Apply sophisticated quantitative methods — including machine learning, causal inference, synthetic controls, difference-in-differences, and propensity score matching — to answer complex business questions with statistical rigor.
Build and own robust customer segmentation frameworks that reveal behaviorally distinct consumer cohorts, and translate those insights into concrete, segment-specific growth strategies.
Analyze how consumer behavior evolves across PayPal’s full product ecosystem, quantifying the impact of cross-product attachment on engagement, retention, and monetization.
Monitor key consumer funnel metrics — activation, engagement, retention, and monetization — across products, segments, and geographies, and explain drivers of change with speed and precision.
Proactively surface new growth and optimization opportunities through analytics and financial modelling, developing rigorous business cases that quantify opportunity size and expected impact.
Manage analytical projects end-to-end, from inception through delivery, ensuring quality, timeliness, and relevance to business objectives.
Partner closely with Commercial, Product, Marketing, and Finance teams to inform and influence strategy, serving as a trusted analytical advisor to senior stakeholders.
Leverage AI-native tools such as Claude and Claude Code to accelerate analysis, automate recurring workflows, and scale insight delivery across the consumer growth domain.

About the Company

PayPal has been revolutionizing commerce globally for more than 25 years.
Creating innovative experiences that make moving money, selling, and shopping simple, personalized, and secure, PayPal empowers consumers and businesses in approximately 200 markets to join and thrive in the global economy.
We operate a global, two-sided network at scale that connects hundreds of millions of merchants and consumers.
We help merchants and consumers connect, transact, and complete payments, whether they are online or in person.
PayPal is more than a connection to third-party payment networks.
We provide proprietary payment solutions accepted by merchants that enable the completion of payments on our platform on behalf of our customers.
We offer our customers the flexibility to use their accounts to purchase and receive payments for goods and services, as well as the ability to transfer and withdraw funds.
We enable consumers to exchange funds more safely with merchants using a variety of funding sources, which may include a bank account, a PayPal or Venmo account balance, PayPal and Venmo branded credit products, a credit card, a debit card, certain cryptocurrencies, or other stored value products such as gift cards, and eligible credit card rewards.
Our PayPal, Venmo, and Xoom products also make it safer and simpler for friends and family to transfer funds to each other.
We offer merchants an end-to-end payments solution that provides authorization and settlement capabilities, as well as instant access to funds and payouts.
We also help merchants connect with their customers, process exchanges and returns, and manage risk.
We enable consumers to engage in cross-border shopping and merchants to extend their global reach while reducing the complexity and friction involved in enabling cross-border trade.
Our beliefs are the foundation for how we conduct business every day. We live each day guided by our core values of Inclusion, Innovation, Collaboration, and Wellness.
Together, our values ensure that we work together as one global team with our customers at the center of everything we do – and they push us to ensure we take care of ourselves, each other, and our communities.
Our Consumer Portfolio Growth team sits at the intersection of data science and commercial strategy.
We focus on understanding how consumers engage across PayPal’s full product suite — spanning PayPal P2P, Checkout, Credit, Debit, and more — and on identifying where the greatest untapped growth opportunities lie.
The team drives business outcomes through advanced analytics, customer segmentation, funnel analysis, and causal inference.
We are a close-knit group of intellectually curious, technically rigorous data scientists who take pride in delivering crystal-clear narratives to senior leadership and measurable impact to the business.
We are committed to building an equitable and inclusive global economy.
We strive to create a flexible, balanced work culture with a holistic approach to benefits.
We are proud to have a diverse workforce reflective of the merchants, consumers, and communities that we serve, and we continue to take tangible actions to cultivate inclusivity and belonging at PayPal.
PayPal is on a mission to revolutionize commerce globally.
We’re driving our company, industry, and society forward with vision and velocity.
With our commitment to excellence, innovation, and talent, the possibilities are limitless.
