The team focuses on ClickThrough Rate (CTR) prediction to optimize ad engagement and marketplace efficiency particularly for Reddits most critical ad product: CPC (CostPerClick). Additionally the team manages video view modeling landing page optimization and pCTR (predicted CTR) models for product ads.
The Engagement Modeling team collaborates closely with both upstream and downstream teams to drive the development of new features and model iterations continually improving ranking models for upper and middle funnel products.
Project highlights:
- Model Architecture Engineering: Explore and implement stateoftheart architectures such as multitask learning and calibration models.
- Systematic Feature Engineering: Develop powerful features from Reddits data using techniques like aggregation embedding submodels and content understanding.
- ZerotoOne Model Development: Build models from scratch collaborating with crossfunctional teams on GoToMarket strategies for vertical products like video view models landing page optimization and product ads.
As a Senior Machine Learning Engineer on the Engagement Modeling team you will be responsible for researching formulating and executing projects while actively contributing to the endtoend implementation process. You will work closely with crossfunctional teams to ensure the successful delivery of products.
