The Growth Product Data Science team consists of data scientists with diverse educational backgrounds. Our team is responsible for leading data science initiatives across the global client experience – partnering with Consolidation, Product Marketing, Lifecycle Marketing, and Product Engagement to deliver quantitative insights, personalization, and predictive models that directly shape Wealthsimple's growth strategy.
We are a full-stack data science team, meaning we own the end-to-end lifecycle: data modeling, dashboards, predictive models, experiment design and analysis, ad-hoc analysis, and opportunity identification. We operate as consultative partners to our stakeholders – solving problems, identifying opportunities, and owning targeting – not executing tasks. We measure our success by the dollar value we deliver, the ideas we surface that get prioritized, and the model-based solutions we ship that outperform the status quo.
This role will primarily partner with our Consolidation product team, which is focused on creating an incredible first 30-day experience for new clients and driving them to make Wealthsimple their primary financial relationship. The team's work spans onboarding, product-led consolidation, the Home experience, Tiers, and account discovery. With touchpoints across so many critical surfaces, you'll be uniquely positioned to have outsized impact across all of these areas.

• Be the dedicated data science partner to the Consolidation product team, owning the analytics and modeling that power product-led growth across onboarding, activation, and full consolidation.

• Design and analyze rigorous product experiments across the client journey, from first funding through to full asset consolidation, using A/B testing, non-inferiority tests, and other causal inference methods to measure the impact of product changes on key growth metrics.

• Partner with the team's Personalization DRIs to incorporate machine learning models, such as next-best-account recommendations and personalized value propositions, into product flows where they will deliver the highest impact to clients.

• Develop deep product analytics to understand how clients move through the consolidation funnel, linking external accounts, reaching their first $5k, adopting multiple products, and identify where the biggest opportunities exist to accelerate that journey.

• Create and maintain data models and dashboards that monitor consolidation KPIs (Premium+ conversion, registrant-to-funded rates, linking rates, activation milestones) with a focus on data quality, accessibility, and efficiency.

• Collaborate cross-functionally with Product, Engineering, Growth, and Lifecycle Marketing to translate analytical findings into product decisions and shipped features.

• Proactively identify and size growth opportunities by being closest to the data, and then partner with stakeholders to get those opportunities prioritized and executed.

• Build automation tools and pipelines that increase team efficiency and scalability.

• Contribute to the team's culture of learning and knowledge sharing. Teach and learn from your teammates, and help make others successful.

• Take ownership and ship iteratively; believe that simple is better and Occam's razor is your friend.

• 5+ years of experience in data science, decision science, or a similar quantitative role, including experience as the primary data scientist for a product domain or function.

• Strong product analytics skills. A deep experience understanding user funnels, activation metrics, and translating product usage data into actionable growth insights.

• Excellent stakeholder management and communication skills. Able to partner closely with product managers and present complex analytical findings to senior leadership.

• Curiosity and ownership: willing to dive deep into product strategies, business context, and data to surface insights proactively while handling ambiguity.

• Deep expertise in experimental design and causal inference (A/B testing, non-inferiority tests, factorial designs, power analysis, and related methods). This is core to the role.

• Strong technical skills in SQL and Python, with hands-on experience in data pipeline tools such as dbt and Airflow.

• Strong understanding of data visualization and analytics engineering principles.

• Results-driven mindset: comfortable keeping things as simple as possible to achieve product goals.

• Able to build and maintain multi-functional relationships with various teams across the business.

• Prior experience in growth, go-to-market, or product-led growth data science is a strong plus (but not essential).

• Experience in fintech or financial services is a plus.

• Experience mentoring or coaching junior data scientists is a plus.
