Senior Engineer, XBAT Simulation Modeling (R4546) (TX/SD/BOS)

What You'll Do

• Develop models and infrastructure for the integrated simulation pipeline in C++.
• Design deterministic, high-performance simulation tools capable of faster-than-real-time execution for development, testing, and release.
• Implement test scenarios and write unit, system, and regression tests.
• Collaborate across autonomy, embedded, GNC, and test engineering to ensure the simulation mirrors real aircraft behavior and mission scenarios.
• Contribute to platform-agnostic simulation tooling to accelerate future development efforts.
• Perform verification and validation (V&V) analysis activities on model tools.
• Conduct system performance analysis and generate reports and visualizations.
• Utilize 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.
• Strong understanding of rigid-body dynamics, kinematics, and basic flight and sensor mechanics.
• Proven experience developing or integrating simulation systems for robotics, aerospace, or autonomous systems.
• Ability to debug complex build and runtime environments (CMake, CPM, package management, logging, & profiling tools).
• Experience with software testing tools (GTest, etc.).
• Experience with model V&V.
• Strong collaboration and communication skills across software, hardware, and systems disciplines.

Preferred Qualifications

• 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.
• Working knowledge of Python for data analysis, test automation, or simulation orchestration.
• Familiarity with aircraft and flight physics modeling.
