The Senior Data Engineer ensures data flows are reliable, repeatable, secure, and aligned to architectural standards required for transferring legacy datasets into modern cloud environments.

Your future duties and responsibilities:

Data Pipeline Development & Engineering
• Design, build, and optimize scalable data pipelines enabling ingestion, transformation, and loading of large datasets.
• Implement ETL/ELT processes supporting multi source, multi format data migration.
• Develop data models, schemas, mapping artifacts, and integration structures for legacy to cloud migration.
• Enhance automation, performance tuning, throughput, and fault tolerance within cloud based pipelines.
Data Quality, Transformation & Validation
• Lead data cleansing, normalization, enrichment, and validation efforts across legacy sources.
• Perform root cause analysis on data anomalies and guide corrective actions.
• Coordinate with QA/Test Engineers to embed data validation and automated testing into pipeline workflows.
Cloud Integration & System Support
• Support data engineering activities within AWS cloud environments (preferred).
• Collaborate with Cloud Engineers, DevSecOps teams, Migration Engineers, and system developers to integrate data flows with program architecture.
• Ensure compliance with security, logging, auditing, and handling requirements across environments.
Technical Leadership & Collaboration
• Mentor Data Migration Engineers and Mid Level Data Engineers on pipeline operations and data best practices.
• Participate in technical reviews, sprint activities, and architecture discussions.
• Support migration readiness assessments, backlog refinement, and multi team planning.
Documentation, Reporting & Risk Management
• Produce detailed documentation including pipeline diagrams, mapping specs, data dictionaries, and process guides.
• Track migration progress, pipeline performance, data quality status, and operational risks.
• Identify blockers affecting migration throughput and support timely mitigation.

Required qualifications to be successful in this role:

• Must have Active Top Secret Security Clearance.

• Bachelor’s degree and 8+ years of experience in data engineering, ETL development, or large scale data operations.
• Hands on experience building pipelines for structured/unstructured data across enterprise environments.
• Strong proficiency in data modeling, transformation logic, and automation.
• Familiarity with cloud environments (AWS preferred), DevSecOps tooling, and scripting languages.
• Excellent analytical, documentation, and problem solving skills.
Preferred Qualifications
• Experience with petabyte scale or multi system migration programs.
• Background supporting DOJ, FBI, Intelligence Community, or national security customers.
• Experience with CI/CD integration, automated testing pipelines, or micro service architectures.
• Advanced knowledge of ETL frameworks, distributed compute tools, or cloud native data services.
