The Data Science team at Groupon owns the heart of our decision making system that provides value to the millions of merchants and customers that use our platforms on a daily basis. We use industry standard data technologies, data science methods, and machine learned models to build solutions that tune an inventory of merchant-provided goods and services to our customers' needs. For each merchant we provide direction on how to compete successfully in their unique local marketplace. For each customer, Groupon leverages real-time matching algorithms to personalize deals for businesses in their local area. We use the tremendous level of daily traffic on our site and mobile apps to identify patterns and understand the evolving needs of our customers and merchants. Groupon constantly monitors the performance of our models and algorithms to improve predictive accuracy while staying accountable to the fundamentals of our business.

Data Science is a quickly evolving discipline and Groupon is committed to ensuring that our teams uses modern, career building tools that keep pace with the rest of the industry.

Your role as an Machine Learning Engineer will be to understand the behavior of our customers and merchants and translate that understanding into actionable insights that impact our real-time revenue and user experience. Groupon’s Machine Learning Engineers are also expected to have expertise and continued interest in building and maintaining low latency distributed systems providing real-time inference.  Team members are highly collaborative, have an authentic passion for trying new algorithms, a willingness to experiment, and a drive to execute.

We're a "best of both worlds" kind of company. We're big enough to have resources and scale, but small enough that a single person has a surprising amount of autonomy and can make a meaningful impact. We're curious, fun, a little intense, and kind of obsessed with helping local businesses thrive. Does that sound like a great way to grow your career? Let's get into the details: 

As a Machine Learning Engineer, you will:

  • Develop and maintain algorithms, data pipelines, automated processes, and services to create a data science backed solution that meets a business need for improving our customer or merchant platforms
  • Build machine-learned models in areas such as user segmentation, traffic change detection, personalized recommendations, conversion rate prediction of visiting customers, or time-series demand forecasting
  • Work with product and business teams to identify questions and issues for data analysis and experimentation
  • Design and develop processes and systems which consolidate, analyze and generate actionable insights from diverse data sources
  • Effectively communicate meaningful insights to partners across Groupon
