- Drive complex, ambiguous, and high-scale ML projects from initial research and proof-of-concept through to large-scale deployment, working closely with software engineering teams.
- Design and execute rigorous online A/B experiments to test hypotheses, measure model performance, and statistically analyze results to drive continuous product improvement.
- Perform hands-on analysis and modeling of enormous, complex data sets to identify predictive signals and develop new features that enhance targeting and sourcing efficacy.
- Establish scalable, efficient, and automated processes for large-scale data analysis, machine learning model development, validation, and serving.
- Stay abreast of the latest research in ML, deep learning, optimization, and Ad Tech, and apply new, innovative approaches to Branch’s unique challenges in ad delivery and optimization.
