Job summary

Customer.io is seeking a Senior Data Scientist to partner with Product, Marketing, and Customer Experience to evaluate changes, design experiments, and turn data into actionable direction. You will build models, analyze behavior, and apply ML pragmatically to support product and business decisions.

We value ownership, curiosity, analytical rigor, clear communication, and collaborative problem-solving as we shape data science within a growing SaaS organization.

Qualifications

• 5+ years of experience in a Data Science role within B2B SaaS or a similar product- or growth-focused environment.
• Proficiency in SQL and Python for large-scale analysis, modeling, and exploration.
• Experience with modern cloud data platforms (Snowflake, BigQuery, or similar); familiarity with dbt is a plus.
• Strong communication and stakeholder skills - you can explain complex analysis clearly to PMs, marketers, executives, and non-technical partners.
• An ownership mindset - you help define the problem and move work forward; you don’t wait for perfect requirements.

Responsibilities

• Analyze behavioral patterns across the customer lifecycle to identify trends, usage archetypes, and opportunities to improve adoption, engagement, and retention.
• Design experiments and measurement approaches to evaluate the impact of product and marketing changes - and help teams make decisions based on evidence rather than intuition.
• Build models and datasets that improve how teams segment customers, forecast outcomes, and identify trends.
• Apply machine learning and AI techniques where they solve practical problems, for both internal decision-making and customer-facing scenarios.
• Partner with Data Engineering to improve the quality, reliability, and accessibility of core data and metrics.
• Communicate findings clearly and directly so teams can make informed decisions without needing a statistics background.
