Staff Data Scientist leading strategy and execution for marketing intelligence efforts at Reddit. Focus on optimizing marketing spend and measuring effectiveness for long - term growth.
About the role
- Senior Data Scientist optimizing marketing data at Wealthsimple, the largest fintech in Canada. Building data products and algorithms to inform business decisions and drive growth.
Responsibilities
- Build data products and algorithms that optimize marketing performance—including budget allocation, targeting strategies, and campaign optimization across multiple channels.
- Design and implement measurement strategies for marketing initiatives, including attribution modeling, incrementality analysis, and multi-touch attribution.
- Drive marketing strategy through data insights, A/B testing, and causal inference methodologies to maximize ROI on marketing spend.
- Develop and maintain analytics pipelines and data infrastructure, working collaboratively with data engineers and other data scientists.
- Conduct exploratory analysis to identify growth opportunities, understand customer behavior, and optimize marketing tactics.
- Provide business-as-usual analytics support including reporting, dashboards, and ad-hoc analysis for marketing stakeholders.
- Leverage AI tooling to handle operational tasks efficiently and focus your expertise on high-impact strategic problems.
- Partner with ad platforms (Google, Meta, etc.) and internal engineering teams to ensure robust tracking, data integration, and measurement capabilities.
- Take ownership and ship it—continuously look for the simplest, most effective way to approach challenges; Occam's razor is your friend.
- Work where you are (while our Canadian offices are located in Toronto, we are a remote-first workforce and you can join from anywhere in Canada!)
Requirements
- Strong preference for prior experience working with marketing teams and paid advertising platforms (Google Ads, Meta Ads, programmatic advertising, etc.)
- Understanding of digital marketing mechanics including attribution, ad platforms, tracking, and conversion optimization.
- Strong technical skills in Python and SQL with experience building production-quality code.
- Experience with measurement and attribution—ideally including building in-house attribution systems (not just using off-the-shelf tools like Google Analytics).
- Proven track record in algorithm development, optimization problems, or building data-driven decision systems.
- Strong foundation in causal inference, A/B testing, and experimental design.
- Excellent communication skills and ability to translate complex technical concepts for non-technical stakeholders
