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

Aircraft Simulation Team

The Aircraft Simulation team turns frontier autonomy into mission-ready aircraft. We own the commit-to-flight pipeline—deterministic aircraft and mission simulation, HITL/SITL integration, CI/CD, and tooling for automated flight qualification testing. Our goal is simple: make AI fly—safely, reliably, and fast.

What You'll Do

• Develop models and infrastructure for the integrated simulation pipeline in C++
• Design, build, and scale novel aircraft subsystem models
• 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
• Ability to obtain a S//SAR level security clearance desired

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
