Senior Backend Engineer
Build next-generation authorization and data protection systems for the Department of
Defense. We are solving problems that push the boundaries of distributed systems
engineering - massive scale, microsecond latency, zero tolerance for failure.
Architect high-performance backend services, supporting tens of thousands of concurrent
users across multiple security domains. Build self-healing systems with automatic recovery,
implement sophisticated encryption at enterprise scale, and design algorithms for real-time
policy evaluation and data processing.
Work on complex ETL pipelines processing sensitive data, implement data governance
frameworks ensuring federal compliance, and solve distributed systems challenges around
consistency, availability, and performance. Build workflow engines orchestrating complex
processes, implement robotic process automation, and develop AI prompt engineering
solutions that dynamically answer complex questions across classified systems.
This is hardcore systems engineering where architectural decisions have real consequences.
Your code ships to production quickly with immediate impact on critical national security
systems.
Required: Active TS/SCI with CI Poly, 5+ years backend development, proven experience
building systems that scale to tens of thousands of concurrent users, distributed systems
architecture, data processing/ETL, DoD familiarity. Bonus: Algorithm design, performance
optimization, workflow automation, AI/ML integration.
Location: Reston, VA or JBAB (on-site)
