Trusted by brands like Instacart, Western Union, NBCUniversal, ZocDoc, and Sephora, we’re big enough to matter, small enough for you to make a real impact. If you’re excited by the grit of building, rapid learning, and shaping the future of customer growth, you’ll find your place here. The Discovery team is at the forefront of driving Branch’s success in the mobile growth and advertising ecosystem. Our mission is to intelligently connect the right ads to the right users at the optimal moment, maximizing brand awareness and return on ad spend (ROAS) for our customers while ensuring a high-quality user experience. As a Senior Data Scientist on this team, you will be instrumental in building the next generation of our ad delivery platform. You will develop, productionize, and deploy sophisticated machine learning models that are essential for optimizing ad delivery performance through novel sourcing and targeting techniques. This role requires a blend of rigorous scientific research, engineering execution, and deep understanding of the Ad Tech domain.

Requirements

4+ years of professional experience building and deploying machine learning models for business applications.
PhD in Computer Science, Engineering, Machine Learning, Statistics, or a related quantitative field, OR a Master's degree in a related field and 4+ years of relevant experience.
Strong programming proficiency in one or more relevant languages (e.g., Python, Java, C++).
Deep expertise in foundational computer science areas, including algorithms and data structures, numerical optimization, data mining, and distributed computing (e.g., Spark, Hadoop).

Prior experience developing models specifically for recommender systems, personalization, or large-scale optimization problems.
Familiarity with cloud computing environments (AWS, GCP, or Azure).

Responsibilities

Lead the design, development, and deployment of high-impact machine learning models (e.g., predicted click-through rate, conversion rate, bidding optimization, and lookalike targeting) directly into our production environment.
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.
Communicate complex findings and product vision to engineers, product managers, and business stakeholders, influencing the roadmap for the Discovery platform.
