Technical Lead governing AI data readiness and API gateways at Coupa, whose platform helps businesses optimize total spend. Defining safeguards for GenAI applications, data quality, compliance, and observability.
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
Benefits
- Top-tier health benefits and life insurance
- Long-term group savings with employer match using our Wealthsimple for Business platform
- 20 vacation days + 4 wellness days per year, and unlimited sick and mental health days
