At Klaviyo, we build products that empower businesses to create stronger, more personalized relationships with their customers. We help businesses leverage data to deepen their customer relationships, foster growth and drive business outcomes. We are looking for a visionary Head of Product Analytics and Customer Insight to join our dynamic team, enhance our analytic capabilities and drive our customer strategy.
We’re looking for someone who thrives at the intersection of data science and product development — someone who pairs deep statistical rigor with product intuition, and can fluidly move between building complex models in R or Python and advising product leaders and executives on strategic decisions. You should be just as comfortable designing and validating a causal inference framework as you are communicating its implications to stakeholders across the company. Please note that this is a hybrid role and requires 3 days/week in our Boston office. Fully remote candidates will not be considered at this time.

WHAT YOU’LL DO:

• Partner with product and engineering teams to identify and evaluate high-impact product opportunities through rigorous experimentation, causal inference, and predictive modeling
• Lead the design, implementation, and analysis of experiments — including A/B tests and multivariate tests — ensuring sufficient power, correct statistical methods, and actionable recommendations
• Conduct statistical research projects to uncover patterns in customer behavior, evaluate product performance, and identify causal relationships — using methods such as Mixed Effects Models, Difference-in-Differences, clustering algorithms, and time series analysis to guide product strategy and decision-making.
• Define the right product and customer metrics to measure success, and build scalable, self-serve analytics tools and dashboards that enable product managers and cross-functional stakeholders to make data-informed decisions independently.
• Collaborate with data engineering to define and implement reliable data pipelines and DBT models that ensure clean, well-structured, and trustworthy data for downstream analysis and self-serve use.
• Communicate insights clearly and persuasively to cross-functional stakeholders, from product teams to executive leadership

WHY YOU’LL LOVE THIS ROLE

• Influence the direction of a high-impact product area and help define how success is measured
• Work alongside a world-class data team where experimentation and modeling are first-class tools
• Join a company where data science is embedded in the product development lifecycle, not siloed as reporting support
• Be part of a culture that values intellectual rigor, collaborative problem-solving, and continuous learning
