Are you a passionate, energetic and technology enthusiast eager to work at a rapid pace with the flexibility to work across our suite of technologies? Are you a problem solver; someone who enjoys debugging code, resolving issues, and creating solutions for common problems? Do you get a little obsessed with the details?

We are currently looking for a Staff Machine Learning Engineer to lead at-scale high-performance ML Algorithms design and engineering in our Data Science organization. The ideal candidate will have a background in Computer Science, Applied Mathematics, Statistics, Operations Research or Engineering and is able to advise best practices of ML model development, deployment and lifecycle. Candidates are expected to have expertise in high-performance distributed systems, online/offline search and ranking, real-time computation and ML algorithms, cloud services such as AWS/GCP, and the ability to work with cross functional leadership teams within Groupon science and engineering organizations.

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 compelling place to work?

You’ll spend time on the following:

  • Advise, build and develop at-scale high-performing ML solutions that enhance Groupon’s strategies for optimizing engagement with customers and local businesses (merchants).

  • Show end-to-end ownership and leadership on complex ML projects from ideation to production. 

  • Designing a world-class system architecture; helping Groupon engineering and science teams to migrate existing on-perm systems to Infrastructure as a Service (IaaS) or Platform as a Service (PaaS) environment using AWS/GCP cloud technologies.

  • Working closely with product and engineering leadership teams; forming and establishing an ML based culture to improve Groupon business leveraging all aspects of AI/ML.

  • Interpreting and communicating insights and findings from analyses and experiments to product and business stakeholders.

  • Working with the broader science, product and engineering organizations to identify solutions and best practices that impact Groupon’s e-commerce business.

We’re excited about you if you have:

  • MS degree (PhD preferred) in Computer Science, Engineering, Applied Mathematics, Statistics, Operations Research, or related quantitative field.

  • 8+ years of work experience as an ML Engineer, Tech Lead, Data Scientist, Software Developer or a related role .

  • Proven ability to architect at-scale ML solutions to complex problems with a large customer base.

  • Experience in applying batch and online learning algorithms, search, ranking and core algorithm design.

  • Experience with widely-used (un)supervised, deep neural nets and machine learning algorithms.

  • Experience in NoSQL, Hadoop, ML packages (e.g, TensorFlow, CUDA, Pandas, Numpy).

  • Experience with AWS technologies and tools (e.g. S3, Redshift, SageMaker, Athena, Glue)

  • Ability to consolidate data from different sources, perform outlier detection, and conduct feature engineering tasks.

  • Proven experience with Spark, PySpark, or Scala is a plus.

We value individuals who are:

  • Customer-focused: We believe that doing what’s right for the customer is ultimately what will drive our business forward.

  • Obsessed with quality: Your production code just works & scales linearly

  • Team players. You believe that more can be achieved together. You listen to feedback and also provide supportive feedback to help others grow/improve.

  • Fast learners: We are willing to disrupt our existing business to trial new products and solutions. You love learning how to use new technologies and then rapidly apply them to new problems.

  • Pragmatic: We do things quickly to learn what our customers desire. You know when it’s appropriate to take shortcuts that don’t sacrifice quality or maintainability.

  • Owners: Engineers at Groupon know how to positively impact the business.
