About the role

We're looking for a data-driven professional to help us measure, understand, and improve the performance of our risk strategies - and to stay ahead of evolving fraud threats by designing and deploying data-driven solutions with real-world impact. You'll work directly with clients to understand their unique fraud challenges, rapidly prototype proof-of-concept models, and build scalable, production-ready solutions using machine learning and graph analytics.

You'll also analyze complex datasets, design metrics, build dashboards, and collaborate closely with stakeholders across the business to drive decision-making and optimize outcomes.
This is a hands-on, high-impact role ideal for someone who thrives at the intersection of data science, client-facing problem solving, and real-time risk.

  • Conduct in-depth analyses to uncover insights contributing to fraud reduction and higher approval rates for our clients

  • Work directly with clients to understand their fraud challenges and translate complex data insights into clear, actionable recommendations

  • Use data and models to support the development of risk mitigation strategies and interventions while preserving and improving the user experience

  • Create and automate self-serve dashboards leveraging BI tools

  • Collaborate with engineering to scale models into production, optimize performance, and support data instrumentation

  • Partner with cross-functional teams (Business, Product, and Engineering) to translate business requirements into data-driven solutions

What you'll need

  • 7+ years of experience in data science, quantitative modeling, or a data-focused role (product analytics, business analytics) with demonstrated high impact in fraud or risk contexts

  • Strong hands-on experience with Python/R and SQL is essential, with Spark being a nice to have

  • Expertise in BI tools such as Tableau, Sigma, or Metabase

  • Proven ability to structure and analyze complex data using techniques like EDA and cohort analysis, and communicate findings effectively to both technical and non-technical audiences, including clients

  • Sharp critical thinking and creative problem-solving skills with a bias toward action

  • Proficiency in defining, tracking, and communicating performance metrics

Benefits we offer:

  • Generous compensation in cash and equity

  • Early exercise for all options, including pre-vested

  • Work from anywhere: Remote-first Culture

  • Flexible paid time off and Year-end break

  • Health insurance, dental, and vision coverage for employees and dependents - US and Canada specific
