Coordinate upgrades, migrations, integrations, and technology lifecycle management activities.
Incident Response & Threat Management
Act as a senior escalation point during security incidents, infrastructure outages, and other high-impact operational events. Support incident investigations by providing engineering expertise, forensic analysis, and technical troubleshooting. Perform root cause analysis and develop corrective actions to prevent recurring incidents. Monitor emerging threats, vulnerabilities, attack techniques, and industry trends to strengthen defensive capabilities. Recommend and implement security improvements based on lessons learned from incidents and threat intelligence.
Cloud Security & Identity Protection
Secure cloud environments across Microsoft Azure, Microsoft 365, AWS, and other enterprise platforms. Implement and maintain identity security controls, authentication systems, privileged access controls, and modern access management solutions. Support Zero Trust initiatives through improved authentication, authorization, network segmentation, and security monitoring capabilities. Design and enforce secure configurations for cloud and hybrid infrastructure environments.
Security Automation & Continuous Improvement
Develop and support security automations that improve operational efficiency, threat detection, incident response, and compliance reporting. Identify opportunities to improve workflows, eliminate manual processes, and enhance security program maturity. Create and maintain technical documentation, standards, procedures, and platform roadmaps. Evaluate emerging technologies and recommend security investments that improve organizational security posture.
Compliance, Risk & Governance
Support security compliance initiatives and audit readiness efforts across applicable regulatory and industry frameworks. Assist with remediation of security findings, control deficiencies, and identified risks. Conduct security assessments and participate in risk evaluations for new technologies, projects, and vendor relationships. Develop reporting and metrics to communicate security performance and risk to management and leadership teams.
Required Qualifications:
6+ years of experience in cybersecurity engineering, security operations, infrastructure engineering, or a related discipline. Strong experience implementing and supporting enterprise security technologies across multiple security domains. Deep understanding of network security, endpoint security, identity security, cloud security, encryption technologies, authentication mechanisms, and modern security architecture principles. Experience with enterprise security platforms including SIEM, SOAR, EDR/XDR, vulnerability management, DLP, firewalls, and application security tools. Strong understanding of cybersecurity frameworks including NIST CSF, NIST 800-53, ISO 27001, CIS Controls, and MITRE ATT&CK. Ability to troubleshoot complex technical issues and lead remediation efforts across multiple technology domains. Excellent communication skills with the ability to explain technical concepts, risks, and recommendations to both technical and non-technical stakeholders.
Preferred Qualifications:
Experience securing Microsoft Azure, Microsoft 365, AWS, or other cloud environments. Experience supporting compliance programs such as PCI DSS, SOX, HIPAA, or CMMC. Experience conducting risk assessments and security architecture reviews. Industry certifications such as CISSP, CISM, GCIH, GCIA, Security+, CEH, or equivalent. Experience developing security automation, scripting, and orchestration workflows.
Ideal Candidate: The ideal candidate is a senior security professional who combines strong engineering expertise with a strategic mindset. They have a proven track record of designing and supporting enterprise security technologies, improving security programs, and partnering across departments to solve complex business and technical challenges. They are equally comfortable architecting a new security solution, troubleshooting a critical production issue, participating in an incident response effort, or advising leadership on security risk. They take ownership of outcomes, continuously seek opportunities to improve security capabilities, and serve as a trusted technical resource for both the security team and the broader organization.
What Success Looks Like: Success in this role means becoming a trusted owner of critical security platforms, reducing organizational risk through effective engineering and architecture decisions, improving the performance and maturity of security technologies, and enabling the business to operate securely at scale. The successful Security Engineer L3 is recognized as a subject matter expert, a reliable escalation resource, and a key contributor to the company's overall cybersecurity strategy and long-term security roadmap.
