Pogue Construction•McKinney, TX

About The Position

Pogue Construction is modernizing its technology foundation as our AI team builds and replaces core company software. We are hiring a hands-on engineer to help build and secure the infrastructure this work will grow on – someone who wants to help shape a maturing environment, not simply keep the lights on. The IT Systems Engineer & Security Specialist builds, configures, maintains, and improves Pogue’s core technology environment – servers, cloud, identity, network, and endpoints – to defined standards, while contributing strong, practical security skills across the estate. Reporting to the Director of Infrastructure & Security, this engineer keeps systems reliable, secure, and well-documented across offices and jobsites. On security, this engineer is Pogue’s hands-on specialist during an interim period – standing up and strengthening the security posture and risk-reduction work now, with strategic risk ownership transitioning to a dedicated Security Owner as that role is filled. The focus is on implementing and maintaining strong security controls, not carrying sole responsibility for security strategy or risk acceptance.

7+ years of systems/infrastructure engineering in a multi-site Microsoft environment spanning on-premises and cloud
Deep Microsoft Azure and Entra ID experience
3+ years of hands-on security operations
7+ years as a systems / infrastructure engineer building and maintaining multi-site Microsoft environments across on-premises and cloud.
Deep, hands-on expertise with Microsoft Azure and Entra ID, plus Microsoft 365 and Intune.
Strong skills across servers, virtualization, storage, and network (routing/switching, firewalls, VLANs, VPN).
3+ years of practical security experience: least privilege, MFA/Conditional Access, vulnerability remediation, and incident-response support, with working familiarity of a control framework (NIST CSF 2.0 or CIS).

Responsibilities

Build, configure, maintain, and improve servers, virtualization, storage, cloud (Azure), identity (Entra ID), Intune, and network to defined standards.
Monitor infrastructure health and resolve performance, availability, and capacity issues.
Execute infrastructure changes through change management, with rollback paths and clear documentation.
Identify technical debt and single points of failure; contribute to modernization and automation.
Help stand up and strengthen Pogue’s security posture and risk-reduction work – applying least privilege, segmentation, hardening, logging, and identity-first configuration in daily engineering – until a dedicated Security Owner is hired.
Remediate open Microsoft 365 baseline controls and support progress toward NIST CSF 2.0.
Operate and maintain the security stack – Defendify, CrowdStrike, Netwrix, Microsoft Defender/Purview, MFA, Conditional Access.
Perform vulnerability remediation across the environment and support incident response – containment, evidence preservation, and post-incident follow-up.

Maintain accurate documentation – configurations, runbooks, diagrams, and dependency notes.
Contribute to infrastructure, cloud, identity, and network standards within architecture guardrails set by the Director.
Coordinate technical cases with infrastructure and security vendors; validate recommendations before implementation.
Support backup, DR, and resilience execution against defined RTO/RPO targets.
Serve as the Tier 3 escalation point for complex server, identity, M365, cloud, network, and infrastructure problems.
Provide technical guidance to helpdesk, endpoint, and field support staff; convert recurring issues into standards and reduce repeat escalations.
