About the Role

As a Marketing Data Scientist II at Thumbtack, you’ll be expected to leverage your analytical expertise, marketing knowledge, communication and collaboration skills to drive a variety of high-impact projects. You will embed directly with the paid marketing team to help optimize various marketing channels, drive personalization and discover new channels. Outside growth marketing work, you’ll contribute to our broader Data Science team and company data culture by sharing your learnings, partnering with others, and building new capabilities for how we can use data to guide decisions.

• Translate ambiguous business questions into rigorous analyses and clear recommendations that improve individual campaign performance and optimize the overall marketing channel mix
• Design, execute, and interpret experiments and quasi-experiments to enable causal inference and inform high-stakes marketing investment decisions
• Partner closely with MarTech, Product Management, and Engineering to scope, build, and evaluate new capabilities—such as developing local market intelligence framework and improvements to customer LTV bidding systems—ensuring measurable performance gains
• Develop deep domain expertise in growth marketing measurement, experimentation, customer segmentation, and targeting optimization, and apply that expertise to influence strategy and execution
• Collaborate with cross-functional partners to build scalable analytical solutions, tools, and frameworks that unlock sustained growth
• Raise the bar for Thumbtack’s data culture by designing, maintaining, and documenting high-quality, trusted data tables and metrics that enable self-serve decision-making across teams

In order to be successful, you must bring

• A passion for problem-solving and critical thinking, with the ability to navigate ambiguity and turn data into clear, actionable insights
• Strong business judgment and the ability to identify signal in noisy, imperfect data
• Excellent communicator and compelling storyteller, with the ability to listen deeply, explain complex concepts clearly, and influence cross-functional partners
