Subject: San Jose, CA: Statistician, Risk Analytics at eBay, Inc
The Statistician, Risk Analytics will report to the Manager of Risk
Analytics, and be dedicated to the conception, design, implementation
of data models and reports that predict and prevent prohibited
activity on eBay's website, including fraud and other violations of
eBay's user agreement. These predictive models and reports will
become a primary tool used by eBay's Trust & Safety Department
Representatives in preventing violations, and in disciplining
violators (including legal prosecution in some cases). Successful
execution of this role will require that the Statistician be an expert
in database record manipulation (mainly SAS/SQL) and statistical
modeling techniques (logit, decision-tree, neural networks, cluster
analysis, etc. using SAS). The key measure of success will be the
degree to which Trust & Safety Representatives are able to reduce
fraud and other violations of eBay's user agreement as a result of
better and more proactive data and monitoring.
Summary of responsibilities:
- Use statistical techniques to design and code predictive models that
detect fraud, etc. Iteratively test, refine, and improve the
models. In this role, the Statistician will be required to be
expert in building predictive, statistically valid models.
- Generate reporting on performance of models.
- Manage the day-to-day aspects of systems (SAS, data sources,
workflow systems, etc.) to ensure that the modeling and production
infrastructure is optimized. In this role, the Statistician will
work closely with IT and other data/systems providers (internal and
external) to enhance systems, trouble-shoot data issues, etc.
Education and/or Relevant Experience
Master's degree in Statistics (PhD a plus) and a minimum of 3-5 years'
work experience in a relevant field, preferably within the
Data-Mining, Quantitative Research, or Risk Management Department of a
financial institution. Proven ability to build statistical models
using SAS, and manage junior SAS modelers/statisticians.
Additionally, the candidate must demonstrate high energy/creativity, a
passion for analyzing highly complex data sets, a relentless
customer-focus, an entrepreneurial spirit, strong interpersonal and
communication skills, a deep practical understanding of quantitative
methods, and superb attention to detail.
This position is located in San Jose, CA. We do not provide for
relocation. This is a full-time position, no contractors need apply.
