About the role
- BLN24 is seeking a mid-level Data Engineer to support a large-scale data and analytics platform modernization effort for a federal statistical agency client.
Responsibilities
- Design, build, and maintain ETL/ELT pipelines to ingest data from multiple source systems into the platform's central data store
- Develop and maintain data ingestion workflows for both batch and near-real-time sources
- Implement data validation, cleaning, and transformation logic to ensure data quality and consistency across pipelines
- Build and maintain data models and schemas that support downstream analytics and reporting needs
- Document data lineage, transformation logic, and pipeline architecture for governance and reproducibility
- Design and implement benchmarking approaches that compare production data against historical, modeled, or external reference values
Requirements
- Bachelor's degree in Data Science, Statistics, Computer Science, Engineering, or related field (or equivalent experience)
- 3-5 years of experience spanning both data engineering and data science/statistical analysis
- Strong proficiency in Python, including experience with data engineering libraries (e.g., pandas, PySpark) and statistical/ML libraries (e.g., scikit-learn, statsmodels)
- Experience working with SQL and relational/distributed data systems
- Ability to work within a federal data environment, including familiarity with data sensitivity tiers and access/disclosure constraints
- Strong communication skills, with the ability to explain technical/statistical concepts to non-technical stakeholders
- Requires U.S. citizenship and ability to obtain a public trust or other clearance/suitability determination typical of federal contractor engagements
- You can join one of the fastest growing companies headquartered in the Washington DC Metro Area.
- We give you the opportunity to work in different sectors, so you have the chance at variety while maintaining stability.
Nice to have
- Prior experience supporting federal statistical agencies or other federal data programs
- Familiarity with Databricks or modern lakehouse architectures (Spark, Delta Lake, etc.)
- Experience with workflow orchestration tools (e.g., Airflow, Databricks Workflows)
- Experience designing anomaly-detection or outlier-detection approaches beyond standard threshold-based methods
- Exposure to disclosure avoidance concepts or working with regulated/protected government data
- Experience working across multiple coding environments (Python, R, SAS) within the same analytics platform
Benefits
- We make sure to keep them in the game by giving them access to generous medical, dental, and vision plans.
- Monitor pipeline health, troubleshoot failures, and implement logging/alerting for data quality issues
- Develop and evaluate machine learning models where appropriate, balancing predictive performance with interpretability for non-technical stakeholders
Company info
- We find strength in teamwork-a better you is a better us
- BLN24 is an award-winning Management Consulting Firm that supports the U.S. Federal Government in successfully achieving their mission and goals.
- Our service and solutions delivery start with understanding each client's end-state, and then seamlessly integrating within each Agency's organization to improve and enhance strategic and technical operations and deployments.
- Position Overview:
- This is a hybrid role: data engineering (building and maintaining the pipelines that bring data into the platform) and applied data science (using classical statistics and machine learning to analyze that data once it's available).
- The ideal candidate is equally comfortable writing production-grade ingestion and
- transformation code as they are designing and validating a statistical or ML model.
- This role works closely with SMEs across multiple program areas to understand source data, build reliable ETL/ingestion pipelines, and apply analytical methods - anomaly detection, statistical modeling, and machine learning - to support operational decision-making.
- We are an equal opportunity employer and place a high value on diversity and inclusion at our company.
Equal opportunity
- BLN24 is an Equal Opportunity Employer.
