About the team

The Security Incident Response team works to analyze, investigate, and respond to threats before they impact ’s business or users. From external attacks to insider threats, our goal is to respond with speed and precision, remediate, and support the incident postmortem process. The team is distributed, working across multiple AMER time zones, and will regularly coordinate with stakeholders in EMEA and APAC.

What you’ll do

You will leverage your security engineering experience to improve incident response capabilities at . With an emphasis on user and entity behavior analytics, as well as endpoint hardening, you will gain a deep understanding of ’s systems, tooling, and workflows to be able to differentiate between legitimate and malicious activity. Using both threat intelligence and collected telemetry, you will guide and build -specific signals enrichment logic and incident response solutions that scale with our company. Lastly, your analytic capabilities will be critical during security incidents to reduce uncertainty, uncover root causes, and inform future prevention and detection mechanisms.

Responsibilities

• Analyze and investigate a broad range of threats or activities occurring on client devices
• Develop requirements for detection models and enhancements to existing systems
• Collect, transform, and ingest raw data from disparate sources into threat detection pipelines
• Streamline incident response capabilities, ensuring the tooling and processes are clear
• Work cross-functionally with security engineering and data science teams to build solutions for analyzing security events data at scale and protecting networks, systems, and data from threats
• Provide actionable insights to help identify, prevent, detect, and respond to anomalous or potentially malicious user and entity activity
• Act as the subject-matter expert and primary contact for stakeholder teams invested in Security Analytics and Detection programs as well as -wide security initiatives
• Collaborate effectively with teammates, leading projects, mentoring others, and developing and championing quality standards within the team
