Core Simulation Engineer - Mid Level

About Pratt Miller, an Oshkosh company

Pratt Miller is a product development company in motorsports, defense, and mobility industries providing clients with product engineering and low-volume production solutions. Our range of research & development, engineering, prototype manufacturing, test & validation, and low-rate production capability help our customers bring their high-quality products to market faster.

The Core Simulation Engineer develops, validates, and deploys high-fidelity, numerically efficient multibody vehicle models and simulation tools to support vehicle performance analysis and development across a range of environments. The primary simulation capabilities include:

Dymola-based vehicle and subsystem modeling libraries for desktop, XiL, and real-time applications

Lap time simulation (LTS) tools

Simulation workflows for tool chain integration

Vehicle dynamics analysis processed and tools

This role also leads correlation and continuous improvement efforts, contributes to simulation infrastructure, and collaborates cross-functionally while providing expertise to internal teams and customers.

The ideal candidate has a strong foundation in vehicle dynamics and multibody simulation, with hands-on experience in model development, correlation, and simulation toolchains for high-performance vehicles. They combine solid programming and analytical skills with a self-driven, detail-oriented, and collaborative approach to solving complex engineering problems.

ESSENTIAL DUTIES AND RESPONSIBILITIES:

Typical responsibilities include, but are not limited to:

Develop and maintain numerically efficient multibody models of vehicles, subsystems, and tires in Dymola/Modelica to enable high-quality simulation and analysis

Adapt and optimize simulation models for multiple environments, including desktop, real-time, XiL (MiL/SiL/HiL), and Driver-in-the-Loop (DiL) applications

Design, enhance, and support simulation workflows, model architectures, and analysis utilities, ensuring seamless integration within the broader Pratt Miller vehicle performance ecosystem

Develop and advance lap time simulation tools, methodologies, and workflows with a focus on accuracy, robustness, and computational efficiency

Lead correlation activities by comparing simulation results to track and rig test data, continuously improving model fidelity and predictive capability

Diagnose and resolve model performance, numerical stability, and correlation issues; communicate gaps and improvement opportunities to the core development team

Execute simulation studies to support development efforts, synthesizing results into clear, concise technical reports and recommendations

Maintain model quality through rigorous documentation, version control, and validation practices

Serve as a subject matter expert in vehicle dynamics and simulation, providing technical guidance to engineers and customers

Collaborate cross-functionally with vehicle dynamics, controls, software, and test teams to align simulation capabilities with broader program objectives

Partner with internal programs and external customers to deploy, apply, and support Pratt Miller simulation products and capabilities
