Simple Technology Solutions is looking for a Mid-Level Data Scientist to add to our team.

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
