What You'll Own

• Architecture, design, development, and integration of modern C++ (C++11 and newer) systems for submarine combat systems
• Technical direction across application, middleware, interface, and deployment layers, including legacy migration to Kubernetes
• Distributed application design using APIs, gRPC, Protocol Buffers, and messaging middleware such as DDS or AMQP
• Integration of COTS, open-source, and custom-developed software components
• Diagnosis of complex software, networking, concurrency, performance, and integration issues in lab and on Navy platforms
• Unit, component, integration, and system-level test strategy, and team adherence to it
• Code and design reviews, engineer mentorship, and status, risk, and recommendation briefs to program leadership
• Secure coding, configuration management, and engineering best practices across the team

Required

• Active DoD Secret clearance at time of hire
• Bachelor's in Computer Science, Computer Engineering, or related field
