Job description

METECS is seeking a Terramechanics Engineer who is excited about lunar exploration to support high‑fidelity modeling and simulation of lunar terrain. This role emphasizes physics‑based approaches to soil structure interaction, ranging from continuum and discrete element methods to semi‑empirical terramechanics models. This position also includes the use of multi‑body dynamics and simulation frameworks for analysis, design, and validation.

Responsibilities

• Develop, implement, and applyterrain and soil interaction models within coupled multi-body dynamics simulations.
• Workwith higher-fidelity modeling approaches such as continuum mechanics (e.g., SPH-based methods) and/or discrete element method (DEM) simulations to model granular and deformable terrain behavior.
• Maintainand applysemi-empirical terramechanics models (e.g., Bekker-type formulations) as baselines, validation references, or computationally efficient tools.
• Extendterrain interaction models to support deformable or conformable contact elements, including tires or other compliant structures.
• Integrate soil and contact models into simulation frameworks and workflows, including NASA’s Trick environment or similar tools.
• Perform simulation validation through comparison with experimental data, test results, or field measurements.
• Conductuncertainty quantification, sensitivity analyses, and model calibration to assess prediction robustness.
• Collaborate with multidisciplinary teams to interpret results, communicate model assumptions and limitations, and inform system-level decisions.

Required Qualifications

• Master'sor advanced degreein mechanical engineering, aerospace engineering, applied physics, or a closely related technical field.
• Working knowledge of foundational terramechanics principles, including Bekker-type soil–vehicle interaction theories.
• Proficiency in C/C++ and Python for scientific computing, simulation development, and analysis.
• Strong data-analysis skills, including experience working with simulation and experimental datasets.
• Experience developing or applying physics-based models within a simulation environment.
• Clear technical communication and documentation skills.

Desired Qualifications

• Experience with continuum mechanics–based modeling approaches (e.g., SPH or related methods).
• Experience with discrete element method (DEM) simulations or granular material modeling.
• Familiarity with deformable or compliant contact modeling (e.g., tires, tracks, or soft structures).
• Familiarity with NASA’s Trick simulation framework or similar simulation infrastructures.
• Experience with coupled multi-body dynamics and soil–terrain interaction simulations.
• Background in simulation validation, uncertainty quantification, or model verification.
• Experience in aerospace, robotics, off‑road vehicle dynamics, or related terrain‑interaction domains.
