Quick Position Overview:

• US Citizenship is required
• Bachelor's Degree is required
• minimum of 3-5 years' position related experience is required

The Role: 

STS is looking for a Mid-Level Data Scientist to join a federal data engineering team. You will work on a modern AWS-based federal data platform, building AI/ML capabilities and delivering production-ready analytical products that support critical government decision-making. A curiosity-driven mindset, strong quantitative skills, and the ability to translate analytical outputs into production-ready data products conforming to agency standards are prerequisites for this position. 

This position is contingent upon contract award. 

The Mid-Level Data Scientist at STS will: 

• Build and maintain knowledge bases, vector stores, and Retrieval Augmented Generation (RAG) pipelines using Amazon Bedrock and Amazon OpenSearch Services to make financial and regulatory datasets AI-ready for advanced analytics and machine learning consumption 

• Support the development, validation, and operationalization of statistical outputs and derived data products; coordinate with the agency data science team and SME data scientists to implement Airflow DAGs and AWS Glue jobs that ensure automated, recurring updates 

• Support transition of data science outputs into production by validating accuracy, completeness, and reporting readiness; ensure all production data products are incorporated into the agency's ETL load and gap reporting infrastructure 

• Develop and validate machine learning models and analytical pipelines using large-scale financial and regulatory datasets in the data lake 

• Leverage AI-assisted development tools for code generation, debugging, and performance tuning; adhere to agency security standards and applicable federal AI governance requirements 

• Write Python 3.10 code conforming to PEP 8; integrate analytical pipelines with the agency's ETL metadata infrastructure and produce required load and gap reporting outputs 

• Support entity resolution work to ensure consistent identification and linkage of records across high-volume financial datasets 

• Produce required documentation for all analytical models and pipelines: methodology, data lineage, model assumptions, refresh schedules, and IV&V Questionnaires 

• Write automated tests achieving the 90% minimum code coverage threshold; complete security scans at least once per sprint as part of the Definition of Done per OWASP ASVS Level 2 

• Participate in 2-week sprint ceremonies, quarterly PI planning, backlog refinement, and agile delivery using JIRA and GitHub 

Education and Experience: 

Required 

• Bachelor's degree or higher in Data Science, Statistics, Computer Science, Mathematics, or a related quantitative field 

• 3-5 years of experience in data science, machine learning engineering, or quantitative analytics 

• Proficiency in Python 3.10 (PEP 8) including pandas, NumPy, scikit-learn, and related libraries 

• Hands-on experience with Amazon Bedrock, knowledge bases, vector stores, and RAG pipeline design on AWS 

• Experience with Amazon OpenSearch Services or equivalent vector/search infrastructure 

• Experience with Apache Airflow (MWAA) for DAG-based pipeline orchestration 

• Familiarity with AWS Glue, S3, and Apache Spark for large-scale data processing 

• Experience with SQL and query tools such as Trino, Athena, or Redshift 

• Experience working with large-scale financial or regulatory datasets is strongly preferred 

• Knowledge of federal AI governance requirements and responsible AI practices in a government setting 

• Experience with agile development, CI/CD pipelines, GitHub, and sprint-based delivery 

• Familiarity with FISMA, NIST 800-53, and Zero Trust principles 

• Must be able to work 8am-5pm Eastern Time regardless of home location 

• Active federal public trust suitability determination or ability to obtain one required
