Job description

The IT Cybersecurity Engineer II provides mid-level engineering support for the architecture, operation, automation, and continuous improvement of Orion's cybersecurity posture across on-premises, cloud, and hybrid environments. This role is responsible for evaluating and strengthening the overall security architecture, and for enhancing and automating existing security tooling to improve detection, response, and operational efficiency. The role also owns the security and integrity of Orion's SIEM and SOAR environment, ensuring the platforms that detect and respond to threats are themselves properly access-controlled, hardened, and monitored. The position holds global ownership of endpoint security review and administration, ensuring consistent policy enforcement, coverage, and hardening across the environment.

While the primary focus of this role is cybersecurity engineering, the Cybersecurity Engineer II is expected to be well-rounded across core infrastructure disciplines. The role actively cross-trains and provides backup support with the Infrastructure team and participates in shared operational and on-call responsibilities. This role works under the direction of IT leadership while partnering with the Infrastructure team, Service Desk, Applications, and business stakeholders to maintain a secure, resilient, and well-documented technology environment.

This role supports cybersecurity technologies and services including endpoint detection and response (EDR/XDR), network detection and response (NDR), SIEM and SOAR platforms, identity security, email security, vulnerability management, security monitoring and alerting, and security automation, in addition to cross-functional support of virtualization, backup, and related on-premises infrastructure.

The incumbent must support Orion's guiding beliefs and core values centered on Safety, Quality, Delivery, and Teamwork, and most importantly, built upon the all-important foundation of Integrity.

SPECIFIC RESPONSIBILITIES

Cybersecurity architecture and posture

• Evaluate Orion's overall cybersecurity architecture and posture, identifying gaps and recommending improvements aligned with security best practices and industry frameworks (for example, NIST, CIS Controls, Zero Trust principles).
• Partner with IT leadership to design and evolve a layered security architecture across endpoint, network, identity, email, and cloud environments, informed by findings from penetration tests, vulnerability assessments, and audits.
• Translate penetration test and assessment findings into prioritized remediation plans and architectural changes, tracking implementation through to closure.

Security tooling enhancement and automation

• Serve as the primary engineer responsible for enhancing, tuning, and automating Orion's core security platforms, including Darktrace and Microsoft Defender (Defender for Endpoint, Defender for Identity, Defender for Cloud Apps, Defender for Office 365).
• Develop and maintain automation, scripts, and workflows (for example, PowerShell, KQL, Logic Apps/Sentinel automation, or equivalent) to streamline detection, alert triage, response actions, and reporting, reducing manual security operations effort.
• Continuously tune detection rules, alert thresholds, and correlation logic to reduce false positives and improve signal quality across security platforms.
• Evaluate emerging security tools and capabilities and recommend enhancements or additions to the security tooling stack.

SIEM and SOAR platform security

• Own the security, access control, and configuration integrity of Orion's SIEM and SOAR environment, ensuring the platforms responsible for detection, correlation, and automated response are themselves hardened against unauthorized access, tampering, or misconfiguration.
• Administer role-based access, log source onboarding, and data retention within the SIEM to protect the confidentiality and integrity of security event data used for detection, investigation, and audit evidence.
• Build, test, and maintain SOAR playbooks and automated response actions, applying change control and peer review to prevent unintended or unauthorized automated actions in production.
• Monitor SIEM/SOAR platform health, log ingestion completeness, and playbook execution to ensure detection and response coverage is not silently degraded.

Endpoint security ownership

• Own the global review, configuration, and administration of endpoint security, across all Orion locations, devices, and business units.
• Monitor endpoint security coverage, policy compliance, and protection status; identify and remediate gaps in onboarding, policy application, or protection posture.
• Manage endpoint security policies, attack surface reduction rules, device configuration baselines, and vulnerability management workflows tied to endpoint protection.
• Review and respond to endpoint-related security alerts and incidents, coordinating containment, remediation, and root-cause analysis.

Security monitoring, detection, and incident response

• Monitor security alerts, logs, and telemetry from Darktrace, Microsoft Defender, the SIEM, and related platforms; investigate and respond to potential threats and security incidents.
• Support incident response activities, including detection, containment, eradication, and post-incident documentation and lessons learned.
• Perform vulnerability scanning, risk assessment, and remediation coordination across infrastructure and endpoint environments.

Compliance, audit, and governance support

• Support CMMC and NIST SP 800-171 compliance activities, including control implementation, evidence collection, audit support, and remediation of identified findings.
• Maintain security documentation, including architecture diagrams, standard operating procedures, playbooks, and control evidence, to support auditability and operational consistency.
• Assist with security risk assessments, policy development, and control reviews in coordination with IT leadership.

Cross-training and infrastructure support

• Cross-train and maintain working proficiency with core on-premises infrastructure platforms managed by the Infrastructure team, including VMware virtualization and Veeam backup and recovery.
• Provide backup coverage for infrastructure operations as needed, including virtualization, backup/recovery, storage, and related on-premises systems, to reduce single points of knowledge given the size of the IT team.
• Partner with the Infrastructure team on projects and changes that have security implications, ensuring security requirements are incorporated into infrastructure design and operations.

Documentation and continuous improvement

• Maintain accurate technical documentation, including security architecture diagrams, configuration standards, runbooks, and change records.
• Identify and communicate opportunities to improve security posture, tooling effectiveness, and operational efficiency; participate in continuous improvement initiatives.
• Coordinate effectively with the Infrastructure team, Service Desk, Applications, vendors, and other stakeholders to resolve incidents, support projects, and ensure smooth handoffs.

After-hours response and operational readiness

• Respond to off-hour security alerts, calls, emails, or notifications as needed to maintain security monitoring coverage and operational uptime.
• Ensure incident response communications and handoffs are clear, timely, and documented.

Broader IT support and other duties

• Support broader IT and security projects and perform other related administrative and technical duties as assigned by IT leadership.
