Job description

ThreatMetrix®, A LexisNexis® Risk Solutions Company, provides an end-to-end platform for digital identity intelligence and trust decisioning. We instantly detect high-risk transactions and dynamically score them, enabling digital businesses to safely grow online revenue and personalize the digital experience for trusted customers. With ThreatMetrix, sales conversion rates rise and fewer customers get flagged for review. Fraud, security and payment operations run more efficiently. Operational costs decrease and, best of all, fraudsters often leave for greener pastures. We believe security doesn’t need to come at the expense of profitability. Security and fraud prevention simply needs to be better, not harder for legitimate customers. That’s profitability and security without compromise.

As a Data Scientist, you’ll use global data from the largest real-time fraud detection platform to craft solutions for our enterprise customers. Your experience with data analysis, statistical modeling, and machine learning will lead to immediate real-world impact in the form of lower customer friction, reduced fraud losses and as a result, increased customer profitability. You’ll leverage a real- time platform analyzing billions of transactions per month for some of the largest companies operating in Financial Services, Insurance, e-Commerce, and On-Demand Services. These tools will allow you to attain a unique perspective of the Internet and every persona connected to it. On top of driving your own innovation projects, you’ll be continually collaborating with internal product and engineering teams, customer-facing account teams, and external business leaders and risk managers. The comprehensive models you build will go head-to-head against some of the most motivated attackers in the world to protect billions in revenue.

  • Statistics: Use statistics and creativity to extract possible risk indicators and trends from complex, sometimes unstructured data sources (including sensor data) and transform them into potential model features
  • Customer focus: Demonstrate a professional and customer-centric persona when interacting directly with customers via phone, e-mail, and chat
  • Innovation: Percentage of time dedicated to self-driven research. (Recent examples include design of a globally adopted genetic algorithm, feature engineering over cellphone sensor data, network analysis over UK banking industry)
  • Collaborate: Collaboration with ThreatMetrix teams including Products, Engineering and your colleagues to continually redefine best practices and help shape and improve our new and existing products

  • Use your strong attention to detail and ability to craft a story through data, delivering industry-leading presentations for

external and executive audiences
