• Develop robust ETL/ELT processes to ingest, transform, and load data from diverse and often classified sources, ensuring data integrity and proper handling.
• Implement data quality checks and monitoring to guarantee the accuracy and availability of mission-critical data.
• Build and manage data infrastructure in DoD cloud environments (e.g., AWS GovCloud, Azure Government) and on-premises classified networks.
• Design and implement data warehousing, data lakes, and data models that are optimized for performance and security in a high-stakes environment.
• Implement security controls, data governance, and access management compliant with DoD policies, STIGs (Security Technical Implementation Guides), and data classification levels.
• Collaborate with intelligence analysts, data scientists, and mission stakeholders to understand their data requirements and deliver effective solutions.
• Create and maintain comprehensive technical documentation for data architectures, pipelines, and processes in accordance with DoD standards.
• Automate manual processes and optimize data delivery to improve the efficiency and effectiveness of mission support operations.
• Other duties as assigned.

• Bachelor’s degree in computer science, Engineering, Information Systems, or a related technical field.
• 5+ years of progressive experience in data engineering, with a significant portion of that time spent in a DoD, IC, or other federal agency environment.
• Demonstrated experience leading the design and architecture of complex, large-scale data solutions from requirements gathering to deployment.
• Proven track record of mentoring junior engineers and providing technical guidance to the team.
• Extensive hands-on experience building and optimizing data pipelines in government cloud environments (AWS GovCloud, Azure Government) and on-premises classified networks.
• Deep experience handling, processing, and securing data across various classification levels (CUI, Secret, TS/SCI).
• IAT/IAM Level II or III Certification.
• Active Secret with the ability to obtain TS/SCI clearance
• Successfully pass background and drug screening

Preferred Qualifications:

• A master’s degree desired.
