Simulation Engineering Intern - Spring 2027 | LiquidPiston

LiquidPiston•Suffield, CT

1d•Onsite

About The Position

LiquidPiston is an advanced technology company developing compact, high-performance rotary engines based on a novel thermodynamic cycle. Our technology is being developed for demanding applications across defense, aerospace, and commercial markets. As a Simulation Engineering Intern, you won’t just be observing engineering work - you’ll contribute to it. You’ll work alongside experienced engineers on real propulsion development problems, using modeling, simulation, and data analysis to help guide design decisions and support physical testing. This is an opportunity to take what you’ve learned in the classroom and apply it to technology that is being actively developed and tested. You’ll work in a fast-paced R&D environment alongside mechanical, combustion, controls, and test engineers and gain exposure to the full engineering development process.
