Let us help align you to the right role based on your strengths and interests.

Your Impact

You’ll work across the data lifecycle—design, development, optimization, and integration—supporting systems that operate at scale in high-stakes environments. Day-to-day, that can look like:

• Designing and developing database solutions across relational and NoSQL environments to support complex mission systems
• Building and maintaining relational and/or object-oriented databases
• Developing tools for data ingestion, transformation, and storage
• Translating user and system requirements into scalable data architectures
• Optimizing database performance, storage, and retrieval across large datasets
• Supporting data flow, integration, and accessibility across distributed systems
• Creating and refining queries, scripts, and data pipelines to support analysis and operations
• Evaluating and improving existing database structures and system performance
• Collaborating with software engineers, analysts, and system engineers to deliver integrated solutions
• Supporting database efforts from initial requirements through testing and deployment
• Contributing to system design decisions, including data modeling, storage strategies, and architecture trade-offs

Qualifications

• All positions require an active TS/SCI with polygraph
• Experience working with databases such as Oracle, MongoDB, or similar relational and NoSQL technologies
• Experience developing queries, scripts, or data pipelines to manipulate and manage data
• Strong understanding of data modeling, storage, and retrieval concepts
• Experience or interest in working with large, complex, or distributed datasets
• A collaborative mindset with the ability to work independently and on a team
• A degree in Computer Science, Information Technology, Database Management, or a related field (or equivalent experience)

Nice to Have

• Experience with cloud-based data solutions (e.g., AWS, S3, RDS, or similar)
• Familiarity with big data tools or distributed data processing frameworks
• Experience with performance tuning, data optimization, or database scaling
• Exposure to DevOps, CI/CD, or containerized environments
• Experience working in mission or high-performance computing environments
