About the team   The Data Cloud Acceleration team identifies gaps and opportunities across clients and business units, then moves quickly to deliver practical new capabilities. We often develop and deploy the first version of a model, workflow, dataset, or application in days or weeks, learn from real usage, and improve it iteratively.  We are business-minded technologists who care more about impact than technical novelty. We use sophisticated methods when the problem requires them and simpler approaches when they will deliver a better result faster. Our work should be predictable, demoable, trusted, reusable, measured, and amplified by AI.    About the role   The Senior Data Scientist will build models, analyses, and supporting ML components that improve business decisions, intelligence products, and client outcomes. You will independently own defined deliverables—from understanding the requirement and preparing the data through modeling, validation, documentation, and delivery.  This is a hands-on individual contributor role. You will work across varied revenue and intelligence initiatives, often in partnership with a Lead Data Scientist, application engineers, analysts, and business stakeholders. The right candidate can move quickly without sacrificing trustworthiness and knows how to balance statistical rigor with the practical needs of the business.    What you’ll do Own model and analysis deliverables. Take a defined business problem and independently deliver a reliable model, analysis component, scoring workflow, or supporting dataset.   Translate business questions into analytical approaches. Ask clarifying questions, understand how the output will be used, and recommend an approach that fits the decision, timeline, and available data.   Build and test models quickly. Develop practical solutions using statistical methods, machine learning, deep learning, or existing models and services where appropriate.   Prepare trustworthy data. Profile, cleanse, join, and validate noisy datasets while checking completeness, freshness, distributions, nulls, duplicates, and match rates.   Create repeatable scoring workflows. Move useful work beyond the notebook by building reusable Python components, batch-scoring processes, APIs, or lightweight services.   Evaluate results responsibly. Establish baselines, select appropriate metrics, perform statistical reasonableness checks, reconcile unexpected results, and clearly document limitations.   Support intelligence products and applications. Work with application and data teams to define the right data ingredients, test hypotheses, and integrate model outputs into usable experiences.   Add operational discipline. Include validation, monitoring, failure handling, refresh expectations, documentation, and a clear usage path in delivered work.   Use AI to improve your own productivity. Apply tools such as Claude, Codex, and similar assistants to accelerate coding, testing, research, debugging, and documentation while independently verifying the results.   Communicate progress early and clearly. Make milestones, assumptions, risks, dependencies, and issues visible rather than waiting until delivery.     What ownership looks like at this level You are expected to  own the deliverable . That means:  Working independently on a well-defined model, workflow, dataset, or component   Producing reliable and repeatable outputs rather than one-time analyses   Adding appropriate validation and basic monitoring   Documenting assumptions, methodology, limitations, and usage   Demonstrating the output and explaining how it supports the business   Raising risks and ambiguity early   Leaving the work in a condition that another team member can operate or extend     You will receive guidance on broader product direction, methodology, and complex stakeholder decisions, but you sho
