Job Description
Distributed Systems Engineer Build authorization and data processing systems at massive scale for the Department of Defense. Design distributed architectures handling complex access control policies supporting tens of thousands of concurrent users, high-volume data pipelines, sophisticated data governance requirements, workflow orchestration engines, robotic process automation, and AI prompt engineering systems. Architect distributed caching strategies, implement event-driven data processing, build high-performance policy evaluation engines, and solve algorithmic challenges around efficient authorization and data access at scale. Work on distributed consensus problems, cache consistency, ETL optimization, workflow state management, and real-time monitoring of complex data flows. Design elegant algorithms for policy evaluation, optimize critical processing paths, implement sophisticated caching and data governance strategies. Handle data lineage tracking, audit trail generation, compliance validation across distributed systems, and orchestration of complex automated workflows. Develop AI prompt engineering solutions that dynamically answer questions across distributed, classified data sources. Computer science theory meets real-world constraints. Constantly tackle new challenges - always learning and pushing boundaries with a team that gets things done. Required: Active TS/SCI with CI Poly, 5+ years distributed systems, experience building scalable systems supporting tens of thousands of concurrent users, data processing, algorithm design, DoD experience. Bonus: Event streaming platforms, data governance, performance optimization, workflow engines, AI/ML systems.
