About the Job

Requirements

  • A bachelor's degree in computer science, information technology, engineering, information systems, cybersecurity, or a related area and two years of experience in intrusion analysis or a related area at a technology, retail, or data-driven company; alternatively, four years of experience in intrusion analysis or a related area at such a company.
  • Hands-on experience with endpoint detection and response and security information and event management technologies across on-premises and cloud environments.
  • Experience with security orchestration, automation and response, email security, incident and case management, firewalls, intrusion prevention systems, security correlation, and detection use-case development and deployment.
  • Hands-on cybersecurity investigation skills, including malware analysis, phishing and email analysis, network and endpoint investigation, and Windows and Linux operating-system analysis.
  • Practical exposure to artificial intelligence and generative AI tools such as Copilot, ChatGPT, and Gemini, with the ability to use them responsibly and critically in cybersecurity workflows.
  • Ability to develop or adapt security queries, scripts, and automation to support investigation and operational efficiency.
  • Experience working with global teams and flexibility to work rotational shifts as business needs require.
  • Professional judgment to research and integrate relevant evidence, apply fact-based criteria, identify root causes, and make defensible recommendations.
  • Ability to prioritize, use established tools and processes, manage time and operational challenges, and deliver against business and security objectives.
  • Ability to develop practical improvement plans, anticipate potential problems, and identify opportunities to streamline processes and improve SOC performance.
  • Ability to communicate technical findings and risk clearly, share timely updates, listen actively, and prepare effective documentation and presentations.
  • Ability to build collaborative relationships across teams, organizational levels, and diverse backgrounds.
  • Ability to understand stakeholder needs and use data, analysis, and insights to improve service and security outcomes.
  • Ability to follow policies and procedures, protect sensitive information, and support compliance expectations.
  • Ability to adapt to changing priorities, embrace new responsibilities and technologies, and continuously update and share knowledge.
  • Strong investigation, reasoning, decision-making, and problem-solving skills in complex and fast-moving situations.

Responsibilities

  • Monitor, triage, analyze, investigate, and support remediation of cyber events using defined SOC procedures, playbooks, escalation paths, and service expectations.
  • Investigate endpoint, network, email, identity, cloud, Windows, and Linux telemetry; correlate evidence across data sources to determine scope, impact, root cause, and recommended actions.
  • Run approved commands, queries, scripts, and automation for assigned areas of work while maintaining operational controls and documentation.
  • Identify indicators of compromise, suspicious behaviors, attack patterns, and emerging risks; escalate confirmed or high-risk incidents to appropriate response teams.
  • Communicate with technical and business stakeholders during troubleshooting and security events, providing timely status, findings, risk context, and recommended next steps.
  • Provide actionable input to improve alert logic, correlation rules, detection use cases, thresholds, enrichment, prioritization, and suppression of known false positives.
  • Identify opportunities for new risk detection based on investigation trends, threat intelligence, recurring incidents, control gaps, and observed attacker behavior.
  • Partner with engineering and platform teams to validate and operationalize detection improvements across SIEM, EDR, SOAR, email security, firewall, IPS, and cloud security tools.
  • Capture investigation learnings, recurring patterns, root causes, and operational gaps; recommend measurable improvements to SOC processes, playbooks, documentation, and analyst workflows.
  • Use approved AI and generative AI capabilities to assist with investigation summarization, evidence correlation, query and script drafting, threat-context synthesis, case documentation, and recommendation generation.
  • Validate AI-generated analysis against authoritative telemetry and security evidence before using it for incident decisions, escalation, remediation, or stakeholder communication; maintain accountability for final conclusions.
  • Assess AI-assisted investigation quality by identifying inaccurate conclusions, missed evidence, weak reasoning, hallucinations, incomplete recommendations, and inconsistent outputs, and provide structured feedback for improvement.
  • Help develop and refine prompts, analyst workflows, evaluation criteria, test cases, and feedback loops to improve the accuracy, consistency, explainability, and operational usefulness of AI-assisted SOC analysis.
  • Identify appropriate opportunities to integrate AI and generative AI with SIEM, SOAR, EDR, threat intelligence, case-management, and knowledge-management workflows to reduce repetitive work and accelerate triage and investigation.
  • Apply responsible-AI and security principles when using AI tools, including data handling, confidentiality, access controls, human oversight, traceability, and compliance with company policies and approved-use requirements.
  • Monitor AI-assisted workflows for quality and operational risk, and escalate cases where AI output could create false assurance, inappropriate remediation, data exposure, or other security impact.
  • Contribute to AI readiness across the SOC by documenting effective practices, sharing lessons learned, and supporting analyst adoption and training for approved AI-enabled capabilities.
  • Support cybersecurity intelligence and security-operations solutions by gathering requirements, researching technologies, participating in solution reviews, and contributing to supplier and product evaluations.
  • Develop and review system, process, investigation, and operational documentation to support consistent execution and knowledge transfer.
  • Maintain current knowledge of cybersecurity threats, attacker techniques, security technologies, automation, and AI and generative AI developments relevant to SOC operations.
  • Participate in team assignments and projects, provide progress updates, contribute to team meetings and technical discussions, and support cross-functional initiatives.
  • Create and review case notes, standard operating procedures, playbooks, knowledge articles, metrics, reports, and presentations for management, technical teams, customers, suppliers, and other stakeholders.
