Job Description:

Shield AI is seeking a Senior Engineer to help design and develop the middleware framework upon which Shield AI autonomy is developed. As part of the Hivemind Foundations team, you’ll focus on building the high-performant, reliable, and robust foundational layer of the Hivemind SDK, EdgeOS. The Hivemind Foundations team ensures that autonomous systems have the functionality required to deploy to platforms operating in some of the most restrictive and demanding environments around the world. They also create the tools that enable autonomy engineers develop, understand, debug, and rapidly iterate on complex autonomous systems. 

What you'll do:

  • Own the architecture and implementation of features critical to EdgeOS and EdgeOS RT middleware. 
  • Develop runtime services and abstractions that operate across Linux, real-time operating system, and resource-constrained computing platforms. 
  • Design and develop the tooling used to evaluate, observe, and debug autonomous systems. 
  • Contribute to and extend EdgeOS Language, Hivemind’s interface definition language, which defines how data is represented within autonomous systems, between agents, and with third-party systems. 
  • Collaborate closely with autonomy, systems, simulation, and test engineers to deliver capabilities from initial design to integration. 
  • Raise the engineering bar though design and code reviews, technical guidance, documentation, and mentorship. 

Required qualifications:

  • Bachelor’s degree in Computer Science, Electrical Engineering, or a related field. 
  • Typically requires a minimum of 7 years of related experience with a Bachelor’s degree; or 6 years with a Master’s; or 4 years with a PhD; or equivalent work experience. 
  • Strong proficiency in C++11 or newer in a production environment. 
  • Experience designing, developing, and debugging multithreaded systems. 
  • Experience developing software for real time operating systems and embedded platforms. 
  • Strong understanding of systems programming concepts, including concurrency, memory management, resource constraints, and performance optimization. 
  • Experience writing automated tests and clear technical documentation. 

Preferred qualifications:

  • Experience with C++17 or newer standards. 
  • Experience writing MISRA C++ or comparable coding standards for safety-critical or airborne systems. 
  • Experience with systems engineering design principles and requirements. 
  • Experience software assurance frameworks such as DO-178C. 
  • Familiarity with ROS2 or similar robotics frameworks. 
  • Experience with interface definition languages, serialization systems, or code-generation tooling. 
  • Knowledge of CMake and Nix build systems. 
  • Experience profiling and debugging complex software across multiple hardware and operating-system environments.

What We Do

At Shield AI, you won't wait years to see your work reach the field. You'll build hardware and software that operates in the real world right now, in the hands of the people who depend on it. Hivemind, our AI pilot, has been flying since 2018. It has flown more than 30 platforms, including an F-16, and it now sits under a U.S. Air Force production contract for Collaborative Combat Aircraft. When you write code or shape a system here, you contribute to technology with a proven flight record and a clear production future. V-BAT flies intelligence, surveillance, and reconnaissance missions with an operational record that stretches from Ukraine to the Indo-Pacific. It delivers eyes where they matter most, in the most demanding conditions on earth. The teams behind it watch their work get tested where the stakes are real. X-BAT takes its first flight this year. It's an AI-piloted fighter that needs no runway, built to operate where traditional aircraft can't. Join now and you help shape a program at its earliest, most formative stage. That's the kind of ground-floor work that defines a career. Do the most impactful work of your life, on problems that matter. Autonomy at this level asks a lot of you. You'll take on problems in perception, planning, and control that few teams anywhere are equipped to solve. You'll work across disciplines, from aerospace and robotics to machine learning and systems engineering, alongside people who hold themselves to an exacting standard and expect the same from you. Our mission is clear: protect service members and civilians with intelligent systems. That purpose runs through every decision, every design review, and every deployment. It's why the work here carries a weight you can feel. Ready to join our mission? Explore our open roles and find where you fit.

Why Work With Us

Founded in 2015 by a former Navy SEAL, Shield AI builds AI pilots and uncrewed aircraft. Veterans aren't an afterthought here, they're at every level. It's why the work carries weight: AI pilots and uncrewed aircraft flying real missions, from Ukraine to the Indo-Pacific, protecting service members and civilians.
