Data Science Senior Associate - Marketing Analytics

You will join a collaborative team that applies advanced modeling, machine learning, and applied AI to profile clients across all lines of business, improve customer experience, and enable business performance at scale. You will take on the toughest analytical challenges the team faces—from customer segmentation to digital marketing to AI-enabled and agentic alert systems—and turn them around with speed and rigor. You will work on high-visibility initiatives, partner closely with business and technology teams, and help move ideas from concept into implemented solutions embedded in day-to-day workflows. You will also have opportunities to grow through mentoring, training, and mobility.

As a Data Scientist Associate Senior at JPMorganChase within the Consumer & Community Banking Data and Analytics organization, you will operate as a senior technical contributor and force-multiplier for the team. You will independently own end-to-end modeling solutions—framing ambiguous problems, building and validating models, and driving them into production—while helping set technical direction and elevating the work of others. You will ensure solutions are statistically sound, aligned to business objectives, delivered quickly, and integrated into business processes to drive adoption and measurable impact.

Job responsibilities

• Own the team's highest-priority modeling problems end to end, framing ambiguous questions and delivering rigorous solutions on tight timelines
• Design, build, validate, and deploy advanced models spanning customer segmentation, digital marketing, and AI-enabled and agentic alert systems
• Translate business objectives into well-scoped modeling problems with clear success criteria and measurable outcomes
• Apply machine learning, statistical, and mathematical methods to develop novel solutions—including unsupervised methods such as PCA and k-means, supervised methods such as regression, tree-based models, and gradient-boosted algorithms, as well as causal inference, forecasting, and simulations
• Build applied AI and agentic solutions, including large language model-based systems, prompt engineering, and developer and AI assistants
• Serve as a technical lead on complex workstreams, helping direct and prioritize team efforts and unblocking others
• Communicate results, insights, and recommendations clearly to business stakeholders, technology partners, and senior leadership
• Partner with data science, engineering, product, and design teams to ensure solutions are feasible, scalable, and production-ready
