We are looking for junior data scientists to lead and support data processing and analysis tasks, such as building data pipelines, monitoring data quality, developing documentation, applying statistical and data science methods, and creating data visualizations.  Our junior data scientists underpin our company's core offerings in program improvement and data science, which yield crucial evidence and information for policy and decision makers. Junior data scientists are on the data scientist career track at Mathematica.

This position focuses on health policy, which includes projects such as:

  • Monitoring the impacts of an alternative payment model for primary care in terms of care quality, cost, and health outcomes for diverse beneficiaries, using claims from thousands of primary care practices across the country and predicting future hospital costs and behavior
  • Developing and testing how claims and survey data from federal and state-level programs could be used to measure patients’ experience of care, quality of life, care coordination, and long-term outcomes for beneficiaries enrolled in both Medicare and Medicaid
  • Creating an interactive data visualization tool to help local policy and decision makers understand how social determinants of health are related to health outcomes in their county, using open source data from public agencies and non-profits

Specifically, our junior data scientists contribute to team-based projects by:

  • Co-developing analysis plans with a data scientist
  • Leading and managing small teams and tasks with oversight from a data scientist
  • Writing and maintaining programming systems in languages such as Python and R to obtain, combine, and transform datasets on cloud, internal, and client servers

  • Experience executing data science and statistics techniques including machine learning algorithms, network analysis, or natural language processing
  • Ability and desire to work independently as part of an interdisciplinary team that may be geographically dispersed. This includes being able to learn resources such as self-guided tutorials, package documentation, and academic articles and willingness to constantly learn and contribute to knowledge sharing with team members.
  • Experience with reproducible research principles, version control, interactive visualizations, tidyverse, R Shiny, R Markdown, pandas, and/or scikit-learn
  • Desired but not required: experience with healthcare datasets (for example, Medicare or Medicaid claims and enrollment data), Bayesian statistics experience (especially with Stan), production-quality machine learning applications, cloud computing environments, and algorithmic fairness and ethics
