 * Lead the architecture, design, development, and integration of complex software systems.
 * Develop production-quality software using C++ in a Linux environment.
 * Establish technical direction and make sound design decisions across application, middleware, interface, and deployment layers.
 * Integrate distributed applications using APIs, gRPC, Protocol Buffers, and data-driven interface models.
 * Lead the integration of COTS, open-source, and custom-developed software components.
 * Diagnose complex software, networking, concurrency, performance, and system integration problems.
 * Define unit, component, integration, and system-level test strategies.
 * Lead code and design reviews while promoting secure coding, configuration management, and engineering best practices.
 * Mentor software engineers and coordinate technical work across multiple teams and disciplines.
 * Communicate technical status, risks, recommendations, and recovery plans to program leadership, customers, and partner organizations.
 * Support software integration and issue resolution in laboratory and Navy platform environments.
