Senior Engineer, XBAT Simulation Modeling

JOB DESCRIPTION:

The Software Integration & Operations (SIO) group turns frontier autonomy into mission-ready aircraft. We own the commit-to-flight pipeline—deterministic simulation at cluster scale, HIL/VIL integration, CI/CD, automated testing, and release engineering. Our goal is simple: make AI fly—safely, repeatably, and fast.

As aSenior

Modeling & Simulation Engineer, you will be dedicated to Shield AI’s next-generationaircraftprogram,advancing our infrastructure toenableastreamlinedsimulationtestpipeline.

You’lldesign, build, and scalethemodels andinfrastructureneeded touse Shield’s simulation platform for qualified software validation efforts.

Your simulation infrastructure will enable developers to test faster, system engineers to evaluate performance earlier, and release engineers to ship with confidence.

• 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 realaircraftbehavior and mission scenarios.
• Develop infrastructure for CI integration, parallel simulation execution, and automated regression testing.
• Profile,optimize, and validate
  
  C++ codebases for performance, determinism, and fidelity.
• Contribute to architecture decisions that define the next generation ofaircraftsimulation tools within Shield AI.
• Mentor engineers and guide best practices in C++, simulation architecture, and performance engineering.

• BS or MS in Computer Science, Aerospace, Robotics, or related field.
• 8+ 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 Dev Ops-integrated simulation workflows, including CI/CD and automated hardware testing environments.

• 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.
