Job description
The Role
The Data Science team at Block turns unique customer and product data into decisions that expand access to financial services. Our Lending team powers the decisioning behind Cash App Borrow, Afterpay, Square Loans, and the next generation of first‑party credit products. We’re looking for a Product Data Scientist to build, measure, and improve credit products that serve customers that traditional credit systems often miss. You’ll partner closely with product, engineering, and risk teams to define metrics, evaluate experiments, understand customer behavior, and turn ambiguous product questions into clear decisions.
This is an agentic data science role. You’ll use AI tools and agent workflows to move faster and think more rigorously across the full data science loop: exploring messy datasets, building pipelines, stress‑testing hypotheses, evaluating product changes, and turning analysis into decisions.
You Will
Turn complex product, customer, and risk data into clear insights, decision frameworks, and durable measurement systems for product, risk, and business partners
Use AI tools and agent workflows to improve both the speed and quality of analytical work, from accelerating exploration and automating repetitive tasks to generating hypotheses and stress‑testing conclusions
Own end‑to‑end execution across analysis, metrics definition, experimentation, forecasting, visualization, and decision support
Define and maintain measurement frameworks for credit products, including customer eligibility, repayment behavior, product usage, loss performance, funnel health, and long‑term customer outcomes
Partner with risk teams to evaluate model and policy performance, monitor cohorts, identify bias or drift, and connect risk decisions to product and business impact
Design and analyze experiments, rollouts, and policy changes that shape customer access, repayment outcomes, and product growth
Approach ambiguous product and risk questions from first principles, using statistical judgment to define the right cohorts, metrics, and decision criteria
Communicate insights clearly to technical, product, and business stakeholders, including risk partners and senior decision‑makers
Lead technical direction and standards for the Block Data Science team – making and building consensus on key technical decisions, and creating reusable frameworks, measurement templates, and scalable tooling that remove complexity for others
Drive localized cross‑team impact by connecting measurement and insights across Lending products (Borrow, Afterpay, Square Loans) and partnering with senior stakeholders in product, engineering, and risk to align Data Science work with broader strategy
Mentor and grow the team by developing junior data scientists, fostering a culture of analytical rigor and psychological safety, and contributing to hiring through interviews and calibrations
You Have
A bachelor’s degree in statistics, data science, economics, computer science, or a similar quantitative field with 12+ years of experience in a relevant role
A graduate degree in statistics, data science, economics, computer science, or a similar quantitative field with 6-8+ years of experience in a relevant role
Advanced proficiency with SQL and experience building clear, decision‑oriented data visualizations
Strong product, analytical, and statistical judgment, including the ability to turn ambiguous product, customer, or risk questions into sound analyses, communicate tradeoffs clearly, and support decisions
Experience using AI tools to improve the speed, quality, and durability of analytical work
