The environment is security-first, requiring strong attention to detail, operational discipline, and a proactive approach to risk mitigation. You will work across identity, endpoint, and cloud security domains while enabling audit readiness and continuous compliance. This is a highly collaborative role supporting both engineering teams and governance stakeholders in maintaining resilient, compliant systems at scale.

• Design, implement, and maintain secure infrastructure across hybrid environments, ensuring alignment with compliance standards such as NIST SP 800-171 and CMMC requirements
• Manage identity and access solutions, including IAM/IGA frameworks, PKI architecture, and certificate lifecycle management
• Administer and secure cloud and endpoint environments using Microsoft Intune and Azure services
• Support architecture, governance, and integration of hybrid identity systems using Microsoft Entra ID and Active Directory
• Lead system hardening initiatives, including patching, vulnerability remediation, GPO management, and secure configuration baselines
• Ensure continuous compliance readiness by supporting audits, evidence collection, and control implementation activities
• Serve as a Level 3 escalation point for complex infrastructure and security incidents
• Mentor junior engineers and contribute to long-term infrastructure stability and operational excellence
• Support cloud infrastructure deployment, including virtual machines and secure workloads in Azure environments

Requirements

• 10+ years of experience in systems engineering, security engineering, or infrastructure security roles
• Strong hands-on experience with Azure cloud environments and hybrid identity architectures
• Deep knowledge of identity management, PKI systems, and certificate lifecycle processes
• Experience working in compliance-driven environments aligned with frameworks such as NIST SP 800-171 and CUI/ITAR requirements
• Familiarity with CMMC Level 1 and/or Level 2 environments and audit support activities
• Experience managing endpoint security and compliance using Microsoft Intune and related tools
• Strong understanding of system hardening, secure configuration management, and vulnerability remediation practices
• Background in supporting audits, IT governance frameworks, and compliance documentation
• Excellent problem-solving skills with the ability to operate in complex, regulated environments
• Strong communication skills and experience collaborating across technical and non-technical teams

Benefits

• Fully remote work within the United States
• Long-term, stable contract engagement with consistent workload
• Opportunity to work in highly regulated, security-focused enterprise environments
• Exposure to advanced Azure cloud and enterprise identity architectures
• Collaborative, technically driven engineering culture
• Engagement in mission-critical infrastructure and compliance initiatives
• Continuous professional development through complex, enterprise-scale security challenges
• Predictable full-time equivalent schedule for stability and planning
