3 services.
• Manage switching, VLANs, wireless SSIDs, RADIUS-based authentication, subnetting, GRE, and secure inter-site connectivity.
• Support integration with core infrastructure services such as Active Directory, DNS, DHCP, PKI, and virtualization platforms where applicable.
• Perform advanced troubleshooting across network, firewall, system, and application layers.

Compliance, Audit and Governance

• Ensure network engineering practices align with internal security standards and external compliance requirements.
• Support audits, risk assessments, evidence gathering, remediation tracking, and control validation activities.
• Contribute to initiatives aligned with frameworks and regulatory standards such as NIST, HIPAA, PCI-DSS, SOX, and ISO 27001 as applicable to the environment.
• Maintain documentation and operational practices that support secure, auditable, and compliant network operations.

Collaboration and Leadership

• Act as a senior technical resource for infrastructure, security, cloud, and support teams.
• Mentor junior engineers and provide technical guidance on network and security best practices.
• Lead troubleshooting efforts for escalated incidents and drive root cause analysis and corrective action planning.
• Communicate technical risks, recommendations, and architecture decisions clearly to stakeholders.

Work Experience and Required Qualifications:

• 8+ years of progressive experience in network engineering, network security engineering, or infrastructure engineering roles.
• Advanced hands-on experience with enterprise routing, switching, firewalls, VPNs, and wireless networking.
