The ECRC team works to prevent and detect any risk attempts in TikTok e-commerce platforms and to mitigate the negative impact on our customers and Selling Partners.

  • Collaborate with cross-functional teams from multidisciplinary science, engineering, and business backgrounds to enhance current automation processes.
  • Develop efficient data querying infrastructure for both offline and online analysis, uncover evolving attack motion, identify weaknesses and opportunities in risk defense solutions, explore new space from the discoveries.
  • Define risk control measurements. Quantify, generalize, and monitor risk-related business and operational metrics. Align risk teams and their stakeholders on risk control numeric goals, promote impact-oriented, data-driven data science practices for risks.
  • Maintain technical documents and communicate results to diverse audiences with effective writing, visualizations, and presentations.

Qualifications:

  • Bachelor's or Master's degrees in Computer Science, Mathematics, Machine Learning, or other relevant STEM majors (e.g., finance if applying for financial fraud roles). Experience programming in Java, C++, Python, or related languages.
  • 4+ years of hands-on experience in building and delivering machine learning models for large-scale projects.
  • Track record of developing and implementing models and visualizations using programming and scripting (Scala, Python, R, Ruby, and/or Matlab).
  • Experience using various forecasting, machine learning, and statistical tools and communicating results, plans, and/or risks clearly.
  • Ability to think creatively and solve problems.

TikTok is committed to creating an inclusive space where employees are valued for their skills, experiences, and unique perspectives. Our platform connects people from across the globe, and so does our workplace. At TikTok, our mission is to inspire creativity and bring joy. To achieve that goal, we are committed to celebrating our diverse voices and to creating an environment that reflects the many communities we reach. We believe individuals shouldn't be disadvantaged because of their background or identity, but instead should be considered based on their strengths and experience. We are passionate about this and hope you are too.
