What if you could use simulation and analysis to help develop an entirely new type of engine?
Liquid Piston 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.

We’re looking for a motivated engineering student who enjoys solving complex problems and wants hands‑on experience with simulation and analysis.
You’ll help evaluate engine performance, thermal behavior, structural integrity, fluid dynamics, and system-level interactions. Your work will help the engineering team understand how designs perform, identify opportunities for improvement, and make better decisions before and during physical testing.
The ideal candidate is curious, analytical, detail-oriented, and excited to learn. You don’t need to know everything coming in — we’re looking for someone who can think through problems, learn quickly, and apply engineering fundamentals to real-world challenges.

• Develop and run simulation models supporting engine performance, thermal, structural, fluid, and system-level analyses.
• Analyze simulation results to identify trends, performance drivers, and potential design improvements.
• Support modeling of engine and propulsion system behavior across different operating conditions.
• Assist with evaluating design concepts and engineering tradeoffs.

• Compare simulation results against experimental and test data.
• Support validation and improvement of simulation models.
• Work with test engineers to understand discrepancies between predicted and measured results.
• Use test data to improve the accuracy and usefulness of engineering models.
