You’ll make things happen–fast. Overview We are seeking a Principal Data Scientist to lead ZoomInfo's product analytics function and own our measurement systems across the product portfolio. This is a technical leadership role for someone who is fundamentally an exceptional analyst first - someone obsessed with understanding customer behavior through data, with the ability to influence strategy through insights. This role combines hands-on analytical depth with strategic scope. You'll design measurement frameworks, conduct deep-dive investigations, and drive product decisions through data. While we're particularly interested in candidates with PLG experience, what matters most is your ability to rapidly understand any product domain, ask the right questions, and uncover insights that shape business outcomes. The ideal candidate is an analytically relentless someone who writes clean SQL, thinks statistically, debugs data problems obsessively, and translates findings into clear business narratives. You're comfortable in ambiguity, own investigations from scratch, and build scalable analytical systems. Leadership here means elevating analytical standards and being a trusted data partner to Product, Engineering, and business teams. What You'll Do Product Measurement & Analytics Architecture Design and own measurement frameworks that connect customer behavior to business outcomes (activation, adoption, monetization, retention, expansion, churn) Establish source-of-truth definitions for key metrics and KPIs across product lines Build scalable reporting infrastructure and dashboarding systems that minimize manual overhead Develop leading indicators that predict customer success and business impact Ensure measurement consistency and data quality across teams and business units Deep-Dive Investigation & Diagnostics Conduct rigorous root-cause analyses on significant changes in product performance or business metrics Investigate customer behavior patterns, friction points, and conversion barriers across the customer journey Build customer segmentation frameworks that reveal behavioral differences and predict outcomes Identify the behaviors and product experiences most strongly associated with customer success Translate complex analyses into clear business narratives that shape decisions Growth & Product Insights Quantify opportunity size and identify high-leverage areas for product investment Support experimentation efforts by designing test frameworks and evaluating results with statistical rigor Build analytical frameworks that help teams prioritize investments across the customer lifecycle Advise Product and GTM leadership on customer trends, adoption patterns, and growth opportunities Measure business impact of major product initiatives and roadmap decisions AI-Native Analytics & Operational Excellence Redesign analytics workflows to leverage AI tools (Claude, automation, etc.) for faster investigation and scaled insights Build systems that continuously monitor product performance and surface anomalies proactively Develop scalable self-service analytics capabilities while maintaining data governance and trust Establish workflows that reduce manual effort and increase speed-to-insight Stay current with emerging AI capabilities and incorporate them into your analytical toolkit Cross-Functional Leadership Partner with Product, Engineering, GTM, and executive teams as a trusted data advisor Elevate analytical standards and build a culture of rigorous, data-informed decision-making Lead initiatives from opportunity identification through execution and impact measurement Influence senior stakeholders through data storytelling and clear business context About You You think in systems and causality, not just dashboards - you ask "why" until you understand the mechanism You're intellectually restless about data quality and will debug a data pipeline issue as readily as conducting analysis You're curious about how products drive customer adoption, monetization, and retention You balance technical depth with business judgment and stakeholder communication You enjoy the full arc: framing ambiguous problems, designing investigations, executing analysis, and translating findings into action You actively use analytical tools and automation (including AI) to scale your impact and accelerate insights What You Bring 8+ years of experience in Product Analytics, Growth Analytics, Data Science, or related analytical fields Expert-level SQL and Python skills - you write clean, efficient code and debug data issues independently Strong statistical foundation - you understand experimental design, significance testing, and know when correlations mislead Demonstrated ability to lead large-scale analytical initiatives with measurable business impact Deep experience conducting investigations into customer behavior, product performance, and business outcomes Ability to translate complex data into clear, actionable business recommendations and influence decisions Project management discipline - you own scope, prioritize ruthlessly, and ship insights that drive action Strong fundamentals in building scalable systems - reporting infrastructure, monitoring, data pipelines, dashboards Preferred Qualifications Experience in Product-Led Growth or self-serve SaaS (Figma, Notion, Slack, Linear, Calendly, etc.) - you understand activation loops and freemium economics SaaS customer lifecycle analytics - you can map the full journey from trial to expansion Proficiency with analytics stack - (data warehousing, BI tools, SQL, Python) Experience leveraging AI tools to improve analytical workflows and reduce manual effort Background in Statistics, Mathematics, or Computer Science Success in This Role Means ZoomInfo has clear, consistent measurement frameworks that connect customer behavior to business outcomes Product and business leaders understand the drivers of customer adoption, retention, and growth Growth opportunities and performance risks are identified proactively through continuous monitoring Product investments are prioritized using rigorous analysis of customer impact and business value Analytics workflows are increasingly automated and scaled through AI-enabled processes Teams view analytics as a strategic partner that shapes decisions, not just a reporting function You've identified and onboarded high-leverage growth opportunities and driven measurable business impact Why This Role is Different This isn't a traditional reporting or dashboard role. You're hands-on, technically deep, and leading through the quality and impact of your analysis. Your scope is broad, you have freedom to explore the entire product and customer journey but your success is measured by the rigor of your investigations and the business impact of your insights. If you find yourself most energized by finding a data bug, designing a clean statistical test, or discovering a behavioral insight that reframes how the company thinks about a customer problem, this is your role.

ZoomInfo is where careers accelerate. We move fast, think boldly, and empower you to do the best work of your life. You’ll be surrounded by teammates who care deeply, challenge each other, and celebrate wins. With tools that amplify your impact and a culture that backs your ambition, you won’t just contribute. You’ll make things happen–fast. You'll set the technical direction for the intelligence layer every ZoomInfo AI agent reasons over — what's true about companies and the people in them, how they relate, and what they're buying. As a senior individual contributor with no direct reports, you will own strategy across the data graph, entity resolution, and buying intent, staying hands-on in the hardest of these problems. You'll decide when classical machine learning, statistics, or language models is the right tool, and turn good judgment into standards other teams adopt. What You'll Do You will set technical strategy for the data graph, entity resolution, buying intent, and agent context, deciding which problems to take on, in what order, and how the pieces connect. You will frame and ship problems nobody has framed yet, such as extraction for companies with no public footprint or semantic intent at web scale, deciding what not to build as deliberately as what to build. You will define evaluation standards that other teams adopt, including sampling methodology, human labels, validated LLM judges, and release gates, and know where each one breaks. You will define the data contracts between the data graph, intent signals, and the agents that consume them, including agent memory, keeping the system cost-effective to run across the full dataset. You will turn good choices into defaults across the group: the baseline every model must beat, how uncertainty is reported, and which metrics get retired when they mislead. You will lead design reviews, mentor senior engineers, shape hiring, and represent the team's technical judgment to product and leadership. What You Bring Must-Have: You have set technical direction as an individual contributor for a problem area spanning more than one team, with the resulting machine learning systems in production and owned after launch — depth of impact matters more than years or past titles. You bring breadth across classical machine learning on large, messy tabular data, applied statistics, language processing at scale, and LLM agents or multi-step systems, with recognized depth in at least one. You have defined and driven adoption of evaluation standards beyond your own team for systems with no single right answer, including LLM judges validated against human labels and results reported with their limits. You have a track record of changing how a group builds or measures — for example, introducing a baseline or review practice that other teams now use. You have made cost and capacity decisions for model training and serving, including when to self-host, distill, or call a hosted model, with cost tracked per unit of work. You are hands-on in production Python and strong SQL with distributed data processing experience, and you use AI coding tools daily with rigorous review of their output. Preferred: You have experience with ranking and retrieval, including embeddings, learned re-ranking, and metrics such as recall@k, MRR, and nDCG. You bring entity resolution, knowledge graph, or web-scale information extraction experience on messy, real-world data. You have trained and served open-weight models in PyTorch or an equivalent framework, including GPU capacity planning. You have built user memory or context systems for agents, or defended LLM systems against adversarial inputs and prompt injection. #LI-Remote #LI-VC1 Actual compensation offered will be based on factors such as the candidate’s work location, qualifications, skills, experience and/or training.

You’ll make things happen–fast. You'll help build the intelligence every ZoomInfo AI agent reasons over — what's true about companies and the people in them, how they relate, and what they're buying. You'll own outcomes end to end, from the data a model learns from to the product surface where its output lands, applying classical machine learning, statistics, or language models based on what the problem calls for. You'll take a problem in the data graph, entity resolution, or buying intent from design through production, and own it after launch. What You'll Do You will extract leadership, locations, and products from the websites of companies with almost no public footprint, and detect stale records, choosing which pages to read based on cost per document. You will estimate headcount and revenue for companies with sparse public information, using gradient-boosted trees, regression with missing inputs, and calibrated uncertainty. You will determine whether two records describe the same company or person, measuring both false merges and false splits. You will infer buying intent from the meaning of what companies read, not keyword matches, across large volumes of multilingual, noisy text, feeding propensity scoring, lookalike retrieval, and contact recommendations. You will build research agents that cite their sources, along with the evaluation systems behind them: human labels, validated LLM judges, and regression gates. You will train small, task-specific models distilled from larger ones, measuring them against the larger model rather than against perfection, and own their quantization and serving. You will take a problem from design to production and own it after launch, including its evaluation and its cost, while helping other engineers improve their work through design and code review. What You Bring Must-Have: You have taken machine learning systems to production and owned them after launch, following the outcome into whichever layer it needs — depth matters more than years. You bring classical machine learning expertise beyond language models, including supervised learning and feature engineering on large, messy tabular data, along with applied statistics: experiment design, statistical inference, and calibrated scores under class imbalance. You have deployed language processing at scale — text classification, information extraction, and entity linking over large volumes of multilingual, noisy text. You have built LLM agents or multi-step systems in production, including tool and context design and failure analysis from traces, and you've evaluated systems with no single right answer using LLM judges validated against human labels. You are proficient in production Python and strong in SQL, with experience in distributed data processing, and you use AI coding tools daily, rigorously reviewing their output. Preferred: You have experience with ranking and retrieval, including embeddings, learned re-ranking, and metrics such as recall@k, MRR, and nDCG. You bring experience in propensity modeling, clustering, or entity resolution on messy, real-world data. You have trained and served open-weight models in PyTorch or an equivalent framework, with cost tracked per unit of work. You have defended LLM systems against adversarial inputs and prompt injection, or worked on web-scale information extraction, knowledge graphs, or user memory for agents. #LI-Remote #LI-VC1 Actual compensation offered will be based on factors such as the candidate’s work location, qualifications, skills, experience and/or training.
