Subject: Redmond, WA: Business Process Analyst/Decision Scientist, #232154 at Microsoft

The Analyst will work closely with IT and other data/systems providers (internal and external) to enhance systems, trouble-shoot data issues and be the expert at building predictive, statistically valid models.

This Group manages the operations of the ecommerce platform for Microsoft online businesses such as MSN, Xbox Live, bCentral, Office, and many others. The Fraud and Risk team in particular, is responsible for assuring that we build a solid foundation for our platform to support our global ecommerce operations.

Candidate must be a customer-focused, detail-oriented, results-driven business professional with great communication skills having a strong knowledge of databases and statistical techniques. It is recommended that the candidate also have a background in the payments and fraud prevention space. We are passionate about building world-class solutions promoting trustworthy ecommerce and we are looking to complement our high caliber team with this specialized skill. The Fraud and Risk Decision Scientist analyzes, optimizes, and implements computational rules used to monitor and control activity on Microsoft's ecommerce platform in accordance with internal risk and governance policies. Because of the number, complexity, and interdependency of rules, the optimization of rule sets is a non-trivial statistical, machine learning and text analytics problem that spans numerous databases. It takes a special candidate to find the ideal solution. If you believe you are that individual, please contact us.

Responsibilities:

Use statistical techniques to design predictive models that detect fraud
Iteratively test, refine and improve existing models
Implement computational rules to monitor and enforce fraud prevention policies
Manage the day-to-day aspects of systems (SAS, data sources, workflow systems, etc.) to ensure that the modeling and production infrastructure is optimized
Improve rule performance by analyzing misses, false positives, hit rates, and customer feedback.
Organize and document to simplify rule sets
Contribute to global rule set by building best-practice rules and understanding international needs and payment types
Collaborate with relevant team members to insure rules are in alignment with business needs
Assist the Software Development and Program Management teams in testing and deploying rule set

Requirements:
1. Master's degree in Statistics, Operations Research, or Machine Learning (PhD a plus) and a minimum of 3-5 years' related work experience. Display a proven ability to use modeling, optimization, and machine learning or text classification algorithms.
2. Successful execution of this role will require that the Analyst 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 we are able to reduce fraud and other violations of MSN's user agreement as a result of better and more proactive data and monitoring.
3. Additionally, the candidate must demonstrate high energy/creativity, a passion for analyzing highly complex data sets, strong communication and project management skills, strong debugging skills, an entrepreneurial spirit, a relentless customer-focus, a practical understanding of quantitative methods, and superb attention to detail.
