What You’ll Do

• Cybersecurity Detection Engineering: Build, test, and maintain detections that protect Cox Automotive’s internal systems as well as its domestic and international businesses.
• Contribute to the Detection Engineering roadmap and objectives by delivering assigned work and recommending improvements to senior engineers.
• Use AI tools and large language models daily to accelerate detection development, query writing, log analysis, investigation, and documentation, and validate AI output for accuracy before use.
• Build and maintain AI-assisted detection and triage workflows (such as prompts, agent steps, and automated enrichment) as part of detection solutions, following established patterns and guidance from senior engineers.
• Develop and tune detection rules, automated remediation playbooks, and alerts using SIEM, EDR, and SOAR platforms, tailored to Cox Automotive’s enterprise and customer threat landscape.
• Use the MITRE ATT&CK and ATLAS frameworks to map detections, assess coverage, and help identify gaps.
• Monitor detection performance and tune detections to reduce false positives and improve effectiveness.
• Collaborate with the Threat Detection and Response team to continuously improve the identification and response to threats.
• Perform attack simulation testing to validate the efficacy of detection use cases, using established tools and procedures.
• Support purple teaming exercises in collaboration with the Vulnerability Management team.
• Support SIEM/Data Lake log ingestion by onboarding log sources, validating parsing and data quality, and troubleshooting ingestion issues, in collaboration with Cyber Defense Engineering counterparts.
• Evaluate, validate, tune, and recommend retirement of detections as needed.
• Collect and report detection metrics, such as alert volume, false positive rates, and coverage, on a routine basis.
• Build and maintain operational guidelines, diagrams, and documentation for security detection and response.
• Participate in an off-hours support rotation for security detection and response activities.
• Incident Response: Collaborate with the Incident Response team to support rapid detection and containment of cyber threats.
• Build threat detection logic during incident response, with guidance, to accelerate threat identification and containment.
• Contribute to improving detection and response processes based on lessons learned from incidents.
• Threat Intelligence Integration: Apply threat intelligence from the Threat Intelligence team to build and enhance detections.
• Research new and emerging threats and share findings with the team to inform detection priorities.
• Stakeholder Collaboration: Partner with other Cybersecurity, Engineering, and Product teams to support successful deployment of detection and response solutions.
• Support Product teams in implementing customer-focused detection and response solutions, with guidance from senior engineers.
• Communicate detection capabilities and findings clearly to technical and non-technical stakeholders and escalate issues to senior engineers or leadership as needed.
• Governance and Compliance: Follow detection and response processes that adhere to regulatory requirements and industry standards (e.g., GDPR, PCI-DSS, NIST).
• Maintain documentation of detection use cases, processes, and configurations.
