  • Develop mission systems requirements and architectures to ensure overall system effectiveness
  • Select mission system baselines through make vs buy trades and vendor engagements
  • Develop the integration & test verification plan to include resources from bench-level hardware-in-the-loop (HIL) to flight test
  • Define mission system software architectures including baseline processing and advanced algorithm development
  • Drive trade studies and system-of-systems analysis to balance performance, cost, and schedule
  • Serve as a technical subject matter expert for mission systems engineering across the aircraft program
  • Ensure compliance with MIL-HDBK-516C, DO-178C, DO-254, and related standards
  • Collaborate with program management to de-risk architectures and ensure technical maturity gates are met

About Shield AI

Shield AI

Shield AI is a venture-backed defense technology company specializing in artificial intelligence, autonomous systems, and next-generation military aviation. Founded in 2015 and headquartered in San Diego, the company is focused on building advanced software and hardware solutions that enable military forces to operate effectively in the most contested, denied, and high-risk environments. Its technologies are designed to function where traditional systems fail—particularly in GPS-denied, communications-disrupted, and highly dynamic combat scenarios.

At the core of Shield AI’s innovation is its emphasis on software-driven autonomy. Rather than relying on remote human operators, the company develops AI-powered “pilots” capable of independently navigating complex missions, making real-time decisions, and executing objectives with speed and precision. This approach allows autonomous systems to operate with greater resilience, reduced latency, and significantly enhanced survivability in modern warfare environments.

Its mission is to protect service members and civilians through intelligent, autonomous systems. This mission drives the company’s commitment to reducing human risk on the battlefield while expanding the operational reach and effectiveness of defense forces. By combining cutting-edge artificial intelligence with deep operational insight, Shield AI is helping to redefine how military missions are planned, executed, and sustained in the era of autonomous warfare.
