Role Overview

We are seeking an IT Infrastructure Security Operations Engineer to own the day-to-day operational security posture of our enterprise infrastructure. This role is focused on Continuous Diagnostics and Mitigation (CDM) — the ongoing work of monitoring infrastructure health, enforcing configuration baselines, managing patching cadence, coordinating vulnerability remediation, and ensuring our environments remain hardened between audit cycles. This is an operational execution role, not a governance or audit role. The Infrastructure Security Operations Engineer works within IT Infrastructure Operations and complements our Cybersecurity function, which owns governance, audit, and security assessment. Together, the two functions maintain a healthy separation of duties — Cybersecurity assesses, Infrastructure Operations remediates and hardens. The ideal candidate brings deep hands-on experience across both Windows and Linux environments, a strong understanding of security operations at the infrastructure level, and the discipline to maintain continuous hygiene rather than reactive fixes.

Responsibilities

• Own and execute the Continuous Diagnostics and Mitigation (CDM) program for enterprise infrastructure, including both Windows and Linux environments.
• Manage and enforce patch management cadence across all infrastructure systems, tracking compliance and driving remediation of gaps.
• Establish and maintain configuration baselines for servers, endpoints, and network-adjacent systems; monitor for drift and enforce corrections.
• Coordinate vulnerability remediation by triaging scan results, prioritizing findings, and working with Systems and Network teams to implement fixes within defined SLAs.
• Conduct and manage access reviews, ensuring appropriate permissions, removing stale accounts, and documenting findings.
• Continuously monitor infrastructure security posture using available tools (SIEM, endpoint protection, vulnerability scanners) and escalate anomalies as appropriate.
• Prepare and maintain operational evidence to support internal and external audits, ensuring Infrastructure Operations can demonstrate compliance with frameworks such as CMMC, SOC2, and ISO 27001.
• Create, update, and maintain detailed documentation for security operations processes, controls, and remediation activities.
• Collaborate with the Cybersecurity team to align operational execution with governance requirements, audit findings, and evolving security standards.
• Collaborate with Systems Administrators and Systems Engineers to ensure security practices are integrated into daily infrastructure operations rather than treated as separate workstreams.
• Identify opportunities to automate and improve security operations workflows, reducing manual effort and increasing consistency.
• Provide Tier 2/3 escalation support for security-related infrastructure issues and end user support requests that exceed Help Desk capabilities.
• Stay current with evolving threats, vulnerabilities, and industry best practices to continuously improve the organization's security posture.
