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 the company. With an emphasis on user and entity behavior analytics, as well as endpoint hardening, you will gain a deep understanding of the company'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 the company-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 the company 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 the company-wide security initiatives
• Collaborate effectively with teammates, leading projects, mentoring others, and developing and championing quality standards within the team

Who you are

We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement.

Minimum requirements

• 3+ years experience analyzing large data sets to solve problems and/or building models with a behavioral approach to security
• B.S. or M.S. Computer Science or related field, or equivalent experience
• Expert knowledge of Python and SQL, and familiarity with other programming languages
• Existing experience with log analysis (e.g. first or third party applications, system / data access, event logs), network security, digital forensics, and incident response investigations
• Proficiency with developing and using novel analytical methods to build, automate, and improve detection and response systems
• Ability to communicate results clearly and focus on impact
• Ability to think creatively and holistically about reducing risk in a complex environment

Preferred qualifications

• An adversarial mindset, understanding the goals, behaviors, and TTPs of threat actors.
• Experience with software engineering, data processing and analysis tools (e.g. Databricks/Jupyter, Trino, etc.)
• Familiarity with common open-source frameworks for big data processing and/or data science (PySpark, Pandas, Sci-kit Learn, etc.)
• Experience with tactical threat intelligence and/or hunting for sophisticated threat actors in an enterprise environment
• Familiarity with network observability, security software, or data engineering solutions (osquery, Splunk/LogScale, etc.)
• Experience in one or more of the following areas: user and entity behavior analytics (UEBA), security information event management (SIEM), security orchestration automation and response (SOAR), or data loss prevention (DLP)
