Investigator

About This Role

Investigating high-risk accounts and identifying complex patterns of fraud during incidents is the critical role of the Investigator, who will also lead incident response for product abuse and fraud events. The role involves conducting deep-dive analyses to identify root causes and collaborating cross-functionally to drive improvements in fraud detection and prevention strategies. This position suits an expert in automating response processes through agentic approaches to safeguard merchants and neutralize threats with speed and precision.

Responsibilities

• Investigate, mitigate, and remediate urgent fraud incidents (e.g., ATO, card testing), utilizing FT3-mapped detection and signals enrichment to reduce uncertainty and accelerate response
• As part of incidents, analyze high-risk accounts to identify fraudulent merchants, card testing, account takeovers, and other fraud vectors, classifying them using FT3 (Fraud Taxonomy 3.0) to standardize threat intelligence
• Lead incident root cause analyses to identify gaps in current systems and strategies, leveraging the FT3 framework, data-driven model to drive enhancements and process improvements for emerging fraud risks
• Streamline incident response capabilities, ensuring the tooling and processes are clear, accurate and efficient
• Work cross-functionally with security, fraud and data science teams to build agentic solutions for responding to abuse incidents at scale
• Effectively communicate cross-functionally with legal and policy teams to assess and mitigate risks, while demonstrating strong problem-solving under pressure
• Collaborate effectively with teammates, leading projects, mentoring others, and developing and championing quality standards within the team

Requirements

• 3+ years of experience conducting incident response in security, product abuse or trust domains
• 3+ years experience analyzing large data sets to solve problems and/or building models with a behavioral approach to fraud detection
• 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
• Ability to communicate results clearly and focus on impact
• Ability to think creatively and holistically about reducing risk in a complex environment

Nice to have:

• An adversarial mindset, understanding the goals, behaviors, and TTPs of threat actors
• Experience with engineering, data processing and analysis tools (e.g. Databricks, Trino, etc.)
• Familiarity with common open-source frameworks for big data processing and/or data science (PySpark, Pandas, Sci-kit Learn, etc.)
