Convert SAS code, workflows, and analytical processes into maintainable Python solutions.
Compare and validate SAS and Python outputs to ensure functional equivalency and accuracy.
Develop automated testing frameworks and validation processes for migrated applications.
Perform data analysis and investigate anomalies, inconsistencies, and unexpected model behavior.
Create technical documentation, validation reports, migration plans, and process diagrams.
Collaborate with business stakeholders, statisticians, developers, and project teams to implement analytical solutions.
Support modernization initiatives and continuous improvement of analytical systems and processes.
Required Qualifications:
Bachelor’s degree in Computer Science, Data Science, Statistics, Mathematics, Engineering, Information Technology, or related field.
4+ years of experience developing analytical solutions using SAS and Python.
Strong experience with SAS Base Programming, SAS Macros, and SAS analytical workflows.

Experience testing, validating, and analyzing statistical or predictive models.
Experience conducting model performance evaluations and impact analyses.
Experience migrating SAS applications, scripts, or workflows to Python.
Strong understanding of algorithms, data analysis, and quantitative methodologies.
Excellent analytical, troubleshooting, and problem-solving skills.
Strong communication and documentation skills.
Ability to work independently and as part of a team.

Preferred Qualifications:
Previous experience supporting the U.S. Census Bureau or other federal statistical agencies.
Active or previously held Census Bureau suitability determination, Public Trust, Secret Clearance, or equivalent federal clearance.
Experience with survey processing systems, demographic analysis, economic statistics, or federal statistical programs.
Experience with machine learning frameworks such as Scikit-Learn, XGBoost, or TensorFlow.
Experience with cloud platforms such as AWS, Azure, or Google Cloud.
Familiarity with Git, CI/CD pipelines, and containerized environments.
Experience with SAS Viya and modern analytics platforms.
Key Competencies:
Creative problem-solving with a strong visual and storytelling instinct
Curiosity and experimentation with emerging technologies, particularly AI
Strategic mindset with the ability to connect content to broader campaign goals
Strong collaboration and communication skills
