About the role
We are seeking a driven Data Scientist to join our evolving and dynamic team. This entry-level position is ideal for candidates with a strong mathematical foundation and a passion for predictive modeling. You will build, validate, and maintain multi-variable time series forecasting models to project financial data and agency expenditures over multi-year horizons. Responsibilities include owning the data lifecycle from scraping and transforming raw datasets to rigorous model validation. We value resourceful problem-solvers who adapt quickly to changing data environments and ensure predictive tools remain accurate and resilient.
Responsibilities
- Support development and evaluation of statistical and time series forecasting models, including ARIMA, Prophet, regression, and tree-based models.
- Write and maintain Python scripts to scrape, extract, clean, join, and transform structured and unstructured financial data from web sources, APIs, databases, and raw files.
- Execute established validation workflows, compare model performance using metrics such as RMSE, MAE, and MAPE, and identify potential data-quality or data-leakage issues.
- Assist with analyzing historical pricing, inflation indices, budget cycles, and spending patterns to create features for forecasting models.
- Perform exploratory data analysis and document data sources, assumptions, transformations, model results, and known limitations.
- Create reports, visualizations, and summaries that explain analytical findings to technical and non-technical stakeholders.
- Learn new domain requirements, proprietary databases, customer tools, and forecasting methods with guidance from senior team members.
- Maintain strict compliance with defense security protocols, confidentiality guidelines, and internal data handling policies.
Basic Qualifications
- US Citizenship required; ability to obtain and maintain a Secret Security Clearance.
- Bachelor’s degree in Mathematics, Statistics, Computer Science, Data Science, Economics, Finance, Engineering, or a related quantitative field.
- Recent graduates and candidates with up to two years of relevant professional, internship, research, or academic experience are encouraged to apply.
- Foundational knowledge of linear algebra, calculus, probability, and statistics.
- Working knowledge of Python for data manipulation and analysis, including pandas and NumPy.
- Academic, internship, research, or project experience involving statistical modeling, machine learning, predictive analytics, or time series forecasting.
- Basic understanding of single-variable and multi-variable forecasting methods.
- Understanding of model evaluation concepts, including training and test datasets, error metrics, overfitting, and data leakage.
- Strong attention to detail and the ability to organize, document, and communicate analytical work.
- Strong verbal and written communication skills with the ability to explain technical concepts clearly.
- If applicable: If you are or have been recently employed by the U.S. government, a post-employment ethics letter will be required if employment is offered.
Preferred Skills And Qualifications
- Coursework, internship, research, or project experience in Economics, Finance, Econometrics, Accounting, or time series analysis.
- Experience with scikit-learn, statsmodels, Prophet, matplotlib, or similar analytical libraries.
- Familiarity with SQL, APIs, web scraping, ETL processes, or data-processing tools.
- Experience completing a capstone, thesis, internship, or personal project involving forecasting or predictive modeling.
- Exposure to government, defense, budgeting, or financial datasets.
- Familiarity with inflation adjustments, budget cycles, fiscal years, and macroeconomic factors.
- Familiarity with version control tools such as Git or GitHub.
- Continued education and interest in current and emerging AI/ML technologies.
- Strong problem-solving skills and the ability to work in a fast-paced environment.
