Senior Data Scientist

Job Description:

Who We Are!  

Pollfish, a Prodege, LLC company, is an online market research survey platform where data driven brands bring market research in-house for faster and smarter decision making. We have a proprietary network of 250M consumers/year which enables companies to connect with and understand real consumers worldwide in a fast, easy and cost-effective way.

Strategic Imperative: 

The Sr. Data Scientist is responsible for producing actionable insights to drive decision-making across the business through rigorous analysis, experimentation, and business-focused data science. This role applies statistical methods, ML modeling, and behavioral analysis to quantify user behavior, optimize lifecycle marketing, evaluate product and monetization strategies, and inform business decisions. The role will closely collaborate with business stakeholders to translate business problems and data into solutions.

This position is centered on hands-on analytics, experimentation, and business impact. While the role will involve building predictive models, it is not focused on the deployment of live production models or ML Ops. The role is intended to incorporate AI agents to continuously improve and automate analytical processes

Primary Objectives:

• Data Analysis & Insights Development: Drive data-informed progress across priority business areas by delivering rigorous analysis, actionable insights, and close partnership on optimization initiatives.

• User Intelligence, Segmentation & Marketing Enablement: Develop and operationalize user-level insights, segmentation frameworks, and behavioral analysis that enable smarter targeting, personalization, and lifecycle engagement across growth and marketing programs.

• Experimentation, Learning & Strategic Insight: Enable confident decision-making through statistically sound experimentation, structured insight generation, and systematic documentation of learnings to inform business planning, long-term strategy, and continuous improvement.

Qualifications - To perform this job successfully, an individual must be able to perform each job duty satisfactorily.

  • Partner with teams on hypotheses, success metrics, and post-test actions.

  • Own the capture and scaling of learnings to improve future experimentation.

• Data Foundations Support

  • Partner with Analytics Engineering to define canonical and semantic models and other business data requirements necessary to support a well functioning Data Science discipline.

  • Enable reliable lifecycle tracking and feature generation.

  • Partner with AI teams to translate workflows and recurring analytical patterns into agentic analytics systems that scale insight generation.

What does SUCCESS look like?

Success in this role is demonstrated by consistently translating data into clear, actionable decisions that improve product performance, lifecycle marketing effectiveness, and monetization outcomes. This is reflected in well-designed experiments and frameworks that drive confident business choices, analytical insights that meaningfully influence strategy, and strong partnerships with Analytics Engineering and Machine Learning through precise data definitions and feature guidance. Over time, success is evident in a growing body of documented learnings, trusted metrics, and a measurable impact on how the organization tests, learns, and optimizes.
