This hands-on role is responsible for secure and reliable connectivity, core infrastructure, security operations, and cloud security. The successful candidate will bring strong network and cybersecurity fundamentals together with practical Azure infrastructure and security experience. The engineer will work directly across on-premises and cloud environments to investigate alerts, troubleshoot complex issues, identify gaps in tooling, architecture, setup, configuration, monitoring, and processes, and implement or coordinate sustainable fixes. The role calls for a SOC-oriented mindset that is alert, curious, proactive, and accountable, along with an outgoing and enthusiastic approach to collaboration. This is not an Azure application development or cloud architecture role. It is a network and security engineering role with dedicated responsibility for strengthening cloud as part of AIR Communities' broader hybrid environment. Where You Will Work This position is based at our corporate office in the Denver Tech Center. The role is expected to work in the office 4 to 5 days per week, based on business and team needs., * Engineer, maintain, and secure network infrastructure across corporate offices, property sites, on-premises environments, and cloud-connected networks, including LAN, WAN, WLAN, VPN, SD-WAN, and cloud connectivity. * Configure and support routers, switches, wireless access points, firewalls, load balancers, VPNs, DNS, DHCP, network segmentation, and secure remote connectivity across distributed locations. * Support cloud networking capabilities, including virtual networks, subnets, Network Security Groups, route tables, private endpoints, VPN or ExpressRoute connectivity, cloud Firewall, Application Gateway, and network monitoring. * Lead or contribute to network upgrades, migrations, troubleshooting, performance optimization, and resiliency improvements across on-premises and cloud-connected environments. * Maintain high availability, disaster-recovery readiness, secure connectivity, and consistent network standards across the hybrid environment. * Diagnose complex routing, switching, firewall, wireless, DNS, identity, and hybrid-cloud connectivity issues. IT Security and Cloud Security * Implement and maintain security controls and operational practices across network, endpoint, identity, server, application, SaaS, and cloud environments. * Monitor, investigate, prioritize, and respond to security incidents, vulnerabilities, anomalous activity, and emerging threats using a SOC-oriented approach. * Operate and improve security technologies such as firewalls, IDS/IPS, endpoint protection, EDR/XDR, vulnerability-management, SIEM/SOAR, CSPM, SSPM, and MDR platforms. * Use cloud-native security posture, threat detection, policy, identity and access management, privileged access, secrets management, and logging tools to identify and remediate cloud security and configuration gaps. * Validate findings, assess risk and business impact, and address gaps in tooling, configuration, logging, monitoring, access, and operational processes across on-premises and cloud environments. * Tune detections, reduce false positives, improve alert coverage, incorporate threat intelligence, and develop practical countermeasures. * Support risk assessments, vulnerability reviews, penetration-test remediation, compliance reviews, and control validation across infrastructure, applications, containers, and cloud workloads. * Partner with application, data, and business teams to support secure deployments and maintain clear procedures, investigation records, remediation plans, and audit evidence. Core Infrastructure Management and Monitoring * Administer, maintain, and secure physical and virtual infrastructure supporting enterprise operations across on-premises and cloud environments. * Support Windows and Linux servers, Active Directory, IDP, DNS, DHCP, certificates, file services, virtualization, storage, backup, and identity-related services. * Maintain infrastructure performance, patching, hardening, backup, recovery, capacity, and availability standards. * Improve monitoring and centralized logging across networks, servers, cloud resources, applications, and security controls. * Identify monitoring gaps, unhealthy configurations, control failures, capacity concerns, and recurring incidents, and implement or coordinate durable fixes. * Collaborate with vendors and internal teams to improve monitoring, incident escalation, and operational support. Leadership, Collaboration, and Mindset * Bring an alert, proactive, hands-on, and ownership-oriented approach to network, infrastructure, and security operations. * Build productive relationships with technical teams, business partners, vendors, and leadership through an outgoing, enthusiastic, and service-oriented approach. * Communicate risks and technical findings clearly, recommend practical solutions, and follow issues through resolution. * Mentor less-experienced engineers and contribute to clear documentation, repeatable processes, and team development. * Advise leadership on relevant threats, control gaps, technology trends, and priorities across the hybrid environment. * Lead or contribute to cross-functional initiatives that improve network reliability, infrastructure resilience, cloud security, detection capability, and operational maturity.
