Staff Software Engineer, Machine Learning (Prediction)

Reddit is continuing to grow our teams with the best talent. This role is completely remote friendly and will continue to be after the pandemic. 

We’re evolving and continuing our mission to bring community, belonging, and empowerment to everyone in the world. Providing a delightful and relevant experience to our users applies to our Ads like all of our offerings, and we’re excited to build a product that is best-in-class for our users and advertisers. The year ahead is a busy one - join us!

Ads prediction team is the central team to handle machine learning needs in the ads delivery pipeline.   Some examples projects that the team own:

  • Improve our model through systematic model architecture engineering work including exploring different deep neural network architectures
  • Systematic feature engineering work to build power features from Reddit’s data with aggregation, embedding, content understanding techniques
  • Developing highly efficient retrieval ranking models with good balance between model performance and computation efficiency 

As a Staff Machine Learning Engineer in the ads prediction team, you will research, formulate and execute on our mission to deliver the right ad to the right user under the right context with data and ML driven solutions.

Responsibilities:

  • Building industrial level models for critical ML tasks with advanced modeling techniques
  • Research, implement, test, and launch new model architectures including deep neural networks with advanced pooling and feature interaction architectures
  • Research, implement, test, and launch new model architectures to handle retrieval ranking tasks with a good balance between model performance and computation efficiency
  • Systematic feature engineering works to convert all kinds of raw data in Reddit (dense & sparse, behavior & content, etc) into features with various FE technologies such as aggregation, embedding, sub models, etc.  
  • Be a mentor and cross-functional advocate for the team
  • Contribute meaningfully to team strategy. We give everyone a seat at the table and encourage active participation in planning for the future.

Required Qualifications:

  • 2+ years of experience with industry-level deep learning models
