This is not primarily a reporting role-the focus is understanding what is happening, why, and what we should do about it.\nWhat You'll Do\nAnalyze performance across campaigns, inventory, audiences, bidding, models, and conversions.\nMonitor and investigate CPA, CPC, CTR, VCR, ROAS, spend, delivery, and revenue.\nProactively detect performance anomalies and optimization opportunities.\nPerform root-cause analysis across models, inventory, identity, attribution, audience, and data quality.\nDesign and analyze A/B tests and experiments.\nBuild reusable SQL/Python analyses, metrics, and automated diagnostics.\nPartner with Engineering and Trading to turn insights into measurable improvements.\nConvert recurring investigations into AI-assisted troubleshooting and automation.\nWe'd Love for You to Have\nStrong SQL and Python skills with experience analyzing large-scale datasets.\nStrong analytical, statistical, and experimentation fundamentals.\nExperience with platforms such as Snowflake, Spark, Trino, Databricks, or BigQuery.\nUnderstanding of data pipelines, data modeling, and data quality.\nStrong problem-solving and communication skills.\nAdTech, marketplace, recommendation, or high-scale platform experience preferred.\nExperience with RTB, bidding, attribution, campaign optimization, or ML-driven systems is a strong plus.\nQualifications: \nBachelor's degree in Engineering (CS/IT) or an equivalent degree from a well-known institute or university; advanced degree is a plus but not required given depth of experience.\nWhat Success Looks Like\nDetect earlier → Diagnose faster → Recommend action → Automate\nThe goal is not more dashboards. The goal is to create a performance intelligence capability that improves campaign outcomes, reduces investigation time, guides Engineering/Trading decisions, and becomes the foundation for AI-native troubleshooting.\nAI-Enabled Engineering Mindset:\nWe value engineers who actively leverage Generative AI tools and IDEs (e.g. GitHub Copilot, ChatGPT, Claude, Cursor, Windsurf etc.) to accelerate development, improve code quality, automate repetitive tasks, and enhance documentation and debugging workflows. Engineers who demonstrate AI-first thinking using these tools to drive faster experimentation, ideation, and technical execution will thrive in our high-scale, performance-critical environment.\nAdditional Information:\nReturn to Office: PubMatic employees throughout the global have returned to our offices via a hybrid work schedule (3 days “in office” and 2 days “working remotely”) that is intended to maximize collaboration, innovation, and productivity among teams and across functions.\nBenefits: Our benefits package includes the best of what leading organizations provide, such as paternity/maternity leave, healthcare insurance, broadband reimbursement.
