At Mathematica, we take pride in our commitment to diversity. Building an inclusive culture that draws on the individual strengths of employees from different ethnic backgrounds, cultures, lifestyles, abilities, and experience is key to our success.

We are looking for a Data Scientist 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.  This position will either work remotely or flexibly in one of our office locations.

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

• Enhancing knowledge management and library curation across all VRDC projects by developing Python scripts that leverage large language models for automated document classification.
• 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, this Data Scientist contributes to team-based projects by:

• Co-developing analysis plans with a senior data scientist or researcher
• Writing and maintaining programming systems in languages such as Python and R to obtain, combine, and transform datasets on cloud, internal, and client servers
• Developing and maintaining documentation
• Implementing quality assurance practices, such as version control and testing
• Conducting analysis and communicating results, both to clients and internal teams, such as descriptive statistics, data visualizations, and model diagnostics
• Leading and managing small teams and tasks with oversight from a senior staff member

Position Requirements:

Requirements:

• Bachelor’s degree, with an academic record including courses in subjects such as statistics, data science, data analytics, mathematics, operations research, computer science, and/or social science; equivalent years of experience can be substituted
• Demonstrated interest and/or experience using programming and data science and/or statistics to contribute to projects with a policy/social impact in academic and/or professional settings
• At least three years of experience performing data cleaning and analysis using programming languages such as R, Python, or Julia in the academic, extra-curricular, or professional environment
• Experience executing data science and statistics techniques including regression modeling, 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 from and apply 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, and common packages/libraries for supporting data science work in R, Python, and/or Julia (e.g., tidyverse, R Shiny, R Markdown, pandas, NumPy, scikit-learn, MLJ.jl, DataFrames.jl, and/or Makie.jl).
• Desired but not required: experience with healthcare datasets (for example, Medicare or Medicaid claims and enrollment data), production-quality machine learning applications, cloud computing environments, and algorithmic fairness and ethics

This position offers an anticipated annual base salary range of $75,000- $100,000. This position is eligible for a discretionary bonus based on company and individual performance. To apply, please submit a cover letter (optional), resume, code samples, and salary expectations.

Staff in our Health or Human Services units will eventually work with some of our largest clients, including the Centers for Medicaid & Medicare Services (CMS) and other agencies. Most staff working on these contracts will be required to complete a successful background investigation including the Questionnaire for Public Trust Position SF-85 (https://www.opm.gov/forms/pdf_fill/sf85p.pdf). Staff that are unable to successfully undergo the background investigation will need to be able to obtain work outside these contracts. Staff will work with their supervisor to get re-staffed, however if they are unable to do so it may result in employment termination due to lack of work.
