Senior Engineer, XBAT Simulation Infrastructure (TX/SD/Bos) (R4543)

What You'll Do

• Build and scale simulation frameworks for integrated testing of autonomy, GNC, and embedded systems in C++. 
• Design deterministic, high-performance simulation tools capable of faster-than-real-time execution for development, testing, and release. 
• Implement scenario simulation tooling and formal test infrastructure. 
• Collaborate across autonomy, embedded, GNC, and test engineering to ensure the simulation mirrors real aircraft behavior and mission scenarios. 
• Profile, optimize, and validate C++ codebases for performance, determinism, and fidelity. 
• Perform verification & validation (V&V) analysis activities on model tools.
• Contribute to architecture decisions that define the next generation of aircraft simulation tools within Shield AI. 
• Mentor engineers and guide best practices in C++, simulation architecture, and performance engineering. 

Required Qualifications

• BS or MS in Computer Science, Aerospace, Robotics, or related field. 
• 5+ years of experience in software development, with emphasis on modern C++ (C++17 or later) and performance optimization. 
• Proven experience developing or integrating simulation systems for robotics, aerospace, or autonomous systems. 
• Strong grasp of real-time and deterministic software design, including multi-threading, synchronization, and memory management. 
• Experience with DevOps-integrated simulation workflows, including CI/CD and automated hardware testing environments. 

Preferred Qualifications

• Understanding of rigid-body dynamics, kinematics, and basic flight and sensor mechanics. 
• Familiarity with sensor and actuator modeling and integrating avionics or autonomy software within simulation.
• Working knowledge of Python for data analysis, test automation, or simulation orchestration.  
• Ability to debug complex build and runtime environments (CMake, CPM, dependency management, logging, profiling tools). 
• Strong collaboration and communication skills across software, hardware, and systems disciplines.
