TECHNICAL LEADERSHIP & ESCALATION:

• Serve as the primary escalation point for complex network incidents, outages, and performance issues owing problems through to resolution with clear communication to stakeholders

• Provide expert guidance to internal engineers, MSP resources, and NOC personnel on architecture, troubleshooting methodology, and root cause analysis

• Lead post-incident reviews, drive root cause identification, and implement lasting remediations to prevent recurrence

• Evaluate complex vendor and MSP escalations; make technical decisions on design, tooling, and resolution approach

NETWORK ARCHITECTURE & DESIGN:

• Work with the Director of Network & Infrastructure to architect scalable, resilient, and secure network solutions across LAN, WAN, wireless, cloud, and building infrastructure

• Lead the design and evolution of network segmentation strategy including zero-trust principles, VRF separation, and secure OT/IT boundary enforcement

• Develop and maintain network infrastructure standards, reference architectures, and design patterns for consistent deployment across properties

• Evaluate emerging technologies and contribute to the long-term infrastructure roadmap, particularly around Palo Alto / Panorama, Aruba, and cloud connectivity platforms

NETWORK ENGINEERING & OPERATIONS:

• Design, deploy, and manage enterprise network infrastructure across BMS, IoT, Wi-Fi, PropTech, AV, security systems, corporate offices, and the Observatory

• Administer Palo Alto NGFWs via Panorama — policy management, threat prevention, VPN, NAT, and security profile lifecycle management

• Manage and optimize Aruba switching and wireless infrastructure including configuration, upgrades, RF planning, and troubleshooting via Aruba Central

• Own BGP, OSPF, VLANs, VPN, QoS, and DNS configurations across multi-site environments

• Manage WAN and ISP connectivity including failover design and carrier-level troubleshooting

• Support IoT and PropTech deployments in a secure manner with a focus on building systems, access control, and sustainability technology

SECURITY & COMPLIANCE:

• Lead network security posture improvements including firewall policy lifecycle, ACL governance, and vulnerability remediation

• Administer Zscaler ZIA and ZPA — URL filtering, SSL inspection, cloud firewall rules, and app connector management

• Manage Proofpoint email security platform including anti-spam, anti-phishing, encryption, and threat response policies

• Administer BitSight to track, triage, and coordinate remediation of external security posture findings

• Maintain PCI-DSS and SOX compliance through adherence to and enforcement of network policies and procedures

• Collaborate with the MSSP on security monitoring, threat analysis, and incident response

• Ensure timely application of patches, hotfixes, and firmware upgrades across all network equipment

IDENTITY, ACCESS & CLOUD:

• Administer Okta for SSO/SAML/OIDC, MFA enforcement, and user lifecycle management including SCIM provisioning and deprovisioning

• Manage Conditional Access Policies and integrate identity platforms with Palo Alto User-ID, Zscaler IdP federation, and Azure AD

• Design and manage Microsoft Azure cloud networking including hybrid connectivity, VNet architecture, NSGs, and Azure Firewall

• Support Microsoft 365 and Exchange Online from a network and connectivity perspective including split tunneling and optimization

• Support IAM and PAM platforms as they relate to network access control and privilege governance

PHYSICAL INFRASTRUCTURE & SYSTEMS:

• Manage physical server infrastructure, rack equipment installation, and data center operations including cabling, power, and cooling

• Administer building riser infrastructure and ensure secure integration of IT and OT devices on segregated network segments

• Support VMware vSphere virtual networking environments and server resource management

• Oversee SAN/NAS storage networking and business continuity / backup technologies

MONITORING, DOCUMENTATION & GOVERNANCE:

• Drive network monitoring strategy and tooling to ensure proactive alerting and performance trending across the full infrastructure estate

• Author and maintain high-quality documentation including topology diagrams, configuration baselines, SOPs, and runbooks

• Contribute to business continuity and disaster recovery procedures; develop, test, and maintain failover runbooks

• Adhere to change management and PMO best practices for all infrastructure changes; manage project milestones with clear stakeholder communication

• Complex escalations are resolved decisively and thoroughly, with clear communication throughout the team and Director trust this person to own the hardest problems

• Network architecture documentation, standards, and reference designs are developed and kept current, reducing reliance on tribal knowledge

• Security posture improves measurably: firewall policies are rationalized, vulnerabilities remediated on time, and segmentation consistently enforced

• Network stability and availability are maintained across all properties; incidents are detected proactively rather than reactively

• New technologies and architectural improvements are identified and brought forward with well-reasoned business cases

• Service Desk escalations are resolved efficiently with recurring patterns identified and addressed proactively

• 8–10 years of progressive, hands-on enterprise network engineering experience with demonstrated depth in complex, multi-site environments

• At least 3 years in a senior or lead capacity managing complex, multi-site infrastructure

• Proven experience serving as a technical escalation resource or informal architect on an infrastructure team

• Experience in Real Estate, Financial Services, or a similarly regulated industry preferred

• PCNSE (Palo Alto Networks Certified Network Security Engineer) strongly preferred; Panorama hands-on experience is a firm requirement

• Aruba/HPE (ACSA/ACCP), Zscaler (ZCCA-IA/PA), Azure (AZ-104), or Okta Certified Administrator are a plus

• CCNP Enterprise or equivalent routing/switching certification considered; demonstrated production depth matters most

• Associate's or Bachelor's Degree in Computer Science, Information Technology, or related field preferred; equivalent professional experience considered
