Data Scientist - Mobile App Performance

About the Role:

Own the data science function for Mobile App performance, working at the intersection of ML and programmatic advertising. This is a high-ownership, high-visibility role--both internally and with our customers.

What You'll Do:

Model  Development 

• Build signal enrichment pipelines leveraging contextual signals, behavioral data, and mobile attribution frameworks

• Develop production-grade predictive models based on event data (clicks, installs, in-app events, retention).

• Partner with GTM teams to translate metric frameworks into buyer-facing insights and predictive models

Drive Product Development 

• Conduct deep-dive analysis to influence product and engineering decisions: pull and query large datasets, extract valuable signals from noise, and produce actionable insights into how we can drive better outcomes for buyers and publishers

• Develop predictive modeling frameworks to quantify performance gains from product hypotheses before they ship — reducing decision latency and de-risking the roadmap

• Act as the senior data science voice in product discussions. Bring partner-level insight and analytical rigor to roadmap decisions.

Evaluate and Improve System Health

• Understand changes and drivers across PubMatic's mobile ecosystem: diagnose issues, identify structural inefficiencies, and track input/output metrics at each system component

• Work with product and engineering to define success metrics, design experiments, and evaluate new features before and after launch.

• Design experiment frameworks and causal inference methods that produce reliable, unbiased signals for product and business decisions

Who You Are:

Required

• 5+ years of hands-on data science experience, with a focus on ML model development, statistical inference, and production-grade analysis

• Deep fluency in Python and SQL; experience with large-scale data environments (Spark, Hadoop, Hive, or equivalent)

• Strong foundation in experimental design, hypothesis testing, regression modeling, and causal inference

• Experience with ML algorithms relevant to ranking, prediction, and optimization problems: gradient boosted trees, deep learning, k-means, and related methods

• Proven ability to extract actionable signals from noisy, high-volume datasets and communicate findings clearly

• Track record of owning projects end-to-end, from problem framing through to production impact

Strongly Preferred

• Experience in mobile advertising, programmatic, or ad tech

• Familiarity with mobile measurement and attribution or campaign performance optimization in mobile applications

• Background working alongside ML engineering or product teams on systems where the model is the product

• Advanced degree (Master's or PhD) in Statistics, Computer Science, Mathematics, or a related quantitative discipline
