In this team you'll have a unique opportunity to have first-hand exposure to the strategy of the company in key security initiatives, especially in building scalable and robust, intelligent and privacy-safe, secure and product-friendly systems and solutions.

Responsibilities:

  • Enable and contribute to establishing fast and continuous threat response, in partnership with risk data mining engineers and product partners, by building advanced analytical tools and derive data insights.
  • Analyze security and product data to uncover latest attacker techniques and abuse vectors. Generalize them into data mining opportunities in product features; modeling signals, labels and algorithms; measurement and process effectiveness.
  • Enable and contribute to establishing robust, powerful and privacyaware automated defense, in partnership with risk data mining engineers, by leveraging risk systems, machine learning tools and business resources to build and improve risk control rules, models and products.
  • Abstract and build risk measurements that best connect risk research, risk operation, risk defense and business/community health with data stories, drive strategic and tactical risk control roadmaps with such metrics collaboratively with product/business/engineering stakeholders.
  • Uphold adversarial threat response in a specific business area (e.g. TikTok, growth, live streaming, ads, ecommerce, Lark) to be consistently prompt, rigorous and clean. Define and uphold data science practice excellence and metricdriven decision making process. Bridge technical and communication gaps between engineering, product and business teams.

Qualifications:

  • Bachelor, master or PhD degree in an advanced field of technology or management or other equivalent majors. E.g. Computer science, statistics, internet security, finance.
  • Proficiency in data analysis and statistical analysis tools such as SQL, R and Python.
  • 4+ years of strong industry experience in predictive analytics and/or statistical modelling. Successful tracking records in solving large scale data mining problems such as relevance, recommendation, antifraud and relevant financial problems.
  • Strong ownership, communication and collaboration skills to endtoend own one or more critical platform/community security business fronts that are highly adversarial, ever expanding, and by nature widely cross functional.
Preferred

  • Consistency at exercising data science best practice in modern internet industry or academic world. Persistence in reasoning with data, interpreting data objectively, and making datadriven decisions.
  • Minimum 5 years relevant work experience from a largescale internet business
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.
