Cyber Defense Engineer

Alert Triage & Monitoring

• Monitor and triage security alerts across SIEM, EDR, and CSPM platforms covering both corporate and product environments.
• Investigate alerts to determine scope, severity, and whether escalation is warranted.
• Leverage AI-assisted triage and enrichment tools to accelerate analysis and reduce mean time to detect.
• Classify, document, and track alerts through the full lifecycle using ticketing and case management systems.
• Incident Response & Investigation
• Participate in or lead incident response engagements from detection through remediation, including evidence collection, forensic analysis, root cause determination, and stakeholder communication.
• Conduct investigations across SIEM, EDR, CSPM, and cloud-native log sources including identity provider logs, cloud audit trails, and network flow data—spanning both corporate and product infrastructure.
• Execute established IR runbooks across identity, endpoint, cloud, and email investigation workflows.
• Manage or assist with evidence handling, forensic artifact collection, and chain-of-custody procedures.
• Produce clear, decision-ready incident summaries and post-incident reports for both technical and leadership audiences.
• Detection Engineering & Threat Intelligence
• Contribute to the design, implementation, and tuning of detection rules across SIEM and EDR platforms, with a focus on reducing false positives and closing coverage gaps.
• Translate threat intelligence (CVE advisories, CISA alerts, vendor bulletins, open-source feeds) into actionable detection content, with particular attention to threats targeting privileged access tooling and supply chain attack vectors.
• Help maintain and evolve detection coverage mapped to MITRE ATT&CK.
• Partner with threat hunting peers to validate detection logic through hypothesis-driven hunts.
• AI Integration & Automation
• Use AI-driven tools for alert triage, enrichment, and investigation as a standard part of daily operations.
• Contribute to the evaluation, integration, and optimization of AI and automation capabilities across the team’s workflows.
• Assist in designing prompts, agent workflows, or LLM-based pipelines that augment analyst capabilities and reduce manual effort.
• Partner with engineering teams to improve log ingestion, data quality, and tool integrations.
• Operational Excellence
• Maintain daily operational notes and shift handoff documentation.
• Contribute to and refine IR runbooks, playbooks, and standard operating procedures.
• Participate in on-call rotation for after-hours incident escalation.
• Track and report on operational metrics (MTTD, MTTR, MTTC, false positive rate) and identify improvement opportunities.
• Participate in tabletop exercises, purple team activities, and post-incident reviews.
• What You’ll Bring
• 4+ years of experience in a SOC, security operations, or incident response role.
• Understanding of common attack frameworks (MITRE ATT&CK), network protocols, and endpoint behavior.
• Experience with at least one SIEM platform and familiarity with writing search or detection queries.
• Familiarity with EDR platforms and cloud environments (IaaS preferred).
• Comfort using AI systems (e.g., LLM-based assistants, copilots, or AI-driven analysis tools) as part of security workflows.
• Strong written communication skills; able to document findings clearly and concisely for both technical and non-technical audiences.

• Experience leading or co-leading complex incident response engagements from triage through remediation.
• Experience with identity and access management platforms and cloud security posture management tools.
• Scripting and automation skills (Python, PowerShell, or equivalent) applied to security workflows.
• Familiarity with SOAR platforms or orchestration tools for automated response and enrichment.
• Experience designing or implementing AI agent architectures, LLM-based automation pipelines, or prompt engineering for security use cases.
• Experience building or contributing to threat intelligence programs or detection-as-code pipelines.
• Understanding of the privileged access management landscape and the threat actors that target it.
• Track record of evaluating and adopting emerging technologies in a production security environment.
