As a company, Reddit primarily generates revenue through advertising, and we're working towards building a massive business to fund our mission. We distinguish ourselves from other digital ad platforms by attracting advertisers who want to connect with a specific target audience because of our passionate and engaged communities.
The Ads Ranking organization is responsible for predicting various ad engagement rates, including but not limited to click, conversion, and app install predictions. These rates are then used in the ad auction to maximize ad engagements and marketplace efficiency. This organization owns a critical piece in the ads delivery pipeline and machine learning infrastructure.
Project highlights:
- Model architecture engineering via exploring different state-of-the-art model architectures such as Multi-task learning, Attention Layers, and Delayed Feedback models.
- Systematic feature engineering to build powerful features from Reddit’s data with aggregation, embedding, sub-models, content understanding techniques, etc.
- Build efficient ML infrastructure and tools such as auto ML flows and batch feature engineering framework to accelerate MLE dev cycle.
As a machine learning engineer in the Ads Ranking organization, you will research, formulate, and execute projects, and actively participate in the end-to-end implementation process. You will collaborate with cross-functional teams to ensure successful product delivery. You will also be able to contribute your expertise and shape the future of ads ML at Reddit.
