Senior Software Engineer, Shield AI

• Strong proficiency in modern C++ (C++11 or newer) and professional experience developing software for embedded Linux systems
• Experience designing and deploying state estimation algorithms (e.g., EKF, UKF) in real-world defense or aerospace applications
• Familiarity with developing for constrained environments requiring deterministic timing and high reliability
• Professional experience with continuous integration (CI) workflows and automated C++ testing
• Practical understanding of inertial navigation systems (INS), GNSS integration, and navigation error modeling
• Ability to deploy and maintain robust, efficient, production-level C++ code
• Familiarity with MATLAB or Python for prototyping is acceptable; however, primary development experience must be in C++

Desirable

• Research and develop advanced state estimation and navigation algorithms to ensure assured Position, Navigation, and Timing (PNT) in contested environments
• Design, write, and deploy production-quality C++ software for aviation platforms requiring real-time, deterministic performance
• Build and maintain comprehensive unit, integration, and system-level tests to validate navigation software performance under operational constraints
• Develop modeling, calibration, and simulation tools for inertial and aided navigation technologies used in airborne platforms
• Participate in agile-based product planning, feature definition, capacity estimation, and cross-team collaboration
• Contribute to ongoing system performance evaluation, regression analysis, and V&V (Verification and Validation) efforts
• Shield AI’s Hivemind autonomy team is building next-generation autonomy and navigation solutions for resilient, mission-critical systems. As a Senior Engineer, you will contribute directly to the design, development, integration, test, and deployment of the Hivemind navigation stack.
• We seek engineers with experience delivering robust navigation and state estimation solutions for defense aviation systems, ISR platforms, or other DoD-relevant applications, with strong expertise in C++ software development for embedded Linux systems

• Candidates will be asked to complete a C++ coding exercise as part of the interview process to assess comfort with modern software design practices and system-level thinking
