## Description

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

As a Modeling & Simulation Engineer, you will be responsible for improving and adding to our world and aeronautical models so that our operator training and internal engineering pipelines have a seamless translation from sim to real results.

### Responsibilities

- Develop and enhance aeronautical physics models (aerodynamics, propulsion, environmental, structural, etc.) for use in simulation and evaluation.

- Translate theoretical models into efficient, reliable C++ implementations with a focus on numerical accuracy and performance.

- Validate models against real-world data and authoritative references, including field test data and calibration procedures.

- Collaborate with simulation and training application teams to ensure models integrate cleanly into operator-facing tools.

- Design automated validation and regression testing strategies for mathematical models to ensure fidelity across releases.

- Prototype and evaluate new modeling techniques (reduced-order models, uncertainty quantification, machine learning–based surrogates) to push the state of the art.

- Document assumptions, equations, and validation results so that both engineers and operators can trust model outputs.
