The Lead Cybersecurity Network Threat Analyst investigates and researches cyber threats using network analysis tools and techniques. The Network Threat Analyst derives actionable threat intelligence and provides analytical support to the Chief Security Office Cyber Operations organization.

The Network Threat Analyst will:

• Perform deep technical analysis of suspicious network activity using internal network collection platforms, including but not limited to flow analysis, packet analysis, review of metadata and intelligence sources.
• Use proprietary and open-source intelligence sources to analyze and interpret network telemetry, produce informative products, briefs, reports, and indicators of compromise.
• Configure and optimize internal and external threat monitoring systems to increase AT&T's intelligence holdings to maintain a high standard of quality for network cyber indicators.
• Document findings and recommend remediation action to a team of highly technical professionals with expertise in cybersecurity, threat intelligence, threat detection, networking, log, malware, and vulnerability analysis.
• Identify and implement new analysis techniques, beyond those currently available.
• Detect network threats beyond the capabilities of common tools.
• Reduce the risk of False Positive or False Negative detections and improve detection logic for advanced and targeted threats that are missed by existing tools and controls.
• Implement new automation solutions to improve workflow efficiency.
• Create detailed and accurate reports and professional briefings documenting findings to share with a variety of audiences.
• Recommend and oversee implementation of technical requirements to ensure platform meets analysis needs.
• Develop, test, and operationalize AI-assisted threat analysis workflows (e.g., enrichment, clustering, summarization, and triage) to improve speed and consistency of investigations.
• Evaluate and validate AI outputs for accuracy, bias, and security relevance; apply human-in-the-loop review and document decision rationale for key analytical judgments.
• Use AI tools in alignment with enterprise security, privacy, and data-handling requirements; ensure sensitive data is protected and only approved tools and datasets are used.
• Create and maintain reusable prompts, playbooks, and automation scripts that integrate AI with existing detection, telemetry, and case-management workflows.
• Define and track quality metrics for AI-assisted analysis (e.g., precision/recall impact, time-to-triage, false positive reduction) and iterate based on outcomes.
• Partner with detection engineering, data science, and platform teams to onboard new AI capabilities, test changes safely, and transition prototypes into repeatable operations.
• Provide guidance to analysts on effective and responsible use of AI during investigations, including limitations, verification steps, and escalation paths.

• Bachelor's degree in computer science, cybersecurity, information technology, or a related field.
• 5+ years of experience in cybersecurity, threat intelligence, networking or a related field.
