Sr. Data Scientist

The Data Science and Analytics COE is responsible for leading the creation and development of the overall strategy and direction of data science and advanced analytics at CDW - including ensuring continuity and seamless extension of existing programs, the development of a short- and long-term vision and roadmap, and defining and institutionalizing the role that data and analytics play throughout the organization as the fuel that drives and shapes CDW's priorities and serves as an accelerant for CDW's progress.

The Sr Data Scientist is a key player on the Data Science & Analytics team. Reporting to the Manager of Data Science, this coworker will ensure that machine learning algorithms and data analytics are implemented appropriately, and the results are compiled into meaningful dashboard and reports and is shared with relevant stakeholders, while being responsible for enabling data science and technology best practices.

Key Areas of Responsibility
  • Experimentation: Provide hypothesis and requirements to develop analytic capabilities, platforms and pipelines.
  • Experimentation: Formalize assumptions about how systems are expected to work, create statistical definitions of outliers, and develop methods to systematically identify these outliers. Work out why such examples are outliers and define if any actions are needed.
  • Innovation: Continually research and evaluate emerging technologies.
  • Innovation: Design and run experiments, research new methods, and find new ways of optimizing risk, profitability, and customer experience to consistently disrupt and deliver in a better way.
  • Build and Ops: Develop and implement analytical solutions that the business (as your internal customer), external customers and partners can seamlessly integrate into decision making.
  • Build and Ops: Ability to problem solve and constantly explore customer needs to drive towards impactful business outcomes.
  • Communication & Strategic Management: Communicate complex ideas clearly and simply in business language. Tell a data story with the aid of data visualization to aid understanding.
  • Communication & Strategic Management: Think "beyond the numbers" to deliver business relevant recommendations with audience in mind.
  • Communication & Strategic Management: Partner with IT and Commercial teams to execute the data science roadmap.
  • Communication & Strategic Management: Serve as a central knowledge center for relevant data science tools and techniques.
  • Communication & Strategic Management: Keep current with technical and industry developments.
  • Communication & Strategic Management: Present insights and recommendations to audiences at the desired levels of understanding.
