What if your job description were simply “make tomorrow better?” Every day at Microsoft, we bring an insatiable curiosity to the workplace, challenging ourselves to reimagine what it is and what it can be. We build on what’s come before to create what’s next. We help shape the future and we empower billions of people around the globe.

We are the computational advertising team in the AI & Research organization at Microsoft. We are looking for candidates with research and applied experience in machine learning related areas. Search advertising is a $100 billion market worldwide. Microsoft's Bing search engine supports over 30% of desktop search in the US, with similarly significant presence in many other countries.

We are a team of applied scientists working on machine learning components in the whole sponsored search stack. Our team works on problems related to machine learning, deep learning, natural language processing, image understanding, optimization, information retrieval, auction theory, among others. Our work entails building large-scale machine learning systems for ad matching, filtration, ranking, and multiobjective optimization, and a number of other ML-driven business problems. You will design, implement, analyze, tune complex algorithms and ML systems and the supporting infrastructure for operating on large datasets. You will collaborate with top machine learning scientists and engineers in delivering direct business impact. We're looking for sound understanding and insight into productionizing machine learning models in large-scale systems, an ability to pick up new technical areas, as well as a commitment to developing, delivering, and supporting algorithms in production.

Responsibilities

• Develop novel algorithms in the space of sponsored search to constantly improve the operational efficacy and monetization impact to stake holders  
• Analyze Giga/Tera bytes of logs and create observation/opportunities and avenues of improvements in the system 
• Identify and apply machine learning solutions at various aspects of the system stack 
•  Monitor for alerts and root cause the live/off-line aspects for any abnormalities in the system  
• Ideate on newer aspects of advertising avenues and augment the platform with richer products for the stake holders 

Qualifications

• MS/BS in CS/EE, mathematical or machine learning related disciplines, with 3 or more years of experience
