Microsoft Corporation Sr.Software Engineer in Bellevue, Washington

If you like challenges and want to learn and practice how to develop advanced big data solutions/techniques that scale to hundreds of Terabyte data and then tens of Petabyte data, in both streaming and batch mode, this is your ideal opportunity. We deal with this scale of data every day. The AIDI (Artificial Intelligence and Data Infrastructure) Data Mining team is looking for an extremely talented, highly motivated and productive software engineer, to work on building the data solutions and services to manage Petabytes of comprehensive real data. Data is critical to the success of modern online services, and our techniques and systems are the key part of the data foundation for multiple product teams across organizations. The team's charter is to design and own the end-to-end data solution for ASG, including partering with data consumers to understand data requirements, collaborating with data producers to collect data signals, building a scalable data processing pipeline to serve the very large scale data, and publishing the comprehensive data signals through a well-organized intuitive data API. Our data is huge and used heavily by many feature teams for their development and measurement, including Office 365, Office Clients, Skype, Skype for Business, Cortana, Bing, Ads, and MSN.

The scale of data provides great technical challenges. We need experience with system architecture, design and implementation skills as well as big data infrastructure knowledge to build a scalable system that can effectively and efficiently process the very large-scale data, in both streaming and batch mode. We need a candidate with a powerful sense of data, solid data mining skills and good understanding of online business to design a clean data interface which is able to manage the comprehensive and complicated data schema, and to promote and guide the data consumption in ASG. You will play a critical role in solving these problems with your strong leadership, development, research, and problem-solving skills. You will be part of a very strong and fun team, building very large scale data infrastructure, staying touch on the state-of-the-art big data technologies in both open source and Microsoft own stack, developing advanced and practical data mining, machine learning, statistics, and measurement techniques for solving the hottest and most challenging problems in the world and generating real impact. You are empowered to change multiple product teams to be data driven and influence millions of end users. You will have opportunities to work together with world class developers and researchers to stay in the forefront of advancing technologies, such as big data, data mining, data processing platform, metrics, BI, online experimentation, statistics, cloud computing, search, ads, and social networks.
