Full Job Description
JOB DESCRIPTION:

The Software Integration & Operations (SIO) 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 sensor and communications model suite so that our operator training and internal engineering pipelines have a seamless translation from sim to real results.

What You'll Do
    • Develop and enhance radar sensor models for use in simulation and evaluation of aeronautical vehicles.
    • 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.


Required Qualifications
    • BS or higher in Aerospace Engineering, Applied Math, Physics, or related field with 3+ years of aerospace modeling experience.
    • C++ foundation with experience implementing numerical methods.
    • Demonstrated experience with aerospace models such as: Radar sensors, Radio communications systems
    • Experience validating simulations against real-world or experimental data.
    • Ability to write clear documentation explaining assumptions, limitations, and expected behaviors of models.
    >


Preferred Qualifications
    • 1+ years of experience working on pilot/operator training systems.
    • Experience with Eigen or SciPy for model prototyping and validation.
    • Familiarity with state estimation sensor models (GPS, IMU, Gyro, etc) for simulation environments.
    • Demonstrated experience with payload sensor models including: Laser senros, IR and optical cameras
    • Knowledge of uncertainty quantification and statistical analysis methods.
    • Experience with parallelization or GPU acceleration for compute-heavy models.
    • Strong problem-solving mindset with a collaborative and detail-oriented approach.
    • Familiarity with Python for test automation and data analysis pipelines.
    • Passion for aerospace and autonomous vehicle systems.
